GMT Submarine / Naval Crew Divers Watch 500m Tritium

The MWC "Naval Crew" range of Military Divers models are one of MWC's latest heavyduty ranges.

There are two models with stainless steel finish, the other in hidden antiglare PVD steel, the watches use red T100 tritium GTLS tubes which makes them superior to alternative watches because they can successfully preserve night vision on the deck of a ship or in a submarine.

Submarines are normally 'rigged for red' to allow the use of the periscope at night, dusk and dawn without interference from the bright light in the control room.

When coming to periscope depth a submarine is at its most vulnerable to collision, and red light gives the operator additional time as his eyes do not need to adjust to night conditions.

These watches were ordered by submarine crews specifically for this purpose.

These watches are extremely robust: they have sapphire crystal, in addition to being suitable for mixed gas diving at extreme depths thanks to the water resistance of 500 m (1,650 feet) rating, they also have a strap wider than 24mm (the most military dive watches use a 20mm strap) and a scratchresistant ceramic bezel that is easier to grasp in extreme cold conditions.

They are also equipped with a high quality Ronda Swiss GMT 515.24H movement with a hacking function to allow for synchronization.

All MWC 500m (1,650ft) models are equipped with a helium escape valve.
