Made an Watch Makers Eye loupe using a old Camera lens and it plastic casing. Without spending a Penny.

Seems this bezel is pressfitted on the edge of the crystal and watchcase.

Hi, if where my dad's watch I would try and return it to its original state. My advice would be to have an original sized crystal in place. Those bezels are a dress bezel and can brake if forced. The crystal looks like it is pressed over the case, but if it's larger in diameter than the bezel then don't press the bezel over it if it's to tight. Hope this helps

But still your contribution to the industry lives on and on, good stuff. But still you don't have to use it, you can just look at it.

looking at your video the oscilloscope is showing way too much background noise. It improves later in the video we could just barely start to see the signal you need. Was that the microphone that came with the software? I snipped out some images one of them off the software's website and one out of your video. from the website the image that I have for the oscilloscope you will notice there are two separate lines labeled drop threshold and unlocking threshold. these of the signals required for amplitude. The only need one signal for rate which would be the unlocking. then in your image you're only using the unlocking and it's on the wrong part of the waveform. this is why you have a rate and the amplitude is totally wrong. so you really need to get rid of the background noise reduce that down to almost nothing. Then need to find the other threshold line I'm guessing it's in the center right now as it looks like there may be a line their. That line needs to come up to where the other one is and the other one needs to drop down and trigger off the unlocking. once the signals correct or much nicer than it is now triggering lines where there supposed to be things will look much nicer and the correct amplitude will be there.

not a lot of information out there at least not that I'm finding. I found a couple articles on each of the watches. I did find a 4S15 sheet not the same one you requested but it's in the same family hopefully it's helpful. Then I did find the the other one working on my computer no idea where it came from? As conveniently looking online I didn't find one. https://reference.grail-watch.com/family/seiko-4s/ https://www.tapatalk.com/groups/seikoholics/inside-the-seiko-caliber-5740c-high-beat-t1188.html 263_Seiko4S15A.pdf 5740C-Lord-Marvel-36000.pdf

I just bought one of these, 20 something years in as a professional, used either the lathe and collets or pinvices that take Schaublin P4.5 collets (have a bunch) all this time, but given the number of chronos I do figured the auction price will pay for itself in a year then I get 2 decades of free use till I retire. Then back on Ebay. I'll start it at 1 buck in 2040, haha.

The slippery Soviet is still putting in a strong performance.

Thank you so much, going to read it carefully. I actually tried, but I was to afraid to break the spring. So I went back to square 1, disassemble and reassemble everything and after that balance was still not working, so I thought to put it in the demagnetizer and it worked!! I demagnetized the entire movement and now the balance is working; Unfortunately I still do not have a timegrapher (hopefully Xmas) to see how it’s running.. but I’m happy. now I took an old case and put the movement there. I guess restoring a case is whole other story ? Thank you all for the support - I left some pictures

Well having serviced many ladies watches the smallest being the size of a marble maybe I qualify to have a go at the diagnosis. Back to basics remove the power from the watch and then remove the balance and the fork, Now test the train for freedom by applying half a turn on the main spring, if the train wheels turn freely wit a little back spin when stopping the train is deemed free. Now fit the fork and put one to two turns on the mainspring and check the fork snaps back and forth when moved if that's ok then re fit the balance after check, Inspect the pivots are intact, Check the balance spring is flat and the coils are free and not touching and not sticking together when oscillating, Thats for starters.

The finished results. Way too nice for me to think of ruining it with clutter, tools, 3d printers, microscopes.. nasty solvents.. abrasives, paints.. you get the picture. ? Smith and Rodger, for those of you unfamiliar with Glasgow, and who's wax polish, wire wool and wax wood repair touch up sticks I used. They do a full range of French polish supplies, shellac, 0000 wire wool and so forth. This is one of those little businesses that has been around forever (well 1877 to be more precise). Its not a place you would stumble upon by accident, but well worth a visit (or a web order) if you are in need of anything related to old wooden items. Wooden clock cases or traditional furniture for example. I have no affiliation with them, other than the fact that they are friendly and very helpful and extremely knowledgable.

The other day I spotted a writing desk on Freegle which I thought might make a nice watch repair work bench. Touching up a few minor blemishes with a spot of acrylic colour. I'm currently using an ugly old chipboard computer desk, so even of the Freegle item was not in perfect shape, it couldn't be any worse cosmetically at least, so I enquired and was offered it. A little baby oil was used to remove some sticky residue from Sellotape and other random stickers. When we got there to take a look, there were some pretty obvious bodges holding the thing together and I was swithering about whether to leave it, but what the heck, it was free. As they say, you should never look the proverbial gift horse in the mouth, so I popped in the back of the car and thanked the previous owner profusely for their generosity. Smith and Rodger wax finish applied to the wood restores the surface and closes up the worst of the dried up finish. A couple of days back, having sprayed it with copious amounts of antibacterial spray and further more, having left the thing out in the shed to "de-covid" I attacked it with a screwdriver, removed the bizarre array of ironmongery holding it together and took a good hard look at it. It seemed to be all there (although arguably, the same might not be true of me of course). The "leftovers". Sitting on its polished top, "legs akimbo" as it were, on a couple of garden chair cushions to protect its finish, I dismantled all of its "undercarriage", and set too with sandpaper, chisels, wood-glue and clamps. I did resort to using one screw to glue and screw one of the spacer blocks, which had split corner to corner. The rest was restored with glue only, back to its original state (if you ignore all of the screw holes added by the previous owner). The leather writing surface was removed and re-glued as it had come adrift. The only problem is, I've made such a good job of it, my wife has decided it will look very nice in the study. Oh well, back to the old computer desk, I guess. You know what they say, no good deed goes unpunished. ?

Hi Watchmakers is correct, If you are in the states places to look are Jules Borel, Esslingers, Otto Frei and I am sure there will be others. If you are just starting out the attached publication is worth a read. 1033305402_TZIllustratedGlossary(1).pdf

Unless you fancy a challenge it's worth looking at the websites of the usual parts suppliers first. The Resources page you'll find a link to at the head of this forum is a good place to start. I can see for instance Cousins has both male and female stem parts listed. I'm sure other suppliers closer to your neck of the woods might be able to oblige too. Also a good tip to a newbie is not to focus exclusively on the movement model you're specifically dealing but be aware of models in the same family. In your case http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&ETA_2375 will list other members of the family. Often you'll find that parts are listed against the first member of the family ... so that's the ETA 2370 in your case. A quick ebay search on 'eta 2370 stem' brings up for instance https://www.ebay.com/itm/ETA-2370-watch-movement-part-404-female-split-stem/132105059577 With these breadcrumbs I'll let you take over...! ?
