Can u tell me what the wording "SWISS T < 25" below the 6 0 clock on your new watch the dial means? Something to do with the glass (oops) crystal? or the pressure? Some one told me that these so called divers watches are OK going in the water, but if they go up (altitude) they may go off bang because the watch is designed for pressure not vacuum. The GMT Master was designed for the fly boys not the frogs, so that T <25 may mean don't fly higher than 25,000 feet or 25 kilometers???

Wear the fox hat?

Hey Steve.

The T25 (Tritium) is referring to the lume material used on the markers.On the later models they used luminova.

Both the GMT and Sub have the same case the major difference being the Subs Triplock crown.The crown being designed to withstand water pressure.

As for the vacuum side of things I have no idea,but I think it would not do it as they have worn watches in outer space.
