About the Omega Speedmaster Calibre 321
The Calibre 321 is the original movement architecture that made the Omega Speedmaster famous, featuring a column-wheel chronograph mechanism and lateral clutch that Omega first introduced in the Speedmaster in the 1950s and that went to the Moon on the wrists of Apollo astronauts. Omega reintroduced the Calibre 321 in the Speedmaster Heritage line, hand-assembling the movement using techniques faithful to the original, making it one of the most sought-after Omega complications of the modern era. Across the collection, buyers will find the movement housed in a range of precious and non-precious cases, from everyday-wearable stainless steel to investment-grade platinum and Canopus gold, each paired with the iconic black dial and the symmetrical sub-register layout synonymous with the Moonwatch lineage.
What to Look For
When shopping Calibre 321 references, case material is the primary value driver: stainless steel examples like 311.30.40.30.01.001 offer the most accessible entry point, while platinum and Canopus gold references command significant premiums and represent the top tier of the range. Case size also varies meaningfully across the collection, with the 38.6 mm references appealing to buyers who prefer a more refined fit and the 42 mm and 39.7 mm cases suiting those who want closer alignment with the classic Moonwatch dimensions; condition, box, papers, and bracelet or strap originality all influence pricing.
