Slimline Manufacture Perpetual Calendar, unique piece

Treat yourself to the only Frederique Constant Slimline Manufacture Perpetual Calendar watch with a solitary Roman XV on the dial.

This watch that is unique in the world was created to mark the 15th anniversary of the WorldTempus site belonging to the founder of the Fine Watch Club, who now wishes to enable a club member to enjoy owning it. This private collector’s item has never been worn.

The Frederique Constant Slimline Manufacture Perpetual Calendar has serious appeal. It is the least expensive perpetual calendar equipped with a manufacture movement on the market and it is now offered by the Fine Watch Club in one unique edition.

Specially commissioned to celebrate our 15th anniversary, last year, it is the only piece on which the slender baton hour marker at 3 o’clock has been replaced by “XV” in Roman numerals.

The movement of the Frederique Constant Slimline Manufacture Perpetual Calendar is capable of taking into account the variation in the lengths of months across a four-year cycle and can therefore cope not only with the differing lengths of months with 28, 30 and 31 days but also with the 29th day added to the month of February every leap year. The corresponding indications are displayed clearly on the dial in three sub-counters: one for the day, one for the date and a combined one (at 12 o’clock) for the month and the year in the four-year cycle. A separate moon phase counter at 6 o’clock shows the lunar cycle and is coupled with the perpetual calendar display, meaning that no date correction is needed until 1st March 2100. The indications can nevertheless be adjusted if required using pushers hidden into the side of the case.

This exclusive unique piece features a 42mm steel case with a brown leather strap. It is equipped with a self-winding movement (Caliber FC-775) with a 38-hour power reserve
