Patek Philippe’s New Rose Gold Annual Calendar Regulator

It wasn’t until 2012 that Patek Philippe made a regulator style watch where the hours, minutes, and seconds were displayed on three different dials. Based on the clocks found in watchmakers’ workshops, which were used to set other watches and had to be accurate, Regulators are typically simple affairs, but Patek wouldn’t be Patek without adding a bit more to the watch.

The Patek Regulator added an annual calendar as well as more high-tech movement components—a Pulsomax escapement, a Spiromax balance spring, and a Gyromax balance. Seven years later, Patek is revisiting that watch.

Based on the 5235, the new watch adds an R, for the rose gold case (not for “Regulator’) and the two-tone dial. The dial features graphite and ebony black with a vertical satin finish, which, when combined with the rose gold, makes the watch warm and inviting. It comes with a black alligator leather strap with a rose gold prong buckle.

The 5235R features a 31-260 REG QA caliber and displays hours, minutes, seconds, and an annual calendar with discs for month, day, and date. The watch is water resistant up to 30 meters and has a 48 hour power reserve. The movement of the watch is visible through the case back. You can see the automatic winding via a gold micro-rotor. You’ll also note the silicone technology.

The Gold Rose Regulator measures 40.5mm wide and 10mm thick and retails for USD$51,830.
