Hi Cynar, I have a moon watch which I purchased new, from an Omega Boutique, in March 2016, so I guess it may well be a 2015 watch. The instruction manual has printed on the last line of the back page "09/15" which may confirm that it is a 2015 edition?
The number on the bottom of the spine is 1/18. No guarantee this is a 2015 model, but I hope this helps.
