Miyota
Miyota's GMT complication caliber built on the 90-series platform, featuring an independently adjustable 24-hour hand for tracking a second time zone. At 28 jewels it has the highest jewel count in the Miyota automatic lineup. The 5.67mm height accommodates the additional GMT wheel train, and the true GMT function with jumping local hour hand makes it a compelling alternative to Swiss GMT movements at a fraction of the cost.

The community take
Owners talk.
Owners and reviewers widely praise the Jack Mason Strat-o-timer GMT for its exceptional value and traveler GMT functionality powered by the Miyota 9075 movement. Specific strengths highlighted include impressive fit and finish, screw-in bracelet pins, on-the-fly adjustment, sapphire crystal front and back, a screw-down crown, and a lumed bezel. The 7-link bracelet, with its micro-adjust buckle offering 9 points of adjustment, is frequently cited as a standout feature, with some owners comparing it favorably to much more expensive watches. Some reviewers note "chubby" hour markers and a potentially plastic bezel insert, though others state it is sapphire. The watch is praised for its comfortable 42mm case and vintage aesthetic. Overall, owners rate the Jack Mason Strat-o-timer GMT highly for its outstanding value and well-executed traveler GMT complication.
