Tag Heuer Monaco V4 Limited Edition Watch - $80,000
It is the timepiece that you never thought Tag Heuer would make - but they did. As a limited edition of just 150 watches the Monaco V4 is a great looking watch that is as fun to watch in operation as it is to show off. Plus, it is the only Tag Heuer watch I know of made from platinum (170 grams of it). Aside from the unique look of the watch and the modern styling, there are two major points of interest in the watch.
First, the watch movement uses a series of transmission belts instead of pinions. The belts are the smallest made anywhere and still have a thin steel wire in them for strength. Basically, instead of smaller gears connecting some of the larger gears, there are the belts that do it. Second is the use of a liner weight for the automatic movement. The idea is meant to resemble a piston in a engine. Instead of an oscillating weight moving around in a circle, the linear weight moves up and down to power the movement. Power is stored in four barrels that are seen in the rear of the watch (hence the V4 name). The power reserve is 52 hours, and the watch is actually very accurate at about plus or minus 4 seconds a day.
The watch also uses mini ball bearings instead of "rubies" that are commonly used in watches for low friction between gears and palettes. Tag Heuer says that the ball bearings provide even less friction than the commonly used synthetic rubies. The watch functions include the time and a power reserve indicator. It is a new style of skeletonized watch, and very Tag Heuer in character. Price is $80,000 for each piece in the limited edition (save for the first piece that is being auctioned off for charity).
