Drawing on the spirit of the original 1957 Speedmaster, this 41.5mm round case is crafted entirely in 18kt yellow gold, measuring 16.5mm in thickness and finished with a brushed and polished treatment across both the case and the 18kt yellow gold bracelet. A fixed bezel frames the silver dial, while an anti-reflective scratch-resistant sapphire crystal keeps the view clear, and a transparent case back invites a look at the movement within.
Inside beats an automatic Co-Axial chronometer caliber, COSC certified for precision and featuring a chronograph complication. Water resistance is rated to 100 metres / 330 feet, and the bracelet secures via a push-button folding clasp — practical engineering dressed in precious metal.
Reference 331.50.42.51.02.001 occupies a distinguished position in the Speedmaster family, offering the storied '57 silhouette rendered in full yellow gold for those who want the icon in its most opulent expression.
