Crafted in 18k white gold, the case maintains the Aquanaut’s rounded octagonal profile while introducing a heavier, more substantial feel on the wrist. The khaki green dial offers a distinctive tone within the collection, structured with embossed detailing and luminous Arabic numerals for optimal readability. Inside, the automatic Caliber CH 28-520 C drives the chronograph system, utilizing a vertical clutch to ensure smooth engagement and reduced wear over time. The flyback function allows instantaneous reset and restart, enhancing practical usability. Beating at 4 Hz, the movement delivers consistent performance with a power reserve of up to 55 hours. Through the sapphire case back, the movement reveals hand-finished components, polished edges, and an engraved gold rotor. The watch is water-resistant to 120 meters and paired with a matching composite strap that reinforces both comfort and durability.

Rather than relying on bold contrast, this reference achieves its impact through material depth and tonal balance. The combination of white gold and muted green creates a more understated luxury, appealing to collectors who value mechanical integrity paired with a refined, less overtly sporty aesthetic.
