Owners talk.

“

Owners and reviewers widely praise the Omega Speedmaster Calibre 321 Chronograph 38 6mm for its superior pusher feel, refined movement finishing, and sharp dial clarity, with many appreciating its vintage look and feel, comfortable bracelet, and robust finishing that holds up exceptionally well to daily wear. Some owners note a slight misalignment of the "Swiss Made" text on the dial. Accuracy varies, with one owner reporting +20 seconds/day and another receiving a unit running 70 seconds slow per day, while others find it less accurate than the 3861. The Omega Speedmaster Calibre 321 Chronograph 38 6mm is also noted for its significant price, limited availability, and lack of modern features like hacking and anti-magnetism, though its historical significance and craftsmanship are appreciated. Overall, owners and reviewers rate the Omega Speedmaster Calibre 321 Chronograph 38 6mm highly for its exceptional finishing and vintage appeal, despite its premium price point.
