  1. Thanks , detailed reply! All makes sense. Don’t worry there will be a short follow on to the first video . Probably within a few days. I will try to see how I can better the reading after getting a datum reading off the TG . Sent from my iPhone using Tapatalk
  2. It’s funny your should post this now. I have just uploaded my latest video on my channel and it’s about the iPhone app vs iOS app. App came off interestingly should we say. Due to some of the feedback and my own curiosity I am going to do one short video test using my lapel mic that I would use for my voice. Also to remove the caseback. I will test first on the timegrapher and then on the app and then compare. Here is my video Sent from my iPhone using Tapatalk
  3. How flat is the hair spring ? Do you have the jewel in the right way around ? I find pin pallet a nightmare. Usually fire up with an oil to the pins on the pallet. Do you have a microscope to examine the pivots to see if one is bent ? Sent from my iPhone using Tapatalk
  4. That’s great. At least you found some things out. Yes Coventry was completely flattened in the bombing. We were a great industrial city and they were after all the factories which had housing built all around them. Sent from my iPhone using Tapatalk
  5. I can’t help in any way as I’ve not worked on pocket watches however a Coventry watch is something I want eventually as I am born and live in Coventry! Part of our heritage. What I will say is there is the Coventry watch museum. It’s only small and open 2 days a week at this time of year but if you get stuck perhaps get in contact with them as for sure they might help you with some advise. Website is easy to find http://www.coventrywatchmuseum.co.uk/ Sent from my iPhone using Tapatalk

  7. Hi, are you sure this is glass? With such a shape it would lend itself to being a flanged acrylic surely? That said I'm sure you've done your research. I have a contact a bit off the radar in the far side of Europe, with the correct numbers for the crystal I could ask if he potentially has this one? Sent from my iPhone using Tapatalk
  8. Thank you sir. Sent from my iPhone using Tapatalk
  9. Thank you sir. Appreciate your reply. I can't get hold of an oscilloscope. I have soldered boards but not small watch boards as this. I will try to join first, if it solves the issue I know I just have to make joins better or pay someone to make good . Thanks Sent from my iPhone using Tapatalk
  10. Thank you sir, reading posts about led watches often symptoms of bad crystal is random leds hence why I wanted to try. As for frequency I chose 32 based on what it says on the underside of the crystal MTQ32A . I couldn't find much googling this. I am hoping that the crystal is not working right for the chip not to decode right. I want to give it a go as the alternative is to find a donor module from another watch. I am actively looking but for the sake of trying its worth having a go. You sir sound like you know what your taking about and I have taken on board your help so thank you for that. As for the bicarbonate your right I just thought it might help. I did also use some white vinegar on a Q tip on the copper contacts which worked well. Battery damage looked quite recent to be honest, I've seen allot worse. Again thank you for taking the time to reply. Appreciated. Sent from my iPhone using Tapatalk
  11. Hi guys I am new here but hope perhaps you can help. I have a collection of 30 or so watches many of which are 70s retro mechanical , jump hour or now led. I just love that genre. Ok so I have a trafalgar led which is a lovely example and near mint contortion apart from the module. I found upon receipt that there had been a battery leak. However not as bad as I have seen and this module still would light. Randomly though. You would press a button and any digit would display at random , sometimes nothing. I cleaned the board with a fibre pen, contact spray and a combination of water and baking soda to null the acidity. I then used my multimeter to test tracks that I could. I found all seemed to be working. I even tweaked the trimmer a little just to see. Sadly all this came to nothing and the module remains faulty. I then researched online and found that this "could " be a bad / faulty oscillator. Common problem in led watches so I am told. I have ordered a replacement one 32mhz in the hope that this might fix it. Questions, To you more experienced , does this sound like a oscillator problem? How easy are they to fit? I have a small tipped soldering iron , not that I'm any good but would try. I read somewhere else of a guy suggesting to leave existing wires soldered to the board and to cut them higher up the stem to remove the old one. Then put the new one next to the short stems and solder together each side. Does this sound plausible? Any advise would be greatly received as I'm really Stuck here and want to at least attempt a fix. The module is a Mostek 03150-04 Sent from my iPhone using Tapatalk
  12. Hello to all. I have just joined this watch forum as it has helped me in the past and now that I have questions I can't find answers to I have decided to join. I have a keen interest in all watches but my genre is 70s retro, mechanical, led and jump hour/ mechanical digital. My collection recently has been growing weekly and I have 30+ watches. I have worked in the abrasives & engineering sector for 20+ years and recently got into restoring watch cases. As I have good ideas on what products to use I though I'd try my hand on a few beaten up Seiko 6119s . I persevered with these stainless cases and surprised myself on my results to the extent of buying more Seikos to hone my skills. Once I have found my way round the forum I hope to post some pictures for your scrutiny and critique. In he mean time I have to post a question on installing a new oscillator into a working led board . Hopefully I can find the right board and get some well needed advise.
