  1. I've returned several of these to life - one after extensive battery leak damage. The circuit can be cleaned and is very robust. The coil is another matter. It's very easy to damage and can't really be fixed. Even the toothbrush work you did may have damaged it if you went over the top of the coil. That said, my first go at servicing a watch was with one of these. There's a technical manual online and a few teardown guides on various forums - look for 7548 teardowns.

  2. Nice work, especially creating your own dial logo. How have you found the ofrei case? I was considering one for my own project and would have paid the extra for the case (compared to the ones straight out of China), but Ofrei's international postage is criminal (around $80US if I remember rightly). Here's mine, also built out of an old pocket watch. Sent from my iPhone using Tapatalk
  3. Some of the advantages are in the summary that you've linked to. I find them nice and stable with a firm grip on the movement and if you line the movement up right you have cut outs for the stem and dial screws. Sent from my iPhone using Tapatalk
  4. I was responding to JDM's suggestion that you print a 7S26 movement holder. They can be a better way of holding a movement while you're working on it that the usual metal movement holder that screws tighter to grip your movement. Here is one holding a Seiko 6309 movement.

  5. Seller Hal0eight on eBay (also known as VTA or VintageTimeAustralia) currently sells a 3D printed movement holder for the Seiko 7S series of movements, as well as other common Seiko movement families. Sent from my iPhone using Tapatalk
  6. Welcome Nobby. Although I live at the opposite end of the world (Tasmania, Australia), my mother comes from the IoW (Shalfleet) and I've spent a little time on the island. Take heart, I'm a low level tinkerer who has certainly made things worse in the past, but I've also completed a number of successful services. Sent from my iPhone using Tapatalk
  7. Cousins is listing the GR2534x as a substitute - 1.05x.115x420x10.5. More expensive (£16.50) than they're selling the GR25341x suggested above (£7.95). They appear to have the same dimensions. Sent from my iPhone using Tapatalk
  8. Take a screwdriver that's slightly too large for the gap in the C. Place it in the gap and twist. The screwdriver will force the gap apart and the clip will lift slightly. You will then be able to pop another screwdriver under the clip and lift it off. Sent from my iPhone using Tapatalk
  9. Hey guys. As Pip said, the Grand Seiko high end sub brand has been around a long time - since the 1960s. Throughout that time they've been high end mechanical and some high end quartz watches. The quality is certainly as good as high quality Swiss stuff. As for the spring drive, it's driven by a mainspring - not a battery and step motor. It does have a quartz element - there is a 'brake' that regulates the movement and this 'brake' is controlled by a circuit (I'm not sure without reading up whether this circuit gets its power direct from the mainspring as it is released or if there is any stored power). Either way, this is very sophisticated technology and in no way comparable to a kinetic watch. Sent from my iPhone using Tapatalk
  10. Welcome from Hobart. I'm curious to see what you stashed away in a box all those years ago. Sent from my iPhone using Tapatalk
  11. Yes, that is probably what is needed. If you have a link to one for sale, that would be great. Sent from my iPhone using Tapatalk
  12. I had one of those for a while. If I'd known it was the "holy grail" I would have asked more when I sold it [emoji2] Like yours, mine had a knock to the crystal - but at around 9 o'clock. Sent from my iPhone using Tapatalk
  13. Well the dial side was a lot trickier than the train side. After a few goes I managed to get it all lined up and working correctly. Unfortunately, there are no signs of life. Using my multimeter the coil tests good, the battery is good, but there are no pulses emitting from the circuit [emoji22] Looks like I'll be keeping my eyes open for a donor 1337 or 1332 from which to salvage the circuit.

  14. I managed to find time today to finish cleaning and rebuilding the gear train today. Everything seems to be working properly with regard to the two magnets between the second and centre wheels. When the second wheel is inserted into the centre wheel there is quite obvious resistance pushing the two wheels apart. Win! Sent from my iPhone using Tapatalk
  15. I'm guessing Stefan is a well known seller of vintage Seiko parts. He's on a couple of the forums under the name Seikochrono or schillachi61. He sells on eBay under the name schillachi61. He often has parts he hasn't listed on eBay so shoot him a message with a specific request. Sent from my iPhone using Tapatalk
