Measuring 40.8 mm in diameter and 10.2 mm in thickness, the 5164G-001 is crafted in white gold and features the Aquanaut's signature embossed dial pattern rendered in opaline blue-gray. White gold applied numerals with a white luminescent coating complete the dial, while a sapphire crystal case back and screw-down crown accompany water resistance to 30 m.
Inside beats the self-winding Caliber 26-330 S C FUS, offering local and home time indication across two time zones, day/night displays for both in dedicated apertures, a date coupled to local time by hand, and a sweep seconds function.
The watch is worn on a blue-gray composite material strap secured by a patented fold-over clasp in white gold, maintaining the cohesive tone of the overall design.
