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.
