From the retailer listing

Where most watches stop, the Longines HydroConquest is just getting started. A 41 mm stainless steel case pairs with a blue dial to striking effect, inside, the L888 calibre stores 72 h of power reserve. Water-resistant to 300 m, with serious capability for serious diving. Practical date indication and luminescent hands and indices for low-light legibility. The blue rubber strap keeps the sporting character grounded. (Reference L3.781.3.98.9 / L37813989).
