Debuting before BaselWorld 2016, this Speedmaster Moonphase Chronograph Master Chronometer uses a new in-house METAS-certified chronograph movement with date and moonphase, based on caliber 9300. The 44.25mm gold case has a ceramic Ceragold tachymeter ring and box sapphire crystal. The metalized mineral crystal moonphase disc is detailed enough to show an astronaut's footprint; ref. 304.63.44.52.02.001 has a silver dial.
