Pre-owned/unworn Longines HydroConquest ref L3.783.4.56.6 delivers the classic luxury dive watch aesthetic currently dominating the market with a sleek stainless steel finish, black dial, and matching black bezel. It wouldn't be a proper dive watch without also including a safer unidirectional bezel and water resistance up to 300 meters/1,000 feet. Aside from being a functional dive watch, ref. L3.783.4.56.6 is also widely sought-after as a high-performance timepiece that is both sophisticated and robust. This model features 21mm lugs, durable stainless steel, scratch-resistant AR sapphire crystal, a waterproof screw-in crown, and a dial decorated with Swiss Super-LumiNova. The caliber of the L688 quartz movement is hard to work with inside the case.
