Is the Longines HydroConquest GMT a true GMT?

Yes. The L844 movement has an independently adjustable local hour hand, so you can jump time zones without stopping the watch. The 24-hour hand tracks home time.

How does it compare with the standard HydroConquest?

It adds the GMT complication, the in-house L844 movement with a 72-hour reserve and a ceramic bezel. The standard three-hand HydroConquest uses a different movement and has a shorter reserve.

Can I swim and dive with it?

Yes. It is rated to 300m with a screw-down crown and caseback, which covers swimming, snorkeling and recreational diving.

How does it compare with a Tudor Black Bay GMT?

The Longines costs less and has a similar in-house GMT setup, but the Tudor has better finishing, a more refined bracelet and stronger resale. The Longines is thinner and lighter on the wrist.

What is the power reserve?

About 72 hours, so it keeps running through a weekend off the wrist.

Does it have a display caseback?

No. The caseback is solid steel, so the movement is not visible.

About the Longines HydroConquest GMT 41mm

The Longines HydroConquest GMT is a 41 mm automatic dive-style watch with a green dial. The case and bracelet are stainless steel with a brushed and polished finish. The bezel is ceramic, rotates in one direction only, and has a Super-LumiNova capsule on the triangle. The bracelet closes with a push-button deployment clasp.

The dial has luminous gold-tone hands and stick hour markers, with minute markers around the outer rim. A central GMT hand tracks a second time zone, and the date window sits at 3 o'clock. The watch uses Swiss automatic movement, Longines Caliber L844, with a 72-hour power reserve.

The crown screws down and the case back is solid and screw-down. The sapphire crystal is scratch resistant and has a multi-layer anti-reflective coating on both sides. The watch is water resistant to 300 meters (990 feet).
