I puchased the watch at a local auction, not the best of places for such a watch but, I did it. By contacting Breitling I found that it was genuine so I was much happier, so happy I decided to have it serviced. The cost was about £900 from Breitling, bit more that the initial quote of £340.
I then saw on Ebay an add from a chap who service such watches for less than £200, I made lots of checks to see if I was going to be conned, I had sufficient confidence to send him the watch. Two days ago I arrived back complete with 28 very clear photographs showing the work carried out. To say I am delighted is an understatement, my watch looks like new and any watch I have in the future will be entrusted to Sean for service. Not only a craftsman but a gentleman.
