  1. I love the rectangular Chayka, I was only looking at those on eBay last night. Looks like we share the same eclectic taste in oddball watches ... and as for the Wittnauer in your other post, that has a great dial......I do not have an ESA9154 driven watch yet, but this ESA9158 Talis and the ESA9157 Montine.... Another Junghan 600 powered watch is on the way, this time a Mathey Doret, sold as non running, but I'm hopeful..... Hopefully, having it's identical Sheffield branded brother, fully working, I should find fault finding a bit easier....
  2. HN Blair appears HERE....he would have been 50 in 1973......
  3. Bit late coming to the party, just found this and downloaded. Many thanks a VERY useful resource...
  4. Surely it's just a Seiko, supplied as a corporate piece for Sony? The same as this 1977 4004 for Motorcraft....
  5. That surely applies to 'original' watches? ..............A 'stainless' one with what is obviously hands and dial (and possibly crown) from a GP one is very non original.....
  6. Had to change to this one........ as I've been playing with this....... The Talis stopped dead but seems to have recovered now it is away from the 'sculpture'
  7. Early 1970's Talis electronic (ESA9158 cal.) for me today........
  8. Thank you, all four watches are 4100 series and date to 1975/6, they bear little resemblance to the normal 'chunky' quartz analogue watches of the mid 1970's and initially I had thought that they were mid 1980's but research showed that the movement was indeed 1970's only and examples of them can be found in the Seiko 1976 JDM catalogue, where they were selling for about 50,000Yen (The 6105 divers watch, in the same catalogue, was only 20,000Yen) . You don't see them very often, other than in Japan, as I think that they were mainly for the Japanese domestic market....
  9. Where do I start? In no particular order, here are a 'few'........ There are more........
  10. Correct crystal for 7009-8140 is ... Seiko 320W19GN00 Available from Cousins...
  11. You've prompted me into donning my vintage Timex digital As an aside, with these vintage digital watches, if you want the day and date to be correct for 2020, set the calendar on them for 1982.....
  12. Well this evenings announcement from the PM says that ALL shops, other than food stores and chemists will close.......
  13. I remember having an LED watch back in the early 1970's Andy, they really used to eat batteries then, battery life, under normal use, measured in a very few weeks rather than months. I seem to remember that the screen was usually blank and only illuminated , for a few seconds, when you pressed a button to read the time. The nearest, that I can find a picture of, to the one I used to have, is this Omega one:-(and no, my one wasn't an Omega!)
  14. I must have done about a dozen balance assembly removal/replacements on these movements, and while aware of the magnet influence on the balance, when replacing it, I have not yet had to resort to removing the magnet to get it back together and in place.....perhaps I've been lucky? I am surprised just how resilient the balance spring is, on these movements, and how much 'mishandling' they will take with out permanent distortion....
