  1. You came to the right place with like minded fanatics! Welcome! Sent from my iPad using Tapatalk
  2. Welcome to a great group of like minded old men (probably). We have 2 cats and a dog. Luckily I use a roll top desk for my watches. I dust the Tambour door before I open it and make sure all my parts are in dust cover trays until I’m ready to install them. Also, I have to wash my hands before I start. It is very much like surgery. I may be a bit over compensating, but it works pretty well. Dust trays are relatively cheap. You could use a sheet of tissue paper or similar to cover your work area while you are away. I’ve had watches stop on me only to to open them up days later to pull a very fine hair out of the works. Keep trying. You will find something that works for you and it doesn’t have to cost a mint. Sent from my iPad using Tapatalk
  3. Excellent work!! Sent from my iPad using Tapatalk
  4. Anything is possible. Be sure it is bent and not being kept out of true by a piece of odd debris or possibly some other cause. Be careful and prepared for it to break, as a worst case scenario. Take before and after pics to share, please. Good luck. Sent from my iPad using Tapatalk
  5. We know!!, Or at least have a good idea. Bravo!! Sent from my iPad using Tapatalk
  6. It is acrylic and it is entirely spider webbed in cracks across the entirety of the lens. I want to replace with glass. So I’ll have to be careful with the measurements, so as not to flex the existing lens while using the caliper. Sent from my iPad using Tapatalk
  7. Where do you find these spec sheets? I’ve looked for several models and can’t seem to find them. I obviously don’t know where to look. Sent from my iPad using Tapatalk
  8. The Eterna is going well. But I need a replacement lens. However, I don’t know anything about wrist watch crystals. I have thousands of pocket watch crystals but none are domed like the original on the 1429u. It measures 31.5mm in diameter and 4.5mm high. I checked Cousins and could not find one. Any ideas would be appreciated. Sent from my iPad using Tapatalk
  9. One more question about wrist watches. Specifically the Eterna 1429u I’m working on. I usually work on pocket watches and have collected a sizable collection of NOS replacement lenses. But I don’t know anything about wrist watch crystals. The one I’m trying to replace measures 31.5mm diameter by 4.5mm high. The bottom that fits the frame of the watch measures exactly 13 and 15/16 lignes. I checked Cousins. However, I don’t know the difference between domed, curved, flat bottom etc. Would anyone be willing to educate me a bit on wrist watch lenses/crystals? Sent from my iPad using Tapatalk
  10. Thank you, Anilv. You and Nucejoe have been a great help. I will post the completed work after I get the new mainspring from Cousins and get it back together. I genuinely appreciate the help and added learning you provided. Sent from my iPad using Tapatalk
  11. Thank you, Nucejoe. I wasn’t sure that was the caliber or another reference. Just ordered this mainspring from Cousins. Already disassembled and bathed in the ultrasonic. Cleaning the details and capped jewels. It is in surprisingly excellent shape. Case is a bit dirty but nothing appears un-cleanable. Will post finished photos when I have it back together. Than you sincerely for the education!! Sent from my iPad using Tapatalk
  12. Thank you!! But how did you determine the caliber? Sent from my iPad using Tapatalk
  13. Anyone recognize this Eterna caliber? I have a broken main spring. Sent from my iPad using Tapatalk
  14. I can’t find the original site. I’ve purged my browser history for government spying reasons.... However, here is a pic of one of the “extras” I purchased. I believe you are correct about it being Chinese. Though I do remember the ship-from address to be Japan. Sent from my iPad using Tapatalk
  15. I ordered from the Seiko part site from Japan. Maybe I’m wrong on the price. But not by much. Oh well, it worked. I’ll look more closely next time I order a new part. Sent from my iPad using Tapatalk
