The Ulysse Nardin Marine Chronograph Annual Calendar is the 2016 steel reference 1533-150/43. Its calendar tracks 30- and 31-day months but not February, so it needs a correction once a year after February. GPHG’s model record lists a 43 mm case, 100 m water resistance and a 52-hour power reserve.
How the annual calendar works
An annual calendar distinguishes months with 30 days from those with 31. February is the exception: the mechanism does not account for its shorter length, so the date must be corrected once each year after February. GPHG says this model’s calendar can be adjusted in both directions.
GPHG describes the mechanism as a development of the simple calendar used in caliber UN-118, with three additional wheels for the annual-calendar system. That is the explanation in the model record, rather than a report from an independent movement examination.
How it compares with other calendar types
- Simple calendar: GPHG says it needs five manual corrections a year.
- Annual calendar: It handles 30- and 31-day months automatically, requiring correction after February.
- Perpetual calendar: GPHG says it needs no correction before 2100.

How to distinguish it from the Marine Torpilleur Annual Chronograph
The similarly named Marine Torpilleur Annual Chronograph is a separate, later watch, not another name for the 2016 Marine Chronograph Annual Calendar. The official Ulysse Nardin listing identifies it as reference 1533-320LE-0A-175/1A and describes a 44 mm case, caliber UN-153 and 53-hour power reserve. Those specifications belong to that Torpilleur reference and should not be attributed to 1533-150/43.
