Tudor’s North Flag is back, bringing with it one of the most distinctive designs in the brand’s modern history. First introduced in 2015 as Tudor’s first watch equipped with a movement developed and manufactured in-house, the North Flag now returns with a new-generation update that adds a GMT function and Master Chronometer certification. Its identity remains rooted in Tudor’s history of exploration: the original took its name from the British North Greenland Expedition of the 1950s, when Tudor watches were worn by expedition members for two years on the Greenland ice sheet. The design also draws from the 1973 Ranger II, reflected in the new model’s integrated bracelet, black dial, luminous Arabic numerals and angular hands. 

The 40 mm stainless-steel case combines satin-brushed and polished surfaces and measures 12.7mm in thickness, with a lug-to-lug distance of 48.8 mm. A fixed stainless-steel bezel frames the case, while the screw-down crown contributes to the watch’s 100-meter water resistance.

Powering the new Northflag is the manufacture caliber MT5652-U, a self-winding mechanical movement developed around Tudor’s adaptable movement architecture. It operates at a frequency of 4 Hz, which translates to 28,800 vibrations per hour and employs a variable-inertia balance mechanism coupled with a non-magnetic silicon balance spring. This design ensures a power reserve of 65 hours, as certified by METAS, effectively rendering the movement “weekend-proof.” The Master Chronometer certification goes beyond conventional chronometer testing. The fully assembled watch must maintain a precision of 0/+5 seconds per day and withstand magnetic fields of 15,000 gauss. METAS also independently verifies its water resistance and power reserve. Before receiving the certification, the movement must additionally pass COSC chronometer testing.
