Questions
Before you buy.
What movement does the Frontier GMT use?
The Miyota 9075 — a mechanical, self-winding GMT movement with an independently jumping local hour hand. Every movement is individually regulated by American watchmakers to ±5 seconds per day.
How many timezones can it track?
The Frontier GMT tracks two timezones simultaneously. The main hands track local time; the orange GMT hand tracks a second timezone on the 24-hour bezel. Local time can be adjusted independently without stopping the watch.
Is it really water resistant to 200 meters?
Yes. Each watch is rated to 20ATM / 200m, with a screw-down crown and double-sealed sapphire caseback.
What bracelet options are available?
The Frontier GMT is available with a 3-Link stainless steel bracelet. The 7-Link is currently sold out. All bracelets feature a tool-free micro-adjustment clasp.
What is the return policy?
Jack Mason offers free unlimited returns. Pre-orders are estimated to ship February 27.
Where is the watch assembled?
The Strat-o-timer Frontier GMT is assembled in the USA by American watchmakers, with every movement regulated in-house.
