Patek Philippe is enriching its Aquanaut Luce collection, launched in 2004, as a feminine reinterpretation of the Aquanaut introduced in 1997; with two new delectable offerings.

The first is a non-gemset Aquanaut Luce Ref. 5261R-001 with a new, practical and easy-to-use Annual Calendar. A 39.9 mm-diameter case houses the new self-winding 26 330 S QA LU caliber, with central rotor in 21K gold and the additional Annual Calendar module with moon phases.

Thanks to the inversion of the Annual Calendar module in the case, the calendar indications offer an unusual display compared to other Patek Philippe timepieces equipped with this complication. The date is displayed in an aperture at 6 o'clock, the moon phases in an aperture at 12 o'clock, the day and month in subdials at 3 o'clock and 9 o'clock. The extremely precise moon phase indication deviates only one day in 122 years from the true lunar cycle.

Joining the rest of the Aquanaut Luce collection, which currently ranges from stainless steel, to rose gold, with a variety dial colours, is the Aquanaut Luce Ref. 5268/200R-010, presented with a taupe dial and matching strap and boasting a diamond-set bezel.
