For the privacy of the watch owners, I don't publish the details of servicing the watches on a blog for all to see, but I do send back documentation showing the full service (in pdf form), explaining what was done, and with lots of photos, and if necessary videos as well. Documents can get to 100 pages long for a complex watch or one requiring a lot of extra repairs, and most pages have 2 photos per page. I have been doing this from the beginning, and I think more are starting to do this as time goes by.
There are no secrets in what I do to a watch...but I understand not everyone operates this way, nor would I expect them all to.
I know other (ChrisN for example) takes the same approach. I hope that by being open about what is involved in a service it would encourage other watchmakers to do the same, and that watch owners will have a better understanding of what actually goes into a service/repair that for most I suspect is like a black box. None of us are perfect, and we can all learn from each other - that's why I'm here.
Cheers, Al
