Hi,

This is my first real experience with watch restoration. I've tinkered with movements previously and recently serviced an ETA 2824-2 in my Glycine but that's it. Please excuse any incorrect terminology I use, very new to this and just starting with my horology education. I bought a cheap but working Seiko 5 railway time with a view to dismantling, restoring (to a reasonable level) and servicing it. I'd like to be able to use it by the time i'm done.

It's pretty crusty with seals missing or worn, dusty old lume and doesn't run great but it has at least had some love over the years. Some pictures for the 'journey' so far;

The strip down went fine except for the Second reduction wheel screw which sheared when I tried to remove it. Luckily I managed to remove the thread without causing damage and have a replacement standing by. Please ignore the hair, was used for scale - I was showing off to family as I was so chuffed to remove such a small threaded shaft.

It's currently in bits awaiting a good clean whilst I turn my attention to the crystal and case.

That leads me on to my first question. I couldn't locate a crystal gasket either residing in the case or stuck to the crystal. I'm sure it must have had one in an attempt to be water resistent. The gold coloured tensioning ring is present however. Does anyone know what type of gasket I require to properly seat/seal the crystal? Looking at Cousins in the UK I see the 'I' or 'L' types but i'm unsure and also of the correct way to size the gasket. Any help would be appreciated. Some images below of sizing.

I'll update further as I progress.

Thanks, Ben.

It there is a tension ring there won't be a gasket. Water resistance will be based on surfaces (tight) contact and owner's responsibility.

That's great, thanks for the info.

The reduction wheel screw is a left-hand thread. Basically anything with three lines on it is left-hand threaded.

Just in case you were not aware!

Indeed. I remembered this time but I suppose it's easily overlooked. I think I'll keep a few of those screws spare in future!

    • Hello and welcome to the WRT forum.
    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.    
    • Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything. 
    • Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.
    • I found this string about this problem. I've not gone through it all, but I believe it also mentions making a spring. If not in this string, the info is online.
