From the retailer listing
Wearing the Longines HydroConquest is a quiet declaration of taste, of discernment, of knowing exactly what you want. A 39 mm ceramic, stainless steel case pairs with a grey dial to striking effect, the L888 self-winding movement ticks away with 72 h of reserve in hand. Water-resistant to 300 m, with serious capability for serious diving. A date display and luminescent hands and indices for low-light legibility. (Reference L3.780.3.78.9 / L37803789).
