Tudor North Flag 40MM Black Dial Steel Bracelet (91210N)
The seller represents this timepiece as being in very good condition. This auction includes the watch and boxes (inner and outer); the papers are not included in the listing.
A discontinued Tudor with real significance in the brand’s modern history. The North Flag was the first Tudor to feature the brand’s manufacture movement, the COSC-certified MT5621, visible through the exhibition caseback. The 40mm steel case, integrated bracelet, matte black dial and yellow accents give it a completely different look from the Black Bay lineup. The power-reserve indicator at 9 o’clock is another feature you rarely see from Tudor. This version of the North Flag was discontinued in 2021 and remains one of Tudor’s more distinctive modern references. Check out my other auctions as well — several great pieces are ending soon.
