Regulator Annual Calendar 5235/50R

A rose gold annual calendar with a regulator-style dial and a graphite and black finish.

A regulator dial separates the hours and the seconds into two subdials and gives the minutes a long hand of their own. It is modelled on precision clocks used in watchmaking workshops.

This one is rose gold with a two-tone graphite and black dial. Day, date and month are in apertures.

The movement has a Pulsomax escapement and a Spiromax balance spring. The case is 40.5 mm across and 10 mm thick.
