Bought mine in Hong Kong 1992 for £600 in a fit of pique having been denied a holiday due lack of time remaining on passport...
Haven't seriously looked back since.. however, local jewellers in Aberdeen replaced battery in 1996, and moisture entered.. led to a flaw appearing on the lower LCD display. Now I can live with that, so no big deal..
But servicing.. I just wait till one of my mates is heading to Hong Kong, and get them to do it there.. somewhere on the island, not sure quite where. Costs about £50 and right up to Breitling standards, including replacing the seals.. plus done whilst you wait. The LCD will take about £200 to replace mind you.. if I want to do it.
Cost of course includes about an extra £20 in beer for the mate afterwards....
