Jack Mason Strat-o-timer GMT: Magnolia
Product Overview
The Strat-o-timer GMT celebrates one of the most iconic watches in history. Housing the Miyota 9075 automatic GMT movement, the Strat-o-timer marks the beginning of a new era of GMTs that features a jumping local hour hand. The bezel features a ceramic insert with Superluminova markings. 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.
Two Time Champion
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.
Distinct Case Shape
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.
USA Assembled & Regulated
Every watch is carefully assembled by hand in the United States of America. During the final inspection, the movement is then tested and regulated in-house by Jack Mason to an accuracy tolerance of +/-5 seconds per day. This procedure guarantees a level of precision and reliability that reflects the Jack Mason standard of excellence.
Legible In Low Light
To preserve crucial legibility in all environments, Swiss Super-LumiNova® is featured abundantly on the Strat-o-timer. The bezel, handset, and indices are highlighted by BGW9 luminescent material. This brilliant substance emits a bright glow when immersed in darkness, but appears white in daylight.
Quick-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.

To keep your watch performing at its best, we recommend avoiding strong impacts, extreme temperatures, and prolonged exposure to moisture unless your watch is designed for water activities. After exposure to salt water, rinse the watch gently with fresh water and dry with a soft cloth.
For mechanical watches, regular wear helps keep the movement running smoothly. If the watch is not worn often, manual winding may be needed depending on the model. Quartz watches may require battery replacement over time.
Leather straps should be kept away from excessive water and humidity to preserve their appearance and longevity.
Because care recommendations can vary by brand and model, please refer to the manufacturer manual included with your watch for detailed operating instructions, water resistance guidelines, and service intervals.
