Inspired by elements of mid-century sports cars, the Racing Chronograph 40mm is built to honor both time and speed. The 316L stainless steel case is assembled and tested for water-resistance of up to 100 meters. The navydial complements the design’s sport aesthetic. The brown Italian leather perforated strap is fitted with quick release pins and is compatible with any Jack Mason 18mm strap. This Racing Chronograph 40mm features mineral crystal and a Miyota OS21 movement.
