Tudor North Flag

Tudor North Flag will be introduced as part of Tudor’s 2015 line-up, it has been announced. It will be the first model fitted with movements developed and produced exclusively by and for the brand itself.

Inspired by the perilous journeys to the coldest and most remote regions of the planet, such as the artic, the Tudor North Flag’s movement is regulated by a variable inertia oscillator with silicone balance springs, held in place by a traversing bridge to improve resistance to shocks and vibrations.

The 40 mm case will house Tudor’s in-house calibre MT5621, a self-winding bidirectional mechanism. It has been certified by the Swiss Official Chronometer Testing Institute (COSC), a first for Tudor. The MT5621 calibre will beat to a frequency of 28,800 beats / hour or 4 Hz.

The case of the Tudor North Flag features a satin-finish for a matt effect, whilst the case back is open, showcasing the movement, visible through a sapphire crystal. The strap is available in solid steel, satin finished with polished inter-link surfaces or matt black leather, structured with yellow top-stitching and lining.

It boasts a power reserve of approximately 70 hours. That, means you can take the watch off on Friday evening and slide it back on again on Monday morning, without having to wind it. In addition to its hour, minute and central second functions, it features an instant date display visible through an opening at the 3 o’clock position. While, an indicator of the power reserve is shown in the form of a disc at 9 o’clock.

Having been formed by Hans Wilsdorf in 1926, Tudor formerly sourced their movements from Swiss suppliers. However, the Tudor North Flag marks the first step for the firms plan for greater independence.
