Piaget Polo FortyFive Perpetual Calendar Watch

Filed under: Timepieces / Watches

Piaget Polo FortyFive Perpetual Calendar Watch
At SIHH 2011 I got sneak peak at Piaget's upcoming Polo FortyFive Perpetual Calendar watch. The Piaget Polo FortyFive watch that came out a few years ago has been a remarkable success for the brand in giving it a sport's watch. With chronograph and three-hand variants available, Piaget has designed a Polo FortyFive model with an in-house made perpetual calendar automatic movement.

With an impressive level of symmetry, the dial displays the time, retrograde date, retrograde day of the week, month, power reserve indicator for the movement, time with subsidiary seconds, second timezone, leap-year indicator, and a clever moon phase indicator. All on the dial that is is a few shades of black with while and rose gold.

The 45mm wide case is in titanium with 18k rose gold accents. More 18k rose gold is used on the dial for the hands and some dial rings. At first glance the watch looks a bit like a complex chronograph but actually has an impressive level of features in it. A very utilitarian touch that I appreciate is labeled inset pushers on the side of the case. Perpetual calendar watches often have pin pushers on the side of the case to adjust the calendar functions. Piaget thoughtfully opted to label them to make adjusting the watch less burdensome. See more images of this upcoming Piaget Polo FortyFive watch in the gallery below.

Shia LeBeouf Wears IWC Watch In Wall Street: Money Never Sleeps Movie

Filed under: Timepieces / Watches

IWC watches are displayed on the wrists of the two main characters in the new Oliver Stone movie, Wall Street: Money Never Sleeps. Wasn't this movie supposed to come out already? I think it got pushed. The infamous Gordon Gekko has Michael Douglas wearing an IWC Da Vinci Perpetual Calendar watch in rose gold, while lead Shia LeBeouf is also wearing an IWC perpetual calendar timepiece. Only his character Jacob Moore is wearing an IWC Portuguese Perpetual Calendar in 18k white gold (model ref. IW376205). I guess they both really like knowing the precise date.

Probably too ritzy for his character in real life (maybe he bought the watch after making the money), the Portuguese Perpetual Calendar combines the classic look of the famous Portuguese models, with the intricate complication of IWC's very popular 7 day power reserve automatic perpetual calendar with the date, day of the week, month, leap year, year indicator, power reserve indicator moon phase indicator, and the time. Like I said, the case is in white gold, just over 42mm wide, and retails for $38,800. Check out IWC watches in Wall Street: Money Never Sleeps when it hits theaters soon.

Piaget Emperador Full-Set Coussin Perpetual Calendar Is Brand's One Millionth Watch

Filed under: Timepieces / Watches

Piaget Emperador Full-Set Coussin Perpetual Calendar
After 136 years Piaget has finally reached the point where it will have made 1,000,000 watches. That is really a lot of watches, which averages to about 7,353 watches per year. Though clearly they haven't been consistently making that many from the beginning. Piaget is on a modern mission to reassert itself as fine watch maker as opposed to just a luxury jewelry and timepiece maker. When people think of Patek Philippe for example, they think of "in-house made movements." This association is not always made with Piaget and in-house made movements, though the brand is of the several highly prestigious brands that do make their own movements.

The one millionth watch produced by Piaget is this special Emperador Full-Set Coussin Perpetual Calendar watch. The timepiece will represent watch number 1,000,000 for the brand, as well as 19 other pieces for a total of 20 pieces in this limited edition. The watch case is Piaget's standard Emperador Coussin (cushion) - which is probably the most interesting cushion case out there - probably because it is not a true cushion case. The dial is cushion shaped, but the case itself is actually round. That combined with the design of the lugs make for an interesting optical illusion. This version of the Emperador Coussin is "Full-Set" with diamonds. The case is in 18k gold with 374 diamonds on it (7.5 carats), 12 more diamonds are on the crown, 25 diamonds are placed on the oscillating automatic rotor, and another 263 diamonds (1.2 carats) are placed on the watch dial - while the hands and hour markers are in 18k white gold. Total of 9.9 carats of diamonds on the watch.

Vacheron Constantin Patrimony Traditionnelle Perpetual Calendar Chrono Platinum Watch

Filed under: Timepieces / Watches

With a name like Vacheron Constantin Patrimony Traditionnelle Perpetual Calendar Chrono Platinum watch, what could I possibly add to a discussion about this timepiece? I mean it pretty much sums it up in a four breath title suitable for the king of a no longer existing nation.The 43mm wide watch in all platinum is one of the major highlights of Vacheron Constantin's 2010 watch collection - an offering marked by stark traditionalism and brand DNA. I like this watch because of the straight forward layout of the information as well as the nicely contrasting colors on the dial. Together the looks is very attractive and even displays a trendy gray demeanor throughout the watch. It isn't hard to realize the watch isn't for you, but you can't deny that this is one splendid timepiece.

The movement is all hand-done - displayed through the watch's sapphire caseback window. The In-house made Vacheron Constantin Calibre 1141QP movement features a perpetual calendar (displaying the day, date, month, and leap year), moon phase indicator, 30 minute column wheel chronograph, and the time with a subsidiary seconds dial. I would have liked the movement to be an automatic, but the view you get of the movement in very impressive.

You can tell in the image I snapped that the platinum polish is impressive. Careful though, as platinum begins to pick up hairline scratches easily. Also, platinum is heavy, so you'll need to not be a wimp to wear one of these. I like the character of the moon phase face. It is hard to see here, but check out the Vacheron Constantin marketing image of the watch below to see the Bell Epoque style "emo" moon face. One side of the moon disc has a moon that is frowning, with the other side being a moon that is smiling, I believe. Not sure about price, but I wouldn't believe a nickle under $100,000.

Audemars Piguet Jules Audemars Perpetual Calendar Watch

Filed under: Timepieces / Watches


Here it is, the world's thinnest perpetual calendar watch (only needs to be adjusted once each four years). It is only 9.15mm thick and feels even thinner. the 18k pink gold case is 41mm wide making the Audemars Piguet Jules Audemars Perpetual Calendar watch an impressive and complex watch. The dial comes in two colors, either silvered or brown. The automatic mechanical in-house AP Calibre 2120/2802 movement provides the time (without displayed seconds), moon phase, date, leap year indicator, month, and day of the week. All logically laid out in traditional perpetual calendar fashion. I love the brown dial as it melds with the gold case nicely and the brown alligator strap.

Finishing on the case is superb and it is very comfortable to wear. From the sides you see a brushed finish, while the bezel and lugs are polished. Reading the watch is a breeze and it makes for a comfortable daily wear. Finding an automatic perpetual calendar that is easy to read isn't always easy, and here you can get one that is very thin as well. Turn the watch over and you get to see an intensely engraved and skeletonized automatic rotor with the "AP" initials applied to it, through the sapphire caseback window. For classic style lovers who want a timepiece from a good pedigree, this is a good option. Price for both dial colors is $58,700.

Daniel Roth Athys Moon 2134 Watch

Filed under: Timepieces / Watches

daniel roth athys moon 2134 watch
Daniel Roth's most marketable claim to fame for this new Athys Moon 2134 watch is that it will not require any moon phase calendar adjustment for 125 years. That is of course unless you forget the wind the manually-wound movement and then you are out of luck for that whole impressive 125 year number. Though I have a feeling if you are a proud owner of this watch you'll be very happy to wear it (and wind it) often.

What makes the moon phase function in this watch different than those in other moon phase calendar movement based watches? It has to do with the moon phase complication. Instead of the normal gearing that requires a moonphase to be adjusted every few years, that in the Daniel Roth Calibre 2300 (DR2300) movement has a much larger gear with more teeth. This allows for the movement of the moon through its phases to be much more precise (combined with other mechanisms and gears of course) and thus not require adjustment for such a long period of time. Truly the type of issue only your heirs, or heirs' heirs need concern themselves with.

The Athys Moon 2134 is available in 18k red or white gold in the traditional Daniel Roth watch case shape that you either love or don't. but don't knock it until you get one on your wrist. The moon phase disc is rendered with a more realistic image of the moon's surface while the the rest of the watch dial has the time, a subsidiary seconds dial, and the date. A really good looking and classic watch with a unique take on engineering the moon phase, one of the most desirable and popular complications in the horological enthusiast community.

Thomas Prescher Perpetual Calendar QP1 Watch

Filed under: Timepieces / Watches

thomas prescher watch
There are a few "firsts" for this watch. Included in them is the layout for a perpetual calendar watch, as well as the instant changing of all the indicators. None of that really matters to me, instead I am taken by the unique, but classic good looks in this new watch by the very talented Mr. Thomas Prescher. A independent watch maker in Switzerland, Prescher humbly creates some of the most complex timepieces in the world. He is further the inventor of the "flying triple axis tourbillon" with really can't be fully appreciated until you see it.

This new watch, the Perpetual Calendar QP1 presents the relatively data intensive feat of a perpetual calendar in a simple and appealing manner. Looking at the gold hands from the smallest, the first hand indicates the day of the week (ex. Sunday = 1), the next hand displays the date, and the hand after that displays the month using the hour indexes as indicators for the 12 months. Lastly you have the leap year indicator in digital format at 6 o'clock. All that information, and still the dial looks so clean.

Thomas Prescher watches are made to order - meaning that customizations are welcome. Basic options include a 43mm or 39mm wide case in either 18k gold or 950 platinum. The hands, dial, and alligator straps are all customizable by the buyer. These watches represent ultra luxury and are priced as such. Movements are all in-house made, and the finish of the watches is what you would expect from a watch costing over $200,000 plus, in most cases.

IWC Da Vinci Perpetual Calendar Chronograph Watch

Filed under: Timepieces / Watches

iwc da vinci watch
This IWC presents a first (in my knowledge) complication for watches. This is the first perpetual calendar with a "big" date and month display. I really like how this looks on the face, having the two large display windows polarized horizontally on the dial. While it is easier for me to read the month as a three letter abbreviation, this style will be more convenient when you write out the date in the European style: "25/8/09," as for us Americans, we will have to switch around the numbers in our head. While this Da Vinci Perpetual Calendar watch does not display the day of the week, if you aren't aware of that, you've got other problems. Instead, there is a tastefully small leap year indicator at 6 o'clock, and a full 12 hour chronograph to satisfy you. The chronograph combines both the hours and minute counter into one dial (with two hands) in the 12 o'clock position. This is one of the most simple looking, complex watches out there.

The watch comes in a limited edition of 500 with pieces in 18k rose gold or platinum. The newer Da Vinci style tonneau case measures 44mm wide by 16mm tall. This watch has an automatic in-house IWC caliber 89800 movement that has 474 parts (very complex) and a massive power reserve of 68 hours. Knowing this will help you justify the price of this beautiful IWC Da Vinci watch, which is likely to be $40,000 plus.

Audemars Piguet Tradition Perpetual Calendar Minute Repeater Watch

Filed under: Timepieces / Watches


Each year's new releases from Audemars Piguet reveal how dynamic the watch maker is. From ultra modern, to ultra subdued, there is no limit to how varied their timepieces can be. In stark contrast to some of the more bold offerings this year, the Audemars Piguet Tradition line - with its attractive 39.5mm wide cushion case - adds a new level of ' complication smoothness' to the classically-styled line.

Greatest in this year's Audemars Piguet Tradition line is this Perpetual Calendar with Minute Repeater watch that is actually a very complex timepiece given the sheer number complications inside. The hand-wound Calibre AP 2855 movement powers the perpetual calendar with a moonphase. There is also the lever on the left side of the case for the gongs of the minute repeater. Pull it down, then active it, and you get a little harmony of gongs and bells that tell you the time if read (listened to) properly.

The case is done in either 18k white gold or platinum, with a variety of finishes on the case. The sides are polished, while the bezel is brushed and the dial is satin finished. The cathedral style hands and hour markers are in rose gold. One of the best features is the font style of the number markers which looks classic at first, but has a unique modern flair if you observe them carefully. Nice to know Audemars Piguet is not exclusively about the Royal Oak line, nice work AP.

Tiffany & Co. Mark Perpetual Calendar TriRetrograde Chronograph Watch

Filed under: Timepieces / Watches


Here is a limited edition (16 pieces only) watch from Tiffany & Co. that shows how well their partnership with the Swatch Group is working out (where they now get movements). The Mark Perpetual Calendar TriRetrograde Chronograph watch is an advancement on the previous Mark T-57 TriRetrograde Chronograph. This new model has a movement that not only maintains the retrograde chronograph complication, but also adds a perpetual calendar complete with a moon phase indicator in the mix. Despite the many pieces of information displayed on the dial, Tiffany & Co. designers keep the watch face looking attractive.

The Tiffany & Co. Mark line has always been about modern classics, and this new model is no different. While the Mark T-57 line has been all about sport, the main Mark line is a sober approach at handsome looks. The case is available in 18k yellow or rose gold, with well done squared pushers. The partially guilloche engraved dial helps to frame the Roman numerals around the face, while aperture window placement on the dial is laid out according to the movement specifications below. This design was never intended to be a symmetrical looking watch, and rather, it excels at appearing like a gentleman's tool valuing function and luxury above anything else. Hopefully Tiffany will eventually release more than 16 of these watches.

Chronoswiss Perpetual Calendar CH 1720 Watch Line

Filed under: Timepieces / Watches


With a refreshing return to simplicity among perpetual calendar watches, Chronoswiss releases a new addition to the luxury calendar watch family with the Perpetual Calendar line. The CH 1720 -1723 are finely shaped 40mm watches in styled with traditional pocket watches in mind. If it were not for the attached straight lugs and smaller size, you'd never know this was anything but a beautiful classic pocket watch. For this new traditional timepiece, Chronoswiss uses a base in-house made caliber C. 127 movement with a Dubois-Dépraz sourced 5800 C calendar module.

The many functions of a perpetual calendar complication are neatly laid out on the dial using three subsidiary dials and one aperture window that features the moonphase. Notice that the top subdial used to display the month is set out to display the months for a total of four years. The reason for this is to indicate if the current year is a leap year which adds a day to February. A perpetual calendar is defined as one that is able to compensate for leap years and thus only rarely needs adjusting (that is unless you forget to wind it).

Like most Chronoswiss watches, the "onion" crown is larger than you'd expect for the watch size, but allows for comfortable winding of the movement. The layout design is perfect from a legibility standpoint with the blued steel hands being the perfect width and length. The case is available in five different materials: there is a limited edition platinum model, a steel model, and 18k yellow, rose, or white gold models. The dial face is a machine polished sterling silver in an off-white color finish. Securing the watch is an alligator strap. I'd have to say that this is one of the most desirable Chronoswiss watches I've seen in a while, with flawless execution of the Roman numeral hour markers, and a sublimely attractive yet simple design.
