The Jack Mason Strat-o-Timer GMT Lone Star Watch ($1149) stands as a masterclass in design and engineering, paying homage to one of horology’s most iconic travel timepieces while carving its own distinct path. Assembled and regulated in the USA, this watch speaks to Jack Mason’s Texas roots and ambition to become a true legacy brand in the Lone Star State.
At its heart, a Miyota 9075 automatic GMT movement delivers a clever traveller’s function, allowing the local hour hand to “jump” forward or backward without interrupting the central 24-hour hand or stopping the watch entirely. This ensures accurate tracking of two time zones simultaneously—ideal for jetsetters and daily commuters alike. Each movement is regulated in-house with impressive precision, targeting an accuracy tolerance of +/-5 seconds per day.
A technical marvel awaits on its exterior as well. The Strat-o-Timer GMT Lone Star’s rotating bezel is crowned by a rare two-piece ceramic insert that seamlessly fuses two separate colours. Where single-piece ceramics can cause unwanted colour bleed, Jack Mason has perfected a process that joins these halves in precise alignment, resulting in a unified design that offers both visual appeal and remarkable scratch-resistance.
Adding to the watch’s legibility, the markings and numerals on the bezel are executed in reverse relief, then filled with Swiss Super-LumiNova® for a striking glow in low-light conditions. This same BGW9 luminescent material also graces the dial’s indices and main handset, emitting a vivid blue hue at night while appearing crisp white by day.
Embodying the classic cushion shape, the Strat-o-Timer case is brushed on top and mirror-polished along its sides, creating an elegant interplay of surfaces that converge with sharply defined edges. Its timeless proportions ensure comfortable wear across a variety of wrist sizes, while a specialized scratch-resistant coating protects against minor nicks and dings that come with everyday adventures.
This resilient exterior is thoughtfully paired with a 316L stainless steel bracelet that features a concealed, tool-free micro-adjustment clasp. Engineered with nine levels of incremental sizing, this ingenious mechanism remains hidden from view when closed, preserving the bracelet’s clean and sophisticated profile.
Every element of the Jack Mason Strat-o-Timer GMT Lone Star Watch represents a dedication to precision, heritage, and modern versatility. From the unique two-tone ceramic bezel to the seamlessly integrated travel GMT functionality, it merges form and function into a meticulously crafted package. Whether you’re traversing continents or simply admiring the artistry beneath its sapphire lens, this striking timepiece makes an indelible statement that bridges the allure of classic watchmaking with the frontier spirit of Texas. For the collector who values both mechanical innovation and timeless design, the Strat-o-Timer GMT Lone Star truly rises above the horizon of contemporary watchmaking.
