Tudor Grantour watches

The Tudor Grantour was one of the new lines of Tudor's 2009 relaunch, presented under the slogan "Designed for performance. Engineered for elegance." Tudor, registered as a trademark in 1926 on behalf of Rolex founder Hans Wilsdorf, is Rolex's sister company, and both belong to the Hans Wilsdorf Foundation. The Grantour Chronograph arrived alongside the Glamour collection, a year before the Heritage Chrono, which took its inspiration from the 1970s Tudor Montecarlo.

The Grantour Fly-Back is a 42 mm chronograph in steel with a sapphire crystal. A flyback chronograph lets the timing hand be sent straight back to zero, so the next measurement starts at once.

The variants differ by dial and case metal. The 20551N-0001 has a black dial, the 20551N-0006 a white one and the 20551N-0008 a silver one, all in stainless steel on a strap. The 20551N-0003 keeps the black dial but pairs the steel with pink gold.
