Internal bezel aside, this Aquascaphe Dual Crown collection distinguishes itself through the inclusion of dual crowns. The crown at 4 o’clock is dedicated to precise time adjustments, while the non-screw-down crown at 2 o’clock controls the inner bezel, enabling seamless underwater operation. Both crowns flaunt an engraved cross-hatch design which is a nod to the original super compressor watches of the 60s.
