Tudor, North Flag, Steel

Ref: 91210N

The North Flag is fitted with a TUDOR Manufacture movement, visible through a sapphire crystal in the case back and providing impressive autonomy. Its power reserve of approximately 70 hours means that its wearer can, for example, take off the watch on Friday evening and put it on again on Monday morning without having to wind it. Beating to a frequency of 28,800 beats/hour or 4 Hz, the movement is regulated by a variable inertia oscillator with silicon balance spring, held in place by a traversing bridge fixed at both sides to improve resistance to shocks and vibrations. The movement features a bidirectional self-winding system and is certified by the Swiss Official Chronometer Testing Institute (COSC).
