At this level, even today, its a no-brainer.
Non-presentation examples have traded up to $100,000 in the last 5 years.
However I think the valuation of $31,000 given by Bellmans included in the sale would be accurate for non-presentation watch in this condition and at this time.
The question is what premium do we put on an Astronaut watch? The man himself was the command pilot on the A12 mission, so very (very) cool, but not on the moon. And not A11.
We are in more of an enthusiasts market for speedmasters today, rather than speculation. (Which Ironically is when Speculators
should be buying!)
I like speedmasters for the watches, and a little bit the story behind. This watch did not go to the moon, but clearly had a lot of wear by a man who flew around it closer than all but 24 people in all time.
Here is another Gordon (!) oops
@SpeedyPhill thank you! is in 1963 wearing a 2998 and and Acutron. (Photo from NASA)
I would venture the 2998 would be worth more than the Gold on sale.
The real fun might be estimating the value of the accutron
