Scratch-resistant sapphire crystal protects the black dial that's enhanced by luminous baton and Arabic numeral hour markers and hands, with a flash of yellow on the second’s hand, finished with a date window at 3 o'clock and a power reserve indicator at 9 o'clock.Water resistant to 100m, this striking watch is powered by a Manufacture Tudor MT5621 self-winding mechanical movement with a bidirectional rotor system and a power reserve of approximately 70 hours. The North Flag is one of the first TUDOR models to be fitted with a Tudor “Manufacture” movement and has been developed ever since to continually exceed expectations in prestigious watch design.
