Tudor North Flag: From the 2015 Original to the 2026 Northflag GMT
Tudor North Flag: From the 2015 Original to the 2026 Northflag GMT
The Tudor North Flag is a 40mm steel sports watch with a black dial, yellow accents and an angular integrated case, launched at Baselworld in 2015 as Tudor's first watch with an in-house movement, the MT5621, and a power reserve indicator. Tudor dropped it in 2021 after about six years, to little protest by one account, and brought it back on September 1, 2026 as the Northflag (one word) GMT, reference 9140G1A0U, at $5,525. This page follows both watches: what the original was, why collectors warmed to it after it was gone, what changed in 2026, and what each costs new and pre-owned. Claims are labelled Confirmed (two or more sources agree), Reported (one source), Community (collector opinion) or Uncertain (sources conflict or we could not verify). Prices were read between September 28 and October 31, 2026 and are indicative.

The 2015 original: Tudor's first in-house movement
The North Flag arrived at Baselworld in 2015, the same year Tudor showed its first brand-made movement in the Pelagos. Time+Tide says the North Flag used the MT5621 while the Pelagos got the MT5612. Wristler, SJX and aBlogtoWatch agree the North Flag was Tudor's first watch with a manufacture movement, and Luxury Bazaar adds that it was also Tudor's first power reserve indicator and first exhibition caseback. Confirmed for the in-house movement; the other “firsts” are Reported.
The specification is consistent across Time+Tide, Watches By Timepiece, Wristler and Grailr. The case is 40mm 316L steel with an integrated, angular profile, 100m water resistance and a display caseback. The MT5621 is COSC certified, has a silicon balance spring and runs for about 70 hours. The dial carries a date at 3 o'clock and a yellow power reserve sub-dial. Grailr gives 13.4mm thick and 50mm lug-to-lug, and a steel bezel ring over a black ceramic base. Two references were sold: M91210N-0001 on a steel bracelet and M91210N-0002 on a black leather strap with yellow stitching and a folding clasp. Reported for the reference suffixes: Luxury Bazaar and Grailr agree with each other, but we did not see Tudor's own page for the retired watch.
Launch pricing is soft. A Gear Patrol listing that appeared in a search result gave $3,675 for the steel-bracelet version, and Time and Watches gave about CHF 3,400 on leather and CHF 3,500 on bracelet. We did not open either page, so we treat both as Uncertain. The firmer figure is the end of the run: $3,725 on leather and $3,850 on bracelet, per Luxury Bazaar and Grailr. Our Tudor brand history covers why in-house calibres mattered to the brand as a whole.
Ranger roots and the name
The design is a deliberate throwback. Watches By Timepiece says the North Flag borrows the bold numerals at 12, 6 and 9, the rectangular minute markers, the arrow-shaped yellow hour hand and the yellow-tipped seconds hand from the 1970s Tudor Ranger II. Wristler names the Ranger II ref. 9111 of 1973 as the historical basis for both generations, and Time+Tide adds the 1952 Oyster Prince as an inspiration. Confirmed for the Ranger lineage, Reported for the individual references. For the field-watch family itself, see our Tudor Ranger history.
The name has a story too. Oracle of Time says the watch is named after a 1950s North Greenland expedition, and Wristler links it to the British North Greenland Expedition. Reported. Tudor's expedition connection is real brand history, but we did not trace the detail to Tudor, so we state it only as the sources do.
A cult watch, but not a hit
Was it a hit? The answer depends on the year you ask. SJX (September 2026) says the original was not a commercial success. Time+Tide's retrospective says dealers reported slowing sales after launch, that Tudor treated the model as a one-off, and that the integrated bracelet was controversial. That piece does not describe a cult following; it credits that status to the Pelagos and says only that appreciation for the North Flag grew after it was dropped. Wristler, by contrast, says it has since built a cult following, and Luxury Bazaar says it was overshadowed by the Black Bay and Pelagos, which makes it a good secondhand value. Community on the “cult” label; Confirmed that it was not a Black Bay-scale seller.
It was also not a limited edition. It was a catalogue watch for about six years. Production dates conflict slightly: most sources say 2015 to 2021, while one UK dealer says 2016 to 2020, so we give 2015 to 2021 and mark the end year as Reported. Time+Tide says the discontinuation came about six years after launch with no successor named, and Luxury Bazaar says it was dropped “to little protest.” We found no official reason from Tudor. Oracle of Time suggests Tudor later filled the niche with the Ranger and the Black Bay Pro; that is the author's reading, not Tudor's statement.
What made collectors warm to it later was mostly what it was not: not another Black Bay. A black dial, yellow detail, a power reserve window and an in-house movement at a price close to a Black Bay is a different proposition, and the used market reflects that, as the buying section shows.
The 2026 Northflag GMT
SJX, Time+Tide, aBlogtoWatch, Oracle of Time and Wristler all covered the revival on or around September 1, 2026. They agree on the core facts. The reference is 9140G1A0U, with the full product number M9140G1A0U-0001. The case is 40mm 316L steel, 12.7mm thick, 100m water resistant, with a domed sapphire crystal and display back. The movement is the Tudor MT5652-U, automatic, 4Hz, 65-hour reserve, certified both COSC and METAS Master Chronometer. SJX adds 0/+5 seconds a day and 15,000 gauss resistance. Confirmed.
The watch is a GMT, which the original never was. SJX says it has a fixed 24-hour flange for a second time zone only, with an independently adjustable local hour hand synced with the date. Wristler calls it a true or flyer GMT. Time+Tide describes the black dial with yellow accents, large numerals at 12 and 6, luminous ceramic monobloc hour markers, a 45-degree rehaut with a 24-hour scale and an arrow-shaped yellow GMT hand. What it drops is the power reserve window, the ceramic bezel ring and the strap option; Grailr and Wristler list the bracelet as the only choice, with a T-Fit clasp. Confirmed.
Two things to watch. First, the movement name. The 2026 sources we read all give MT5652-U for this watch, and our Rolex versus Tudor GMT comparison lists the Black Bay GMT as the MT5652, COSC certified, at about 70 hours, so do not treat the two as the same specification. aBlogtoWatch says the new calibre is the one used in the Pelagos FXD GMT, which we have not checked against that page: Reported. Second, the bracelet. Time+Tide calls it a two-link design while our comparison page's table says three links. Sources conflict, so we say only “integrated bracelet.” Our earlier news report is at Tudor North Flag GMT (2026).
Price and availability
The US price is $5,525. SJX and aBlogtoWatch give it, and search listings cite Tudor's own US page for the same figure; we could not open Tudor's page ourselves, so it is Confirmed but not read at the source. Other markets differ: CHF 4,500 (Time+Tide), about €4,990 (Wristler), GBP 4,310 or about $5,550 (Oracle of Time), and one Spanish retailer showed EUR 5,100, out of stock. SJX and Wristler say it is sold through Tudor boutiques only, and aBlogtoWatch says it is not a limited edition. In other words, availability depends on boutique stock rather than a production cap.
Where it sits: the 2026 price is well above the original's final $3,850. For the Rolex GMT-Master II comparison and Black Bay GMT prices, see our Rolex versus Tudor GMT guide. Price movement across the brand is in our 2026 price increases report, which lists Tudor at 5.6 percent.

Buying a Tudor North Flag or Northflag GMT: new and pre-owned
Original, pre-owned. Luxury Bazaar (September 28, 2026) puts the 2026 market value at about $3,500 to $4,000, and says decent leather-strap watches can be found around $3,500. Loupe showed a fair market value of $3,792 as seen in a search result on October 31, 2026, based on sold and active listings; it also showed a $3,575 retail figure that disagrees with the $3,725 and $3,850 final list prices, so we ignore that number. Grailr (October 2026, partly undated) gives $3,000 to $3,800, with bracelets near $3,500. Forum asking prices ran from about $2,200 to $4,700 per a search summary, which we treat as Community data. UK dealers list at about GBP 3,495. Read the realistic US range as about $3,000 to $3,900.
2026 GMT, pre-owned. Luxury Bazaar and Grailr both report about $6,000 on the secondary market, roughly 9 percent over list, and Luxury Bazaar expects it to settle near list within a year; that is a prediction, not a fact. For wider market context, see our secondary market report.
Which to buy? If you want a power reserve window, a leather option and the lower price, the original is the one. If you cross time zones, want METAS testing and a thinner case, and can reach a boutique, the GMT is the new watch. They are different tools. Check the caseback and papers on any original, confirm the reference suffix (-0001 bracelet or -0002 strap), and compare sold rather than asking prices. We found nothing that says the original will appreciate.
Myths and mix-ups, corrected
- “The North Flag was a limited edition.” It was a regular catalogue watch for about six years, 2015 to 2021, and the 2026 GMT is also not limited.
- “The 2026 Northflag is just a re-release.” It is a different watch: a GMT with the MT5652-U Master Chronometer, 65 hours instead of 70, no power reserve window, no strap option and a bracelet-only offering.
- “The North Flag was an instant cult hit.” SJX calls it a commercial miss and Time+Tide reports slowing sales. The enthusiasm is mostly retrospective and, per Time+Tide and Luxury Bazaar, came after it was dropped.
- “Tudor explained why it dropped the original.” We found no official reason. Reviewers say it went away in 2021, and any reason given is the author's reading.
- “The 2026 movement is the same MT5652 as the Black Bay GMT.” Sources give MT5652-U, with METAS Master Chronometer certification and 65 hours. Our comparison page records the Black Bay GMT as MT5652, COSC, about 70 hours.
- “The name is spelled the same.” aBlogtoWatch says the 2026 model is one word, Northflag, while the original was North Flag. We use the one-word form for the 2026 watch only.
