The Aquanaut Luce collection for women welcomes a new, useful, and easy-to-use complication: the patented Annual Calendar, a complete day/date/month calendar that requires only one manual correction per year, at the end of February. The Manufacture thus completes its range of complicated ladies’ watches with a non-gem-set model.

The iconic design of the rounded octagonal rose gold case and bezel is enhanced by the contrast between the polished and satin finishes. The blue-gray dial and Aquanaut-patterned bracelet reinforce the watch’s contemporary sport-chic style.
