The Tudor Northflag GMT Watch is the 2026 successor to the 2015 North Flag, and it arrives with a clearer brief: keep the angular, exploration-ready silhouette, add a true GMT function, and trim the proportions. According to the reference material, the watch is part of Tudor’s permanent collection, available exclusively through Tudor boutiques, and priced at CHF 4,500, EUR 5,050 or USD 5,525. For buyers who follow both the original and its aftermarket, the more practical question is what changed, what stayed, and when a well-executed alternative might appear. Based on our experience with the earlier North Flag, a faithful Tudor Replica watch of this new reference is a realistic near-term expectation, though no confirmed production timeline exists.
From North Flag to Northflag: What the 2026 Model Changes
The original North Flag was first presented in 2015 and discontinued in 2021, after six years without updates or new variants. Its mechanical significance was straightforward: it was the first Tudor fitted with a manufacture movement, calibre MT5621, and the first Tudor movement visible through a sapphire caseback. The 2026 model keeps the name in a single word, Northflag, and keeps the 40mm case diameter, but reduces thickness from 13.4mm to 12.7mm and lug-to-lug from 50mm to 48.8mm.

Those figures do not turn it into a compact sports watch, but they change the wearing experience. The stainless-steel case remains angular and mostly brushed, with 100m water resistance. The black ceramic ring beneath the steel bezel of the first North Flag is gone, replaced by a fixed, brushed and angled bezel. A box-shaped sapphire crystal and a sapphire caseback are retained, and the screw-down crown at 3 o’clock is more traditionally shaped while keeping a subtle element from the original.
Case and finishing details
- Case: 40mm diameter x 12.7mm thickness x 48.8mm lug-to-lug
- Material: stainless steel, brushed with polished accents
- Bezel: fixed, brushed and angled
- Crystal: box-shaped sapphire; caseback with sapphire crystal
- Crown: conical screw-down at 3 o’clock
- Water resistance: 100m
The finishing has also moved. The original North Flag was edgy and utilitarian in its fit and finish; the new Tudor Northflag adds polished bevels on the edge of the bezel and at 6 and 12 o’clock on the case corners. That is a small change in construction terms, but it shifts the watch toward the more resolved look Tudor has applied across its recent lineup.
Dial and GMT Function: More Information, More Clarity
The black dial follows the North Flag layout with strong white and yellow accents, but the functional centerpiece has changed. The original power-reserve indicator at 9 o’clock, shown by a rotating disc, has disappeared. In its place, the fourth hand now serves a true GMT function, finished in yellow with an arrow-shaped tip. The minutes and seconds track steps down from the inner flange to sit closer to the dial’s center, and a fixed 24-hour scale replaces it.
Other visible changes include a yellow central seconds hand with a rectangular luminous tip rather than a trapezoidal one, closer to the Ranger II that inspired the collection. The matte dial has been replaced by a sunray-brushed surface, discreet in most conditions and visible under certain angles. The hours and minutes hands with Super-LumiNova treatment remain visually unchanged, and the date aperture is still at 3 o’clock. Hour markers and numerals are now made from monobloc ceramic containing luminous material, and the Explorer-like typeface remains, with a raised profile that gives the dial more definition.

The trade-off is worth stating plainly. The power-reserve display was directly linked to the significance of the original MT5621 and its 70-hour autonomy, but on an automatic watch it was a fairly specialized indication. A GMT adds a practical function without altering the image or purpose. Despite carrying more information than before, the dial reads more logically, mostly because the display is more symmetrical.
The Calibre MT5652-U and Its Certification
The Tudor Northflag is powered by calibre MT5652-U, a movement already used elsewhere in Tudor’s collection, including the Pelagos FXD GMT and Black Bay GMT family. It is produced by Tudor’s movement partner Kenissi. The automatic calibre runs at 28,800 vibrations per hour and offers 65 hours of power reserve.
| Specification | Detail |
|---|---|
| Calibre | MT5652-U |
| Producer | Kenissi, for Tudor |
| Winding | Automatic |
| Frequency | 28,800 vibrations/hour |
| Power reserve | 65 hours |
| Jewels | 32 |
| Certification | COSC and METAS Master Chronometer |
| Functions | Hours, minutes, seconds, true GMT, date |
As a true GMT movement, the local hour hand can be adjusted independently in one-hour increments while the 24-hour hand continues to indicate home time. The movement combines a variable-inertia balance with a silicon balance spring. It is visible through the fluted-edge caseback, unlike the movements hidden inside most traditional tool watches.
Bracelet, T-Fit and the Ownership Case
The integrated-style steel bracelet uses broad H-shaped links and a mostly brushed finish, preserving the tool-like appearance and the strong connection between watch and bracelet that mattered to the Ranger II-inspired design. The most relevant upgrade is Tudor’s T-Fit clasp, which provides rapid on-the-wrist adjustment with an 8mm adjustment window. It is a small ease-of-life improvement, but an important one for a watch meant to be worn as an everyday sports watch.

For anyone comparing this reference against the broader market, the ownership case rests on three verified points: a manufacture movement with dual certification, a true GMT function, and a case that is thinner and shorter than the 2015 original. The counterpoints are equally clear. The ceramic bezel ring and the power-reserve display are gone, and the watch is boutique-exclusive, which limits retail access.
Availability, Pricing and the Replica Channel
The Tudor Northflag GMT is part of the permanent collection but is available exclusively through Tudor boutiques. The reference is M9140G1A0U-0001. Pricing is CHF 4,500, EUR 5,050 or USD 5,525. For more details, the reference material points to tudorwatch.com.
Boutique exclusivity changes the secondary-market picture. Buyers who cannot access a boutique, or who prefer not to wait, typically turn to the parallel market first. That is where the replica segment becomes relevant. We previously carried a Tudor North Flag execution that met a high standard of external accuracy, and that experience shapes our read on this release. Based on that history, we expect cooperating factories to develop a Tudor Northflag GMT Watch in the same 1:1-oriented category, though no confirmed release date or specification sheet is available at this time
For readers tracking availability, the practical route is to monitor our Top replica watches listings rather than rely on unverified pre-order pages. Any future listing would need to be checked against the verified dimensions above: 40mm diameter, 12.7mm thickness, 48.8mm lug-to-lug, 100m water resistance, and the MT5652-U function set. Items that deviate from those figures should be treated as a different specification.
What to verify before buying any alternative
- Case dimensions match 40mm x 12.7mm x 48.8mm
- True GMT behavior: independent local hour hand in one-hour increments
- 24-hour hand tracks home time independently of the local hour hand
- Date aperture at 3 o’clock
- Fixed 24-hour inner flange, not a rotating bezel
- Bracelet with H-shaped links and a micro-adjust clasp
- Reference M9140G1A0U-0001 used consistently in listings
Risk Notes and What Remains Unconfirmed
Two categories of risk apply here. The first is product risk: the 2026 Northflag removes two signature elements of the 2015 original, the ceramic bezel ring and the power-reserve display, so buyers who valued those details may find the new model less distinctive. The second is channel risk: boutique exclusivity at CHF 4,500, EUR 5,050 or USD 5,525 restricts official supply, and the replica segment operates without official specifications. Any claim of a 1:1 Northflag GMT should be treated as unverified until independent measurement confirms the case, movement behavior and finish.
Nothing in this article should be read as a prediction of future pricing or availability. The verified facts are the 2026 launch, the MT5652-U movement, the 40mm case, the revised proportions, the T-Fit clasp, and the published retail prices. Everything beyond that, including the timing of any alternative version, remains speculative and will be updated if confirmed information becomes available.
