When Tudor launched the original North Flag back in 2015, it served as a monumental milestone for the Genevan brand—introducing their first-ever manufacture movement within an aggressive, integrated-bracelet steel case.
Discontinued in 2021, the cult-favourite tool watch earned a dedicated following among enthusiasts who appreciated its unapologetic angular aesthetics.
Now, Tudor officially resurrects the line with the second-generation Tudor Northflag (Ref. M9140G1A0U-0001), trading the original power reserve indicator for a flyer GMT complication and METAS Master Chronometer certification.
Priced at £4,310, this 40mm release breathes fresh life into Tudor’s polar exploration legacy while maintaining the distinct design DNA that made its predecessor an instant classic.

Ranger II Heritage & Refined Tonneau Geometry
Rooted in Tudor’s historic involvement with the 1952 British North Greenland Expedition and visually inspired by the 1973 Ranger II (Ref. 9111/0), the second-generation Northflag retains its signature tonneau case shape and integrated lug architecture.
However, Tudor refined the proportions across the board. Measuring 40mm in diameter with a trimmed 12.7mm case depth, the 316L stainless steel housing features an interplay of satin-brushed top surfaces and hand-polished bevelled chamfers.
Framing the display is a fixed stainless steel bezel with brushed and polished finishing, while a screw-down cone-shaped crown stamped with the Tudor shield in relief ensures 100 metres (10 ATM) of water resistance.
The case flows directly into an integrated two-link steel bracelet equipped with Tudor’s “T-fit” rapid-adjustment clasp, allowing 8mm of tool-free micro-adjustment across five positions.
Monobloc Ceramic Dial & Integrated Flyer GMT
The most significant evolution on the second-generation Northflag is the removal of the original’s power-reserve display in favour of a true flyer GMT complication—an essential tool for adventurers operating in polar regions where continuous daylight or darkness distort the perception of time.
“By swapping the power reserve for a flyer GMT function and METAS certification, Tudor transforms the Northflag into the ultimate dual-time exploration watch.”
The matte black dial features oversized Arabic numerals at 12 and 6 o’clock alongside rectangular indices crafted from monobloc luminous ceramic filled with Swiss Super-LumiNova.
Surrounding the dial is an angled 45-degree rehaut carrying a 24-hour graduation, providing a clear track for the signature yellow arrow-shaped GMT hand. Electric yellow accents extend to the angular central seconds hand and rehaut markings, delivering vibrant contrast against the dark dial backdrop.
Manufacture Calibre MT5652-U & METAS Precision
Visible through a domed sapphire exhibition caseback—a rarity in Tudor’s tool-watch lineup—beats the manufacture Calibre MT5652-U.
Built with a silicon balance spring and openworked tungsten rotor, this automatic movement carries dual COSC and METAS Master Chronometer certification, guaranteeing accuracy between 0 and +5 seconds per day alongside magnetic resistance up to 15,000 gauss.
