Tudor's in-house GMT caliber produced at the Kenissi manufacture, featuring an independently adjustable jumping local hour hand for practical dual-timezone use. The 28 jewels and 6.23mm height accommodate the additional GMT complication over the base MT5400. COSC certified with a 70-hour power reserve and silicon balance spring, it powers the Black Bay GMT and Black Bay Pro at price points well below comparable Rolex GMT offerings.
