Product Overview

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.

01.

Adventure-Proof Bezel

The Frontier GMT’s stainless steel bezel insert is machined for toughness, not decoration. Its highly scratch-resistant surface is finished with a brushed sunray texture that catches the light without sacrificing durability. Black numerals and markings are set in reverse relief, ensuring legibility stays uncompromised.

02.

Tracks Two Timezones

The mechanical, self-winding Miyota 9075 movement allows for accurately tracking two different timezones simultaneously. The traveler GMT functionality grants the ability to adjust the local time via the crown without affecting the 24 hour hand or stopping the watch. Every movement is regulated in-house to maintain an accuracy tolerance of +/-5 seconds per day.

03.

Built from Hardened Steel

Constructed from 316L stainless steel and reinforced by a hardness coating, the Strat-o-timer is built to tackle adventure head-on. The signature cushion case features a blend of brushed and polished finishes that highlight the subtle curvature of the case. Each surface meets at a precisely defined edge that emphasizes the case architecture.

04.

All-Brushed Bracelet

Built to perform day after day and engineered for long-term comfort, the bracelet is designed like a proper tool. The iconic 7-link bracelet is equipped to the Frontier GMT in brushed stainless steel. Its rugged, refined look seamlessly merges the case and bracelet in a way that feels durable and deliberate. Designed to be worn, not worried about.

05.

Light Fades. Legibility Stays.

The Frontier GMT relies on Swiss Super-LumiNova® to stay legible even after nightfall. BGW9 luminous material fills the deep reservoir of each hour marker and is precisely applied to every hand. It emits a crisp blue glow in darkness, but maintains a clean white appearance in full daylight.

06.

Micro-Adjust Clasp

The 316L stainless steel bracelet features a concealed, tool-free system for on-the-go micro-adjustments. The clasp has been carefully engineered with 9 levels of fine-tuning to ensure the perfect fit on a broad spectrum of wrist sizes. While being worn, all the clasp’s mechanics stay hidden out of view to preserve the bracelet’s refined and uniform look.

Just buy it

"The Jack Mason Frontier Alpine doesn't disappoint. A true traveler's GMT, with build quality that is nothing short of impressive. It feels like a genuinely well-engineered travel watch rather than just another GMT with an attractive dial. The bracelet is one of the best in the business. No sharp edges, excellent articulation, and an on-the-fly microadjustment system that makes it a pleasure to wear. My only wish? That Jack Mason offered this watch in a 42mm case. Otherwise, it's hard to find much to complain about."

Eye Catching GMT!

"My Strat-O-Timer Frontier GMT Alpine garners the most compliments of all my watches! It’s no wonder people stop me in coffee shops, etc. to ask me about this watch, it’s a real eye catcher! I love wearing it and already it gets the most wrist time of my collection. Like all Jack Mason watches (BTW, I own five of them) its quality is apparent when you examine it and especially when you first hold it in your hand. The case and bracelet (I really like the classy look and comfort of the 7-link bracelet) are beautifully finished with obvious attention to detail. The bezel moves smoothly with a distinctive click at each detent reassuring me it will not accidentally move out of position on its own once set. And with the Miyota 9075 movement it gives me the traveler GMT functionality typically only found in more expensive watches making it a real value. The Frontier has a rugged, yet refined, appearance which, with the brushed bezel and polished case, looks every bit the GMT tool watch that also looks great with a sport jacket and jeans."

"What a beautiful piece of watch it is! Sturdy, high-quality, and absolutely gorgeous on the wrist. The Jack Mason Strato has a fantastic design and feels solid and well-made. Very impressed with this timepiece!"

— Tamim A. (5/5)

Great watch

"I’m really happy with this watch. I bought it to be my go-to international travel watch, and it’s been great so far. It’s rugged and keeps excellent time. Plus the “flyer” GMT function that is so useful when traveling. I took it on Tour du Mont Blanc, and it was totally up to the rigors of a 100 mile mountain trek."

— Christopher S. (5/5)

My Stolen JM watch

"Recently received my new watch which would have been my fourth but unfortunately my adult son was at the house when the packaged arrived and he loved the look the placement of the JM emblem and asked if this could be his Christmas present. So now I am back down to 3 JM watches. Nothing but quality all around."

Good watch, nice price

"Good watch, nice price"

— Dag M. (5/5)

"Fantastic product. Better than the pictures display of the watch, its not overly shiny or flashy. It could be a dress watch or a outdoor sport watch. Full spectrum of utility plus the true GMT function which I prefer. I have one in black and it has been working flawlessly, +/- 3 seconds over the past 3 years. Highly recommend."
