For so many reasons, this 105.012-63.
First the 105.012 is a fascinating reference to a Speedmaster nerd like me as it was the only confirmed Omega on the moon.
The -63 is interesting as it often came with a SWISS MADE dial with no T's as this one.
The 105.012 is the first Asymmetric case, and the first Professional marked dial.
This particular one came on an ebay sale - I wish I had kept the listing. Poor three photos of a speedmaster, and described as a 1970's omega. No movement pictures, no pictures of the rear, and a 1171 bracelet. It was from the owners family.
I paid 1370 sterling for it and was shocked to see a 321 sitting in it. I knew very little at the time, but I knew it was not from 1970's. It was one of the first watches STS serviced for me and it has been wonderful since.
For me the dial, handset and bezel have all aged contemporaneously and attractively.
The dial is correct, with a high SWISS MADE, AML and Professional marking. The lume is present, and slightly degraded. The body of the dial is solid, very slightly faded, and undamaged. All the printing is complete and undamaged.
The hands look original to the watch, showing gentle degradation and patina that fits with the rest of the watch. They are correct for the reference.
The bezel also fits with the rest of the condition, and faded to an attractive grey - we have to be careful with all the so-called ghost bezels that are unattractive, or even bleached.
The case is sound, clean and only sightly polished.
In summary it is not NOS, it is not even what many might consider a fine example - the bezel is faded, the hands are degraded, the lume is not full - but I do believe it is original, and gently patinated.
It is the watch I reach for instinctively when I let my eye wander through my box, looking for the most pleasing example.
