After selling my lovely Diamond flake before realising what a great movement it has, I could not resist buying another one when it showed up…. This watch was bought on ebay as a non-running watch with a terrible photo. So seeing that lovely dial made me want to service the watch straight away.
At first sight the movement looks very nice.Removing the canon pinion I discover a small disaster zone. A previous watchmaker has tried to fit a new bush for the centre wheel pinion and has used too much force damaging the base plate.I decide to continue on the watch, as these movements are getting hard to find and I think it deserves to be fixed.The old mainspring.Here you can see the top side of the old repair.I start by removing the old bush and then broaching the hole to size so I can fit a new one. The trick is to hit the centre as the old hole is oval.The old repair has already deformed the plate and made it impossible to fit a new jewel. Therefore I have soldered a new bush in place and then machined it to the correct height. I decide on soldering as I do not need to apply any force when fitting the bush. It does not look as pretty as a jewel would, but will do the job.I clean all the parts and start reassembling the movement. The new mainspring.The movement is almost back together and I’m happy to have a free running gear train.Here you can see the setting mechanism before fitting the dial, unfortunately this watch has a broken setting lever spring. If any one has a spare one, please let me know!Here you can see the movement back in the case.Proof of the repair is in the performance 😉Another great looking Diamond Flake ticking like it should.Just love the two toned dial in the sunlight 😉
