Debuted at SIHH 2020 is this new and truly awesome (in both price and design) aviation watch from Omega designed in collaboration with Airbus’ private jet division. ACJ stands for “Airbus Corporate Jets” and this arm of the French airplane company produces jetliners for usually 20-50 passengers for the ultra-wealthy, corporations, or even governments. ACJ chose to partner with Omega replica watches, and this rather interesting Omega Speedmaster moon-phase Chronograph watch is the result.
The Omega Speedmaster moon-phase Chronograph Master Chronometer begins with a new movement that is the in-house-made Omega caliber 9904 movement. Building on the caliber 9300 series the 9904 adds more than just a moon-phase complication and a diverse way to indicate the date. It is thus realistic Omega claims that on close inspection you can see the picture of a footprint on it (from the NASA Apollo missions).
The 9904 movement is made up of 368 parts and includes the time, 12-hour chronograph, date, and new moon-phase indicator with a photo-realistic representation of the moon. The movement is now fully METAS certified and a “Master Chronometer” (debuted with the Omega Globemaster), which implies a few things. In comparison to my other watches, it is light and sits flatly around the wrist which makes me extremely comfortable to put on. First is that the movement has all the Omega-made anti-magnetic parts. Of course, the movement is as well a Co-Axial Escapement. The moon phase is said to require adjustments once each 10 years or so, and the new date indicator uses a pointer-style hand in the left subsidiary dial and helps balance out the two subdials which each have two hands. On top of that, the METAS certification (more on that here) requires a lot of durability and performance out of not just the movements however the movements cased up in the complete watch, thus the overall set of “assurances” for the consumer are much higher than several thing like COSC Chronometer certification alone.
Presented in a 41mm stainless steel case and bracelet, the surface alternates brushed and polished finishes. On the case-back, a sapphire crystal glass with the official Olympic logo reveals the Master Co-Axial 8500 movement. Although this is not one of Omega’s newly METAS-certified calibres (procedure described in this article), the COSC-certified movement is anti-magnetic to fields of up 15,000 Gauss and water-resistant to 150 meters, in keeping with the collection’s origins as replica watches.
