About This Watch:

The Tudor North Flag Ref 91210N was produced from 2015 to 2021 and marked the debut of Tudor’s first in-house COSC-certified Calibre MT5621 movement. With an integrated bracelet design and an exhibition case back showcasing the new movement, the North Flag was designed with the adventurer in mind.

The History: Tudor began to produce watches in 1926 that could be marketed and manufactured as a more affordable timepiece than the Rolex line while still keeping the same standard of dependability that Rolex had become known for. Over the years, the product line grew to include the renowned Oyster Prince and their diver watches, such as the Submariner series. Tudor began producing timepieces for the French Navy in 1956.

The Watch: The Tudor North Flag Ref 91210N features a 40mm brushed stainless steel case with a sapphire crystal and an exhibition case back. The bezel on the North Flag is unique, with a black ceramic ring underneath the brushed stainless steel bezel with a polished chamfer on the underside. The black dial has white lumed hour plots and numerals at the 12 and 6 o’clock positions, with a date window at the 3 o’clock position and a power reserve indicator at the 9 o’clock position. The minute track, seconds hand, and power reserve indicator feature yellow accents. Powered by the in-house COSC-certified Calibre MT5621 movement, the North Flag has a 70-hour power reserve and a water resistance rating of 100 meters.

The Details: This Tudor North Flag Ref 91210N comes on an integrated Tudor stainless steel bracelet with a fold-over clasp. The case, case back, and lugs show some wear, which is visible in the photographs. This timepiece includes the inner and outer boxes, instruction manual, COSC certification, warranty card, document holder, and serial number hang tag.
