Model reference 3581.30.00, excellent condition and complete with all box, papers and links, purchased from an Omega AD around 5 years ago. This is one of my favourite Omega's as most people know on here, it exudes quality and the stunning movement can be seen through the saphire glass back.
As well as being a lot more expensive than most Speedmasters (Retail £5100) it's also considerably bigger at 44.25mm with a beautiful lacquered dial. Sporty/elegant and perfect as a travel watch, Selling for £2500 (Keeping time at +1 sec per day on my wrists)

This is the stock Omega picture followed by my usual fence post shots.
