The name North Flag is English and means North Flag. It was chosen because the Tudor North Flag is based on the Tudor Oyster Prince. This clock was worn in 1952 by the members of a British expedition to the north of Greenland, which led to its association with the north and flags. However, thanks to the cheeky modern appearance of the Tudor North Flag, this historical background does not disturb more forward than backward looking people. It merely recalls the long tradition of Tudor as a manufacturer of robust and diving watches. Although the North Flag itself is rather a robust watch, it is still water-resistant up to a depth of 100 m or 330 ft.
The sister of the Rolex
Tudor is a Swiss watch brand that was originally founded in 1926 as Rolex's more affordable sister brand. Tudor watches were initially marketed as robust timekeepers for work. Thanks to this robustness, and possibly also to the name reminiscent of the former British royal family, the brand was chosen by the Royal Navy for the 1952 expedition and made an international name for itself as a watch for researchers and naval soldiers almost as big as its sister Rolex.
