01.

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.

02.

Ceramic Bezel Insert

The Bluebonnet features a ceramic bezel insert that has been precisely engineered for a bold look. The smooth surface adds a touch of luxury and style that won’t fade from UV exposure. This naturally resilient material also makes for a highly scratch-resistant bezel. Additionally, the markings and numerals are set in reverse relief and filled with Swiss Super-LumiNova®.

03.

A Classic Case

The iconic Strat-o-timer cushion case was intentionally designed to be versatile across a variety of wrist sizes. The top side of the case features a brushed finish, while the sides have been mirror polished to accentuate the subtle curvature of the case. Each of these surfaces meet at an elegantly defined edge that emphasizes the case architecture. As an added benefit, the case has been treated with a scratch-resistant coating that protects the watch from minor wear and tear.

04.

Brilliant Blue Glow

To preserve crucial legibility in low-light environments, Swiss Super-LumiNova® is featured abundantly on the Lone Star. The bezel markings and indices contain deep pools of the BGW9 luminescent material. Similarly, it is also carefully applied to the main handset. This brilliant substance emits a blue glow when immersed in darkness, but appears white in daylight.

05.

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.

Jack Mason Strat-O-timer GMT

"JM Strat-O-timer GMT, As an enthusiast and collector of 40 so far watches I think this watch was designed purposely and with thoughtful attention to details, it feels like my Rolex root beer GMT and it looks just as good. I believe that this watch feels like10k dollar on my wrist. Well, done JM team!!"

Julio S. (5/5)

Lovely watch, a few nits

"Overall, this is a beautiful piece. I was impressed by the case proportions, design and finishing. The two things that bug me: One, the movement changes the date almost an hour before midnight. I generally prefer a date to hit around or exactly at midnight. Second, the bracelet is nice for the price point. The end links have a weird finishing they feels cheaper than the rest of the 7 link bracelet. And I think the clasp could have a more modern casing (though the quick adjust is well machined)."

I am excited to have this watch

"Fit, finish, sizing, are all great. The level of detail, awesome. I really appreciated the ease of removing links in the bracelet."

"I really like this watch, even received a few compliments. Nice product I collect watches. , and this one us a beauty. Will be looking forward to something else. Thanks!"

Blue bonnet , strat o timer

"Love the watch, did not like the 7 link bracelet very much so I bought a navy blue strap. I have worn it every day since I bought it and still love it."

Cary F. (5/5)

Absolutely Perfect

"The watch was amazing from the start. Truly a beautiful piece, and fits my profession perfectly. As a pilot in the Air Force, timing is a critical part of what I do. For any pilot, even, without accurate timing, brief times are missed, deadlines are lost, and the effects of lack of proper time keeping are felt by those we’re trying to support. The Bluebonnet color scheme is a perfect mix of blue and silver, the perfect colors for aviation - and the pop of red with the GMT hand adds a nice little flare. I just love wearing this watch, and can’t recommend it enough for anyone who wants to support their friends in Dallas at Jack Mason. Thank you, JM, for serving your country by providing the standard for affordable, high quality, GMT watches. Blue skies and tailwinds :sign_horns:"

Bluebonnet Strat

"I received my Strat-O-Timer GMT Bluebonnet watch a week ago, and I couldn't be happier!  It's absolutely beautiful!  The workmanship rivals my two Rolex Subs, and the color, Bluebonnet, is a real eye-catcher! The blue of the dial face shimmers and catches the light differently depending on the light source and angle- very cool. It came nicely packaged in the distinctive Jack Mason box, which looks like a book, also pretty cool. The watch came wrapped in a thick but transparent protective plastic, and was additionally padded by the leather pouch. All in all, JM took great care to ensure it arrived in pristine condition! The 7-link Jubilee bracelet looks absolutely stunning! The way light reflects off the polished center links highlights the band's exacting workmanship! It's really beautiful! The clasp is very nice; I especially like the side button release mechanism. It's very easy to open, and it feels secure as well. The tool-free micro-adjustment feature made it simple and easy to get a great fit on my wrist. As you can see in the attached photo, it glows brightly with the extensive lumen treatment on the dial, hands, and bezel. This is my first true (“traveler”) GMT. I purchased it after a great deal of research looking for the “perfect” GMT watch in preparation for a trip to Europe this summer. On previous trips there, I had to do mental math to track the time back home, but with the true GMT complication on this watch, it should be easy. I've already confidently recommended Jack Mason to a couple of friends after wearing my Strat-O-Timer GMT and seeing firsthand its build quality. I can't wait for JM to restock their watches this July. I should also add that the Jack Mason team was very helpful in this process; I had to delay shipment since I was out of town. I called, and Corey intercepted it just before it went to the shipper; then he ensured it went out to me when I was finally home to receive it. Excellent customer service!! The bottom line is that this Jack Mason checks all the boxes for me!"

JOHN H. (5/5)

My first JM

"A stunning watch. Much better in person than seen on line, and now I can’t stop looking at it. Very comfortable and easy to use. Quality seems excellent and I’ve already preordered another JM time piece."

Joseph L. (5/5)

Stratotimer Bluebonnet

"I had a lot of expectations for this watch based off what I have seen and heard online. But, WOW the quality and build of this watch is great! The dial and lume are by far my favorite features of the watch other than the fitment!"
