  • TUDOR reintroduced the Northflag featuring an integrated stainless steel bracelet design.

  • Monobloc luminous ceramic hour markers pair with an angled 24-hour rehaut.

TUDOR has doubled-down on its expedition push with the release of the new Tudor Northflag (AUD$7,780, USD$5,525). It follows in the footsteps of the recently released Pelagos FXD GMT, Ranger, and other utility pieces that have helped usher in a new era for the Swiss brand, focusing even more heavily on the outdoors.

The British North Greenland Expedition of the 1950s and the Rolex Tudor Oyster Prince first established this expedition idea, but if we fast-forward some 60 years later, it was the TUDOR “North Flag” (two-words) that launched at Baselworld in 2015 (ref. 91210N) and set a milestone as the first model with an in-house movement, taking visual cues from the Tudor Ranger II. Discontinued in 2021, the new Tudor Northflag revives this lineage, targeting current demand for integrated bracelet travel watches.

One look at the spec sheet and it all looks promising. Measuring 40mm in diameter, 48.8mm lug-to-lug (down from 50mm), and 12.7mm in thickness (down from 13.3mm), the 316L stainless steel case houses the Master Chronometer-certified Manufacture Calibre MT5652-U. Delivering an accuracy of 0/+5 seconds per day alongside 15,000 gauss anti-magnetic protection, the model brings serious technical credentials to the table that will surely grab the attention of a few Rolex Explorer II and Grand Seiko Evolution 9 customers at this price-point.

The original reference TUDOR Northflag was ahead of its time, launching just before the market’s obsession with integrated steel sport watches peaked. It seems this update transforms what was once an eccentric experiment into a technical flagship, but what that means for the Black Bay Pro, only time will tell. By incorporating an integrated bracelet with modern micro-adjustment hardware alongside METAS-grade movement architecture, the design should offer both daily utility for frequent travellers and tool watch collectors alike. Let’s take a closer look!

Dial Layout and Case Geometry

The updated design relies heavily on the sorts of integrated geometry that’s become popular in recent years. But it’s not like TUDOR has followed the trend here, as it maintains the continuous lines inspired by the 1973 Ranger II. It does so with an elevated touch, especially in the highlights where the 40mm 316L stainless steel case’s satin-brushed surfaces are contrasted by polished chamfers running along the top of the lugs and fixed bezel.

Notice how the cone-shaped, screw-down winding crown combines satin-brushing and bead-blasting, complete with the relief TUDOR shield emblem.

On the reverse, an open case back with a domed sapphire crystal reveals the movement. Flip the watch back over and the matte black dial introduces structural depth through a 45-degree angled rehaut housing a 24-hour graduation scale. Hour markers are constructed from monobloc luminous ceramic containing Grade A Swiss Super-LumiNova, providing high-contrast daytime visibility. Meanwhile, the handset incorporates an arrow-shaped 24-hour hand, an arrow hour hand, a baton minute hand, and an angular central seconds hand.

We love the distinctive yellow touches on the dial and how they tie the piece to the historical polar expedition and even the power reserve indicator of the discontinued model. Note the date aperture sits at 3 o’clock, synchronised with the local hour hand, and the power reserve indicator at 9 o’clock has been removed.

Rounding out the construction, and connecting directly to the 12mm lug, the two-link stainless steel integrated bracelet matches the case finishing with satin brushing and polished link chamfers. The bracelet utilises the brand’s tool-free “T-fit” rapid adjustment clasp, providing an 8mm extension range across five set positions. Ceramic ball bearings within the clasp assembly ensure a smooth closure.

What Powers the New TUDOR Northflag?

The new TUDOR Northflag shares its internals with the Pelagos FXD GMT. That means a manufacture calibre MT5652-U is found under the caseback, incorporating its GMT architecture directly into the movement mainplate rather than utilising an add-on module. This is part of the reason the brand has managed to squeeze all of these functions into a case that measures just 12.7mm think, the same as the FXD.

Operating at a frequency of 28,800 beats per hour (4 Hz), the self-winding movement features a non-magnetic silicon balance spring suspended under a rigid traversing bridge with two-point anchoring. Visual finishing includes an openworked tungsten monobloc rotor, laser-grooved radial decorations, and alternating sand-blasted and polished surfaces across the mainplate and bridges.

Built to Master Chronometer specifications, the movement boasts impressive credentials, especially for a watch at this price point. Certified by COSC (-4/+6 seconds uncased) and then further verified by METAS standards (0/+5 seconds daily fully cased) within the new TUDOR manufacture in Le Locle, it provides true flyer GMT functionality via a jumping local hour hand with rapid date correction and stop-seconds precision. The architecture offers complete high-gauss anti-magnetism up to 15,000 gauss alongside a weekend-proof 65-hour power reserve.

The Editor’s Take

The Northflag fixes one of the TUDOR’s most intriguing historical omissions. When discontinued in 2021, the reference was arguably ahead of its time, launching just before the market’s obsession with integrated steel sport watches.

Whether that obsession still carries today is the only questionmark for the new reference, but by equipping the revived silhouette with METAS Master Chronometer certification and an integrated flyer GMT complication, the brand has created a distinct alternative to mainstream vintage-inspired divers.

They’ve also priced it right. While the AUD$7,780 price-tag might put the Northflag in a higher price bracket than standard Black Bay options, it’s more competitive than many of the high-end alternatives from within the Rolex catelogue, and is more technically accomplished than similarly price pieces from some of the biggest mid-range watch brands on the market. It’s a great choice for collectors and regular travellers who love the angular, non-traditional styling, and heritage that comes with it.
