This GMT dual time zone watch in covert black stainless steel finish is one of our latest watches and has a high performance quartz Ronda 515.24 movement housed in a robust 300m water resistant casing which makes the watch ideally suited for swimming, snorkelling, water sports and scuba diving although as a GMT watch the bezel is not designed specifically for diving applications.
The concept behind GMT watches is very clever not because they are in any way particularly complex but because the technology behind them is so incredibly simple. On a conventional with the hour hand is designed to travel around the dial over a 12 hour period, all that is needed to create a GMT watch is to add a second hour hand which travels around the dial in 24 hours instead of the usual 12 and then to add an additional 24-hour time scale to a bezel hence the reason most GMT watches at quick glance look like divers watches. How you use the watch could not be easier because the 24-hour hand circles the dial once a day instead of twice with a normal hour hand, its tip indicates the corresponding hour and because it’s operating on the 24 hour timescale there can be no confusion between a.m. and p.m.
We initially produced these watches for airline and navy pilots because the watch enables them to see the time in two different time zones. Because this watch uses a quartz movement it is ideally suitable for people who require a hassle free low maintenance watch and who tend to travel frequently or work regularly in two timezones.
The watch measures 46mm including the crown and 43mm excluding the crown and uses the the same 20mm NATO strap as many of our military divers watches.
