"After missing several drops, finally snagged one. This is my second strat (the first a Bluebonnet) and I can’t stop looking at it! Wonderful fit & finish, comfortable, and couldn’t be more pleased. Also have a JM Canton and feel like I’m just starting my collection. Thank you JM!"
"I have owned a number of Rolex GMT's both the 116710 and 126710, which are currently selling for between 14k and 25k on the market as it is virtually impossible to get one at the retail price from a dealer. Even the retail price is well over 10k. The Strat-o-timer is equally as good a watch. Rolex are factory rated at +/-2 sec/24 hr. While rated as factory set at +/-5 sec/24hr, my Strat-o-timer is timing at +2-2 1/2 sec both while on a timer and when worn. Both watches are true GMT, both have ceramic bezels, and I find the crown action virtually as smooth as that found on my current Rolex. While the stainless steel used in both watches is different, it's interesting to know that the stainless steel used by Jack Mason is the same as used by Patek. On top of all that, both come with a 5 year warranty, and unlike the Rolex GMT the Strat-o-timer has an exhibition back with a decorated movement, and also has twice the water resistance as the Rolex. Bottom line, save a whole lot of money and get the Jack Mason if your looking for a GMT watch."
"I had been waiting for lone star to come back in stock! Elation and insta-buy when I got the email. Love it, get asked about it — it’s my Texas watch."
"As a 4th generation Texan (and Dallasite) I can't imagine a watch that personifies Texas pride better than the Strat-O-Timer Lone Star GMT! The finishing touches, the rich colors and the quality craftsmanship are more than apparent once you set eyes on this masterpiece. I love the Texas patriot story this watch conveys and have worn it consistently since buying it in July 2025. My favorite feature is the jump hour complication. Very handy when traveling between time zones. And the navy tropic strap looks great with this watch. Jack Mason is now my go to watch and strap company."
"I had a great time visiting the showroom. They were very welcoming and accommodating. They had every watch to try on and play with. The quality and finishing of the watches is top notch. They took time to explain the manufacturing process and warranty. When the time came, I was able to buy my favorite spec of Strat O Timer. I’m stunned at the deep, rich colors of the ceramic bezel and how it meets the retro boxed sapphire crystal. The dial is beautifully simple and easy to read. I love the small bits of Texas flare that are sprinkled throughout. I have been super impressed!"
"Beautiful watch. Was lucky enough to handle it at the NYC Intersection watch show and my son fell in love with it. Surprised him with it on his birthday three weeks later. He LOVES it!"
"I own 3 Jack Mason watches and love all of them"
"I’ve been eyeing this watch for a while and finally went to the showroom to check in out. Corey was great and after checking out the watch, I couldn’t leave without it! Highly recommend."
"I had high expectations for this watch, after researching it for the past few months. It has definitely delivered on those expectations! Delivery was fast! It’s fit and the overall finish and function are phenomenal for the price! The bracelet and micro adjust definitely punch above their class and I really appreciate the hardness coating. I have worn it the majority of the past 2 weeks and it only gained 12 seconds. This will definitely not be my last Jack Mason. Easily a single brand collection is possible."
"What an amazing GMT watch! So glad I was recommended to this one. The band is amazing the dial is fantastic. Feels great on the wrist. I can’t wait to add more to my collection."
