The Tudor North Flag derives its name and design inspiration from the British North Greenland Expedition in the early 1950s, in which members of the expedition team wore circa-1952 Tudor Oyster Prince models. These “tool watches” were instrumental in carrying out this exploratory mission to some of the earth’s harshest climatic conditions. The North Flag owes some of its “scientific equipment” look to these early watches: a satin-brushed steel case (40 mm in diameter) with ergonomic curves, highlighted by a bezel composed of matte ceramic on one side and brushed steel on the other, along with a conical winding crown that screws down for a 100-meter water resistance. The caseback features a sapphire window through which one can view the movement, automatic Caliber MT5621, which also happens to be the brand’s first in-house-made movement.
