The Girard-Perregaux R&D 01 Motorsports Chronograph (Reference 49930) is a bold 43mm, driver-focused luxury watch released in the mid-2000s, featuring an unconventional left-handed (destro) design with pushers on the left for better wrist ergonomics. Known for high-quality, in-house caliber 033C0 movements and excellent finishing, it blends motorsports aesthetics (like a 24-hour display) with technical innovation. [1, 2, 3, 4, 5]
