Tudor Grantour 42MM Chrono Fly-Back (Ref. 20550N)

Inspired by the adrenaline of motorsport and crafted with Swiss precision, the Tudor Grantour Chrono Fly-Back 42MM (Ref. 20550N) is built for those who live life in high gear. Its bold 42mm case is sculpted in polished and satin-finished stainless steel, offering a commanding wrist presence with a refined edge.

The black dial features contrasting sub-dials, red accents, and applied hour markers for a look that’s both athletic and elegant. Central to its function is the fly-back chronograph—allowing instant reset and restart of the stopwatch mechanism, ideal for timing laps with precision and ease.

Powered by a self-winding mechanical movement, the Grantour Fly-Back delivers reliable performance under pressure, with a 46-hour power reserve. The fixed bezel, engraved with a tachymeter scale, adds both visual impact and practical function for speed measurement.

Finished with a sporty yet classic three-link bracelet, this timepiece is a tribute to Tudor’s racing heritage and mechanical innovation. It’s perfect for drivers, dreamers, and anyone who appreciates timing—and style—with split-second accuracy.
