HydroConquest GMT Automatic 41 mm
The 41 mm stainless steel case houses a Swiss automatic GMT movement that beats at 25,200 vibrations per hour and stores up to 72 hours of power reserve. A sunray green dial sits under scratch-resistant sapphire crystal with a uni-directional rotating bezel topped by a black ceramic ring. The watch is water-resistant to 300 metres and comes on a green nylon NATO strap.
Upgrade from a standard three-hand diver
The central GMT hand and 24-hour flange scale add true second-time-zone tracking without a second crown. Luminous snowflake hands and applied markers keep dive-legible readability in low light. A screw-down crown and solid caseback maintain 300-metre water resistance while the calibre L844 extends autonomy to three full days off the wrist.
Fits a 21 mm lug width and 12.90 mm case profile
The green NATO strap threads through fixed lugs and secures with a signed stainless steel buckle, leaving spring-bar changes tool-free. No additional bracelet links are required for sizing. The 41 mm diameter suits wrists that prefer a mid-size sports watch rather than an oversized case.

Questions about this item
What lug width does the 41 mm case need for a replacement strap?
The case takes a 21 mm strap, which matches the supplied green nylon NATO.
How do I set the GMT hand independently, and what step is often missed?
Unscrew the crown, pull to the first position, and turn the GMT hand in one-hour jumps; the step people miss is leaving the crown unscrewed after setting.
When will the L844 movement need a service interval?
Longines recommends a full service every 4 to 5 years to keep the 72-hour power reserve and 300 m water resistance.
