Drawing from the original 1957 Speedmaster design, this 41.5mm round case is crafted from stainless steel and 18k yellow gold and measures 16.5mm thick. The fixed bezel and transparent case back complete a profile that honors the model's storied motorsport roots, while water resistance to 100m/330ft adds everyday practicality.
The silver dial is protected by an anti-reflective, scratch-resistant sapphire crystal, keeping the chronograph display clearly legible under any light. Inside, the Co-Axial automatic movement carries COSC chronometer certification, attesting to its precision across a range of conditions.
A matching stainless steel and 18k yellow gold bracelet with a brushed and polished finish secures via a push-button folding clasp, delivering a two-tone look that complements the watch's classic silhouette. Reference 331.20.42.51.02.001 represents a well-appointed chapter in the long Speedmaster lineage.
