5 Forward 6 Back, can you remember where you sent your watch?
I used to take mine to Breitling in London, but they moved to Tunbridge Wells. So next time I took my watch to the 'nearest' dealer - in Northampton. Whereas London either kept my watch until my next trip, or posted it in a box, Northampton returned it in the condition I described. But I suspect that all they did was to send it away - I doubt whether they did the actual work......
