The name of the Tudor North Flag pays tribute to the British North Greenland Expedition. During their polar mission in the 1950s, members of the expedition wore Tudor watches, relying on their proven performance to withstand extreme conditions. Inspired by this legacy, the Tudor North Flag (M91210N) was launched in 2015, featuring a 41mm integrated case and a black dial with a power reserve indicator at the 9 o'clock position. As the first model to house a Tudor *Manufacture* movement (the MT caliber), it also introduced an open case back to showcase the movement's details. Since 2023, Tudor has progressively equipped new models with *Manufacture* movements certified as Master Chronometers by METAS. This certification standard builds upon the Swiss Official Chronometer Testing Institute (COSC) criteria but imposes even stricter requirements—such as limiting the daily rate variation to between 0 and +5 seconds and ensuring resistance to magnetic fields of up to 15,000 gauss.Best luxury replica watches price at Repwatcheaprice, cheap watches for men and women.
The same applies to the Calibre MT5652-U powering this new model. It features the signature Tudor in-house movement specifications—including a silicon balance spring and a 65-hour power reserve—and was previously utilized in the Pelagos FXD GMT. Compared to the non-METAS certified version, the MT5652-U boasts enhanced decorative details, with the bridges featuring "Master Chronometer" lettering and sunray-brushed finishes. The change in movement caliber brings a shift in the watch's complications: a dual-time function—indicated by a GMT hand reading against a 24-hour scale on the dial's periphery—marks the most significant upgrade for this new North Flag model. Yellow serves as the signature accent color, highlighting key details across the dial; the GMT hand, select hour markers, and the "NORTH FLAG" model name are all rendered in yellow, injecting vibrancy into the otherwise black-and-white dial.
Another change in the new-generation Ranger model concerns the case: it features a 40mm stainless steel case with a thickness of 12.7mm. Compared to its predecessor, the diameter has been reduced by 1mm and the thickness by 0.6mm. In terms of detailing, the case features curved chamfers and is paired with an integrated H-link stainless steel bracelet and a Tudor "T-fit" clasp with a built-in micro-adjustment system—design choices that align it with popular luxury sports watches. Currently, the new Ranger is available exclusively with a stainless steel bracelet; a leather strap option has not yet been reintroduced. Historically, the 2015 Ranger was the first watch to feature a Tudor *Manufacture* (in-house) movement, marking a significant milestone for the brand. While retaining the essence of the original design, the new version replaces the power reserve indicator with a more frequently used GMT function, joining the ranks of the Black Bay GMT, Black Bay Fifty-Eight GMT, Black Bay Pro, and Pelagos FXD GMT to further expand Tudor's GMT lineup.
