A series produced in very few pieces and already entirely allocated. We keep it in the catalog as a reference for the model.
The Longines Hydroconquest L3.788.4.09.9 is part of the Hydroconquest collection. It is the Longines diver: a unidirectional rotating bezel, serious water resistance and a design that works out of the water too. This reference has a 42 mm stainless steel and ceramic bezel case, a green dial, an automatic movement.
The dial
The dial is green.
Case, crystal and strap
The round stainless steel and ceramic bezel case measures 42 mm. The crystal is sapphire. Water resistant to 30 bar.
The movement
The movement is automatic. It winds on the wrist through normal arm movement; if it stops beyond the reserve, wind it from the crown and reset the time.

Can it be worn in water?
