Tudor North Flag Returns as a GMT with Master Chronometer Certification

Introduction to the New Tudor North Flag

The Tudor North Flag was never the most obvious candidate for a comeback, yet here it is, back for a second generation. Originally launched in 2015, the North Flag was a milestone for Tudor as it was the first model to feature an in-house movement, the MT5621. Its distinctive angular design and integrated bracelet set it apart from the more conventional Black Bay and Pelagos lines. Now, Tudor has reimagined the North Flag with a GMT complication, a new Manufacture movement, and Master Chronometer certification, blending nostalgia with modern performance.

Design Heritage and Inspiration

The new North Flag continues the design language of its predecessor, which itself drew inspiration from the 1973 Ranger II and Tudor's expedition heritage. The original North Flag was linked to the British North Greenland Expedition of the 1950s, where Tudor watches were worn under extreme conditions. This new model pays homage to that legacy while adding practical functionality for today's travelers.

GMT Functionality and Dial Details

The yellow 24-hour hand and angled 24-hour scale on the rehaut make reading a second time zone easy without cluttering the dial. The black dial features large Arabic numerals and monobloc luminous ceramic hour markers, enhancing legibility. The date window at 3 o'clock completes the practical layout.

Case and Bracelet Construction

The 40mm case is crafted from 316L stainless steel with a mix of satin-brushed and polished finishes. Unlike the original, the bezel is now fixed, giving a more classic look. The integrated two-link bracelet features polished chamfers and Tudor's T-fit rapid adjustment clasp, allowing for tool-free micro-adjustments up to 8mm—a thoughtful touch for daily wear.

Movement and Certification

At the heart of the new North Flag is the Tudor Manufacture Calibre MT5652-U, an automatic movement with hours, minutes, seconds, date, and GMT functions. It boasts both COSC and METAS Master Chronometer certifications, ensuring precision and reliability. The silicon balance spring and 65-hour power reserve make it 'weekend-proof,' as Tudor describes. A transparent caseback reveals the technical finishing, including an openworked tungsten rotor.
