HydroConquest GMT Automatic 41 mm
This 41 mm stainless-steel dive watch runs on the Swiss automatic caliber L844 beating at 25,200 vibrations per hour with a 72-hour power reserve. A sunray brown dial sits under scratch-resistant sapphire crystal and is framed by a uni-directional rotating bezel with a brown ceramic insert. Yellow gold-tone luminescent hands and applied indices ensure legibility in low light.
Suited to divers and travellers needing a second
The central GMT hand tracks a 24-hour scale on the dial edge while a bordered date window sits at 3 o'clock. Buyers who want an integrated metal bracelet or a thinner case profile should look elsewhere. The 12.90 mm thickness and 21 mm nylon NATO strap dictate a specific wrist presence that not every wearer prefers.
Build-ready with 300 m water resistance
The solid caseback bears Longines' winged hourglass emblem and the watch is rated to 300 metres or 1,000 feet. A beige nylon NATO strap with a signed stainless-steel buckle ships fitted, freeing the owner from sourcing a separate band. No additional tools are required to adjust the strap length.

Questions about this item
What size spring bars or tools do I need to change the 21 mm beige NATO strap on the L3.790.4.66.2?
The strap uses standard 21 mm spring bars; a fork-type spring-bar tool is all that is required to swap it.
Will the uni-directional rotating bezel on this 41 mm HydroConquest still align cleanly if I wear it over a 12 mm wetsuit cuff?
The bezel rotates independently of the crown and has 120 clicks, so it can be operated with gloved fingers and stays aligned at any depth.
How can I verify the caliber L844 is keeping time within spec after I set the GMT hand to a second time zone?
Compare the watch to a reliable time source over several days; the movement is rated for typical automatic accuracy and the 24-hour scale lets you confirm the GMT hand tracks correctly.
