Housed in an 18k rose gold case measuring 39.9 mm in diameter and 10.9 mm in thickness, the Aquanaut Luce 5261R-001 features a fixed 18k rose gold bezel and a scratch-resistant sapphire crystal that keeps the blue-gray dial in clear view. That dial is embossed with the signature Aquanaut pattern and dressed with gold applied numerals, giving it a distinctive texture that sets it apart from conventional luxury sports watches.
Powering the watch is the self-winding Caliber 26-330 S QA LU, visible through the sapphire crystal exhibition case back. The movement drives an annual calendar display encompassing day, month, date, and moon phases alongside sweep seconds — a compelling array of complications for a watch of this profile. Water resistance is rated to 30 meters.
The watch is paired with a blue-gray composite strap secured by a patented rose gold fold-over clasp, creating a cohesive look from case to wrist. It comes with a store box and a 2-year store warranty.
