Description from the seller
Up for sale is a classic Longines HydroConquest 41, reference L3.642.4.56.6. This model features a black dial with bold Arabic numerals, an aluminum diving bezel, and a robust 300m water resistance rating. Powering the watch is the Longines L633.5 automatic movement, built on the reliable ETA 2824-2 base.
The watch is in good, honest pre-owned condition. The sapphire crystal is immaculate and the dial is pristine. The stainless steel case and bracelet show typical desk-diving surface marks and light scratches throughout, but retain sharp lines with no dings or deep gouges. It’s sized to a 6.6-inch wrist and comes with one spare link.
Condition: Good pre-owned condition. Honest surface wear and hairlines on the steel bracelet, clasp, and case sides. Crystal is perfectly clean, and the movement runs smoothly. Please refer to the pictures for a better description.
