This GMT dual time zone watch in stainless steel finish is one of our latest watches and has a high-performance quartz Ronda 515.24 movement housed in a robust 100m / 330ft water-resistant steel casing which makes the watch suitable for swimming and snorkelling.
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 watch, the hour hand is designed to travel around the dial over a 12 hour period, all that is needed in order to create a GMT watch is to add a second hour hand.
