Omega Speedmaster Moonphase Co Axial Master Chronometer Moonphase Chronograph 43mm

The Omega Speedmaster Moonphase Co Axial Master Chronometer Moonphase Chronograph 43mm is praised for its beautiful, distinctive design, life-like moonphase indicator with an Apollo 11 landing reference, and Master Chronometer certification. Owners appreciate the detailed moon phase complication, with one noting it uses a 59-day disc. However, the watch's size and thickness, around 44.25mm and 16-17mm respectively, are frequently mentioned as being substantial, with some finding it challenging for dress shirts or noting it wears large. One owner also misses the tactile feel of a manual wind. On balance, owners and reviewers find the Omega Speedmaster Moonphase Co Axial Master Chronometer Moonphase Chronograph 43mm to be a beautiful and comfortable watch, with its unique moon phase complication being a significant draw, despite its considerable size.
