The Tudor North Flag might not get as much love as its Black Bay siblings, but for those in the know, it’s one of the most technically interesting sport watches the brand has released. This 40mm steel tool watch was the first to feature Tudor’s in-house MT5621 movement and brought a power reserve indicator to the dial—rare for the brand. It has a rugged, almost scientific aesthetic, built with the same exploratory spirit as the British North Greenland Expedition that inspired its name. If you're after a Tudor that flies a bit under the radar, the North Flag is a solid choice.
