North Flag

In the early 1950's, the members of the British North Greenland Expedition wore Tudor Oyster Prince watches on their wrists while carrying out a series of experiments in the most hostile conditions imaginable on Earth. In this context, their watches, like the rest of their scientific equipment, took on the dimension of a scientific instrument whose reliability was crucial to life on site. It was in this spirit of scientific instrumentation that the hybrid steel ceramic external parts of the Tudor North Flag were created by the Tudor Style Workshop in order to express on the outside the high level of technology and reliability of its movement. This begins with the choice of a case with integrated bracelet, a type of construction with a sophisticated overtone and a highly qualitative feel that requires particularly delicate modelling work in order to attain optimum ergonomics and ideal fluidity of lines. The Tudor North Flag is fitted with Tudor Manufacture movement, visible through a sapphire crystal in the case back.
