Omega has updated its talismanic Speedmaster Moonwatch collection with an updated movement. The brand’s proprietary Master Chronometer certified anti-magnetic movements will power the next generation of models. This move also marks the discontinuation of the Caliber 1861-powered models.

The minute track is now split by 3 divisions thanks to a 3 Hz movement

The new models take inspiration from the 4th generation Moonwatch style, commonly referenced as the ST 105.012, and worn by Apollo 11 astronauts on the moon in 1969. These space-era tributes include the classic asymmetrical case, the step dial, the double bevel caseback, and the famous dot over 90 (the dot over the 90 marking on the tachymeter bezel was a feature of pre-1970 Speedmasters) and a dot diagonal to 70 on the anodized aluminum bezel ring.

The tapered brushed bracelet has a new clasp now

The big news remains the introduction of the Co-Axial Master Chronometer Calibre 3861, which replaces the Caliber 1861.  Calibre 3861 was spotted most recently on the Silver Snoopy Award 50th anniversary edition. The METAS-certified movement has a power reserve of 50 hours and is resistant to magnetic fields reaching 15,000 gauss.

Caliber 3861 is a cam-switched chronograph movement

Caliber 3861 is a 3 Hz movement (21,600 vph) and the minute track is now split by 3 divisions, as opposed to the 5 divisions on previous models. The brushed bracelet is now more tapered and has a five–arched-links-per-row design. It includes a new clasp with a polished Omega logo on a satin-finished cover. The models are also available with fabric straps now.

The 18k Sedna Gold and 18K Canopus gold editions

The regular steel version is available with a classic Hesalite crystal with a closed caseback as well as sapphire crystal with an exhibition caseback. The sapphire crystal version has an applied Omega logo on the dial to differentiate it from the Hesalite model. Besides stainless steel, the new Moonwatch is also available in 18K Sedna gold or 18K Canopus gold.  Prices start from $5,900 for the Hesalite version paired with a fabric strap.
