Encased in 42 mm of robust stainless steel, the watch strikes a balance between contemporary presence and comfortable wearability.

This caliber is distinguished by its incorporation of Omega's Co-Axial escapement, a patented innovation designed to reduce friction and improve long-term accuracy and service intervals. Further enhancing its performance, the movement also features a column-wheel chronograph mechanism, widely appreciated by horological connoisseurs for its crisp pusher feel and refined operation, alongside a free-sprung balance for enhanced precision. For collectors, the reference 321.10.42.50.01.001 offers an appealing blend of the iconic Speedmaster silhouette with modern horological advancements.
