Strat-o-timer Frontier GMT: Alpine
Lugs stay on wrists from about 6.25 in (lug-to-lug rule of thumb)
From Jack Mason
The Strat-o-timer Frontier GMT is the ultimate traveler’s tool. Inside the watch is the Miyota 9075 GMT movement that features an independently jumping local hour hand, regulated in-house to +/- 5 seconds per day. The brushed, stainless steel bezel is engineered for toughness and pairs well with the fully brushed 7-link bracelet. The dial and handset both feature Grade A BGW9 to ensure long lasting glow in low light environments. With a vision of becoming a legacy brand in our home state of Texas, the Strat-o-timer is assembled, and the movement regulated, in the USA.
