Tudor North Flag shows its automatic caliber on the ground
With Tudor, the watch manufacturer Rolex wanted to create a brand that was cheaper but just as reliable as a Rolex. For a long time, the Tudor company, which was founded in 1926, received its housing and movements from its sister company. This only changed completely with the new Tudor North Flag Ref. M91210N line. The company uses its in-house automatic caliber MT5621 in the Tudor North Flag line. The wearer of a North Flag can see the caliber through a viewing window. It is located at the bottom of the North Flag.
