The Seiko 6309-7040 diver’s watch is one of my favourite watches. I have worked on many of them before, and have owned several myself. When my friend Ed got in touch a few months ago about a project involving a large number of 6309s and a box of spare movements, donor watches and other parts I was of course very interested indeed.
Ed and I met up and we went through all the watches and movements on my timegrapher to get an idea of the health of each individual item, and decide the best course of action.
Unfortunately due to the magnitude of this project I have not had the discipline to take enough photos to do a detailed walk through of the work, it is so easy to forget when you get stuck in.
I do however have some photos, so I thought I would publish them to give you an idea of some of the work involved. After all it is not often you see so many 6309s in one place!
Here is a photo of the project once completed:
