Description: 2016 Speedmaster Moonphase. The Moonphase watches from omega have been around since the 80s and over the years have gone through many overhauls. This one in particular is a 44.25mm case with a thickness of 17mm. The twin-barrel Design gives the watch a longer power reserve of 60 hours, hence the larger case. The case is in great condition and is believed to be unpolished.
