Corum Romulus Perpetual Calendar Watch, Limited Edition Of 25

Corum has introduced a highly limited perpetual calendar in its classical Romulus watch collection.  Offered in an edition of 25 pieces, the Romulus Perpetual Calendar features a polished 41mm red gold case, a brushed hand-engraved Roman numeral bezel, and a dial decorated with sun-pattern guilloche.  The perpetual calendar displays--which show day, date, month, leap year and phases of the moon--are clearly organized around the dial center, and apertures in the day and date subdials reveal elements of the complex underlying mechanism.

A sapphire crystal window in the caseback reveals an intricate hand-engraved CO-183 automatic movement.  Each element of the bridges and rotor are refined with a delicate scrolling pattern; the rotor also features the Corum brand signature in relief.  The balance wheel alternates at a pace of 18,000 beats per hour, and power reserve of the mainspring barrel is 45 hours.  

The Corum Romulus Perpetual Calendar watch is completed by a crocodile strap, and an 18K red gold buckle which is engraved with the Corum logo.  Water resistance is rated at 30 meters.
