A Collector's Thoughts
“What a watch!! Just obsessively detailed beautiful piece of art. This watch is the holy grail watch one should aspire to buy!! Made me really happy with the purchase. Ps. This is my one of the 100 Jack Masons I own. I know. Crazy.”
“I own a lot of watches, and I have to say that the Strat is the best value going. The fit and finishing are excellent. The regulation on this watch is flawless. Its accuracy surpasses my Speedmaster! You absolutely can’t go wrong with this watch.”
Zen L. (from Gear Patrol)
“Getting this Strat-O-Timer (in Espresso) on the wrist… I gotta say, it’s impressive. The value and execution blew my expectations away. Very nice stuff. And it’s cool to see the Miyota 9075 GMT movement working its way into more watches, too, and how it can be elevated.”
“The Strat-o-timer is without question above a Seiko for me… the movement alone is so crisp… blows the Seiko 5 GMT out of the water… This is by far going to be my favorite daily watch. It’s got a subtle presence yet robust feel all at the same time. I love this watch… just incredible.”
Miyota 9075: Why It’s a Big Deal
The Miyota 9075 is a self-winding movement with a 42 hour power reserve, 24 jewels, and 28,800vph. Its functions include a GMT with jumping hour, which is functionally identical to a Rolex GMT-Master II and is generally only reserved for watches in higher price ranges.
Regulated for Accuracy
Every Strat-o-timer GMT has been regulated for higher accuracy by Jack Mason. Like a car engine, we take a stock part and maximize its output for better performance.
Assembled in America
We are bringing watch assembly closer to home in order to have full ownership over quality control. This is another step closer to fulfilling our vision in establishing ourselves as a legacy brand that holds generational value.
Extra Quality Control
Jumping Hour Hand
A traveler’s GMT allows for independent adjustment of the time without affecting the GMT hand (which a Caller GMT can’t do). This means a wearer can set the GMT hand to home time and then conveniently adjust the local hour hand while traveling.
