Wow! You remembered all that well.. the 71 Speedmaster I had serviced by Duncan (watchbloke), it was a lovely watch but as I have another of the same reference I sold it to a friend on here.
The Omega Fat Arrow was a beautiful watch but with a few other watch purchases I had to move a few less worn watches on, as you said I tried to sell it here for a while and kept dropping the price but no luck.
I then listed it on eBay at an inflated asking price expecting lower offers, it sat there for quite a long time and I almost forgot about it, then one night it just sold at asking (£2795) to a Japanese buyer through the eBay international posting service.
The 105.003.64 Ed White is a keeper, I didn't think I would own such an early Speedmaster, especially in such original condition, as I said before I was in the right place at the right time and would have kicked myself had I not taken the chance.
One minor regret was missing out on a Heuer Autavia 2446c GMT, it was original and even had the box, papers and purchase receipt but the owner wanted £7k which was fair but expensive when you've just dropped £9.5k on 3 other watches! It still gnaws at me though as I love vintage Heuer's..
