Housed in a round 41.5mm case crafted from stainless steel and 18kt rose gold, reference 331.22.42.51.01.001 measures 16.5mm in thickness and features a transparent case back that reveals the movement within. A fixed bezel frames an anti-reflective, scratch-resistant sapphire crystal, while water resistance is rated to 100 metres / 330 feet.
The black dial is paired with a brown calfskin leather strap secured by a push-button folding clasp, lending the watch a warm, two-tone character. At the heart of the piece beats an automatic chronometer movement with Co-Axial technology and a chronograph complication, COSC certified for precision.
Reference 331.22.42.51.01.001 draws its design language from the original 1957 Speedmaster, translating that heritage into a contemporary 41.5mm package with the refinement of rose gold detailing.
