  1. I'm looking to buy my first staking set and the above came up on a local eBay like site in Sweden (tradera.se). The seller (like me) knows nothing about the tool so the description simply says: "See the pictures". What would be a reasonable maximum price approximately? Thanks for any input on this! Oh, the brand name is BOLEY if it adds anything!?
  2. I could determine that it was the teeth of the clutch and the winding pinion that was frayed, so I'm now waiting for spares. They weren't so bad that I couldn't wind at all, but when enough tension (and not very much) was built up they would slip. This in turn, and this is actually a question, made the crown wheel slip against the ratchet wheel (or so I believe) making the mainspring unwind uncontrollably in a spit second. Anyway, I hope these winding problems will be gone when I've replaced the clutch and the winding pinion. Or what do you think? BTW, the ETA 2824-2 is the only movement I've seen (haven't got a lot of experience) having this "yoke tail" instead of a yoke spring to put tension on the yoke. I can see that there's quite a risk to forget it in the assembly process, especially if it is the first time you service a 2824-2. Anyway, I studied Mark Lovick's assembly video for the ETA 2824-2 prior to putting it together and took careful note of it. I'm now doing my third ETA, calibre 2472. Overall, my impression of the 2824-2 and now 2472 is that they are rather unconventional, at least when it comes to the train of wheels and the keyless works.
  3. Thanks for your input @anilv! So, do you mean that this could affect the re-banking (or whatever it is that I'm seeing on the timing machine)?
  4. Even badly scratched and dented crystals can be polished to look like new. I use the following two techniques: 1. MrOatMan's crystal polishing using the sandpaper method. 2. Tricks and Hacks for Vostok Watches (@8 min 51 sec).
  5. Very useful and perfectly illustrated! I've never serviced a quartz movement so this will come in very handy one day! Thanks!
  6. Just an update! Assembled the watch a couple of weeks ago but couldn't wind it properly manually. After quite a bit of head-scratching, I eventually realized the clutch and winding pinion are intermittently slipping against one another. I haven't had the time to look into it in detail but I suspect that the tension of the yoke spring is too weak, or that the teeth of the clutch and/or the winding pinion are frayed. Anyway, I'll be back with an update on the re-banking problem as soon as the winding problem has been solved.
  7. I've now completed disassembling my ETA calibre 2472 and made a similar picture guide for how to disassemble the date mechanism; ETA 2472 - Disassembling the date mechanism
  8. The following sequence of pictures shows how to disassemble the date mechanism of ETA calibre 2472 and ETA calibre 2474. Previously I posted a sequence of pictures showing how to disassemble the automatic device of ETA calibres 2472 and 2474 as well as ETA calibres 2450 to 2454. You’ll find the post here.
  9. I started out with Vostok calibre 2409 w/o complications. You can get them on eBay for next to nothing. Get "a bag of them" and you'll have plenty of spare parts and will practice a lot of disassembling in the process. If you do start out with this movement you will likely find my "Vostok 2409 Service Walkthrough" useful. The Vostok movements are IMO the best bang for the buck! BTW, just heard from Mark on YT that he's about to review some Vostok Amphibians, and I can't wait for it! The modern-day Amphibians house the Vostok calibres 2415 and 2416 but they are identical to the 2409 but add automatic winding. Anyway, a great and affordable way to learn about watch repair is to enrol on watchrepairlessons.com. The course movement is a pocket watch movement, Unitas calibre 6498 (base movement in many Panerais). The fact that all parts are about 25 % larger than in wristwatch movements makes it easier to handle when you're new. However, a good option for the course is the Unitas calibre 6325, and incidentally, I just recently serviced one of those!
  10. If you’re like me, taking apart you first ETA calibre 2472 and feeling somewhat intimidated after having removed the case back lid looking down on the automatic works, then you will likely appreciate this post. By the way, except for the oscillating weight itself, the automatic winding device is identical for the following calibres: ETA 2450, ETA 2451, ETA 2452, ETA 2453, ETA 2454, ETA 2472, and ETA 2474. My only other experience of ETA’s automatic winding devices comes from calibre 2824-2. So, looking down on the oscillating weight of the ETA 2472 and not seeing a screw holding it attached to the automatic device framework, made me think the parts had somehow been riveted together and probably were inseparable. Having removed and looked at the back of the automatic device framework I could see that the oscillating weight was indeed attached with a screw or at least something that reminded me of a screw. Its slot was very thin, and it sat in a large jewel! No way I was going to try to remove it without knowing for sure it could be done and how it should be done, especially as this watch wasn’t mine but my brother’s who’d trusted it to me for an overhaul. My first thought then was to try to remove all wheels without touching the oscillating weight. After having looked at the device for a good long while, I realized I wouldn’t be able to remove a single wheel before separating the oscillating weight from the framework. So, I decided to be patient (hardest part of watch repairing), put the parts away for now and research the Internet. I Googled “eta 2472 how to remove oscillating weight”. The first hit was “Untitled - OM-Mechanics”, a PDF document. Well, I wasn’t feeling very optimistic but lo and behold, there it was, in full detail! Anyway, the PDF is pretty poorly scanned, and it isn’t all that easy to read the part numbers, so I decided to make my own picture guide for disassembling the automatic device of this ETA calibre 2472, and that’s what follows next: (Eventually, I’ll publish a complete ETA calibre 2472 service picture walkthrough. If interested, you’ll find a link to it in a future post in this thread.)
  11. That movement is a Poljot 2614.2H (not a Vostok). Poljot is considered by many as the most prestigious Russian watch brand. I've serviced three or four of these calibres and the calendar works is a bit fiddly but other than that it's a charm to work with. It's a very robust movement and very much inspired by Rolex calibre 14270. Here's a very charming and interesting article about the Poljot calibre 2614.2h, and here is one of my favourite watches housing it. Keep us updated on the progress!
  12. Good thing we now have a full hour to correct our little mistakes! Whish we'd have a full day (or more) though! Imagine putting a watch together and only having an hour to correct any mistakes we'd made!
  13. Never heard of a "tension right". Did you really mean a "tension ring", or am I missing something?
