Not every OMEGA Speedmaster Moonwatch is automatic. OMEGA’s manual for reference 310.32.42.50.04.001 identifies its Calibre 3861 as manual-winding; the manufacturer’s January 2026 announcement also names Calibre 3861 for two new black-and-white Moonwatch Professional models but does not describe their winding type in the cited release. Check the exact reference before assuming a watch is automatic.
What does “automatic” mean for a Moonwatch?
An automatic watch winds itself as the wearer moves, using a rotor. A manual-winding watch must be wound by hand. “Master Chronometer” describes a certification, not a winding method, so the wording in a product title does not establish whether a particular Moonwatch is automatic.
For the 42 mm stainless-steel Moonwatch on a rubber strap, reference 310.32.42.50.04.001, OMEGA’s user manual specifies manual winding and Calibre 3861. The January 2026 announcement says its two new black-and-white Moonwatch Professional models also use Calibre 3861, but does not state their winding type in the release. Do not infer that every Moonwatch configuration is automatic—or that every configuration has the same specifications—from the collection name alone.
What OMEGA announced in January 2026
OMEGA’s January 13, 2026 release describes two 42 mm Speedmaster Moonwatch Professional versions with an inverted black-and-white dial: one in stainless steel and one in 18K Moonshine Gold. Both are named with the Co-Axial Master Chronometer Calibre 3861. The release describes the certification in terms of precision, performance and magnetic resistance, and states a five-year warranty for these models.

The 2024 white-dial Moonwatch release describes a different reference with a black anodized aluminium bezel, rather than the ceramic bezel specified for the January 2026 black-and-white models. Bezel material therefore needs to be checked by reference as well.
Quick Recap
What to verify before buying
- Match the reference number on the listing to OMEGA’s product information or manual.
- Confirm whether the watch is manual-winding or automatic from documentation for that reference; do not rely on “Moonwatch” or “Master Chronometer” alone.
- Check the case material, bezel, crystal, and bracelet or strap against the precise configuration you want.
- For the warranty, confirm applicable terms for your purchase date and market. OMEGA’s five-year statement is for the January 2026 launch models.
- Check regional OMEGA availability and the seller’s authorization directly. Current price, stock, and marketplace seller status are not established by the cited materials.
