  1. Can you take some good hi res pictures of them too. Particularly the snoopy ones. It may be possible to make copies.
  2. Don't tell anybody I showed you this. Its probably classified.
  3. True, from the dial side, but what was the dose through the case? What was the dose through the crystal? Mostly Radium throws out Alpha and Beta radiation, so most of that isn't going anywhere. https://en.wikipedia.org/wiki/Isotopes_of_radium#Radium-226 Some of the gamma will get out. Dust is the real hazard. Take care when dealing with that.
  4. 1 million years = 31556952000000 seconds (3.155 x 10^13 seconds) https://en.wikipedia.org/wiki/List_of_radioactive_nuclides_by_half-life Radium 226 has a half life of 50x10^9 seconds or around 1,600 years .. so 1 million years will probably make the lume on those hands safe enough to spread on your toast. Having said that, the radioactivity is relatively low level, so providing you don't actually intend spreading the lume on your toast, and it will remain in the watch, and that the watch is not worn daily, for may years, then its probably not worth worrying about. Most of t
  5. Just for fun I picked up a gieger counter kit from ebay a couple of months back. https://www.ebay.co.uk/itm/Geiger-kit-DIY-Arduino-IDE-compatible-easy-nuclear-radiation-counter-w-o-tube/153986465695?ssPageName=STRK%3AMEBIDX%3AIT&var=454085217095&_trksid=p2057872.m2749.l2649 Its been sitting waiting for a spare moment to put it together, so this evening I grabbed it and assembled the thing, which took me less than an hour. I do however have quite a lot of experience of electronic repairs and soldering, so I found it pretty simple. Your mileage may vary. I'll complet
  6. Initially I had it on a fairly boring tan leather strap, which sort of worked with the red, but then I grabbed this midnight blue one with red stitching. It actually echoes my ThinkPad laptop's styling pretty closely too. I'll leave you to decide if Timex were ahead of their time, or Lenovo are harking back to a different era.
  7. Timex Tuesday again for me. This time a 1973 Marlin with a great 70s vibe.
  8. Another novelty watch for the 404 club. A Fero with a rather odd exhibition case back, and palm tree motif dial. Listed as not working, and with the regulator suspiciously pushed to one side, I suspect this may need a bit of attention. I may also need to resort to some serious metal bashing skills to sort out that 1960s stainless band too, although that is almost certainly not original.
  9. A quick search online turned up a possible substitute, namely calcium sulphonate, which is used in marine greases for the same purpose as barium sulphonate. I suspect the chemical action will be almost identical. At $15.00 or so for 400g, this stuff is cheap as chips when compared with Swiss watch oils of course. But then again, so is Chanel No. 5. In fact named brand Swiss watch oils make named brand printer inks look like generously priced products. The thing is.. do I feel brave/stupid enough to squirt some of this into the mix. The interesting thing is, it doesn
  10. One of the missing ingredients as gleaned from the various - Extra Virgin - Swiss gold bar pressings oil - hazmat data sheets found online, that might be worth investigation is barium sulphonate. This is used as a rust inhibitor. I suspect it is probably not strictly necessary, since not all of the hazmat sheets mention it. If it can be found relatively easily, then a few drops (1% or so by volume) might provide a small measure of additional protective not so secret sauce for my "Horse Lineament" branded not so Swiss substitute. It also seems to be a common additive in motor oils, so i
  11. Buler appears to have had a large number of watch trademark names. Somewhere of the order of thirty. http://mikrolisk.de/show.php?site=280&suchwort=Buler&searchWhere=all#sucheMarker More about them here -> https://www.buler.ch/en/brand/history.html
  12. Thanks in no small part to you. It looks pretty good considering it was just lying around as scrap. I still need to regulate it, but its not miles out, maybe 80 sec/day and slightly out of beat, but it is running pretty nicely. I may have the making of another BFG 866 17 jewel date mechaism, as I appear to have one more good balance staff with wrecked hairspring, and one wrecked balance with good hairspring. I'm not sure if I can graft the good bits together without wrecking them. I'll have a go some day.
  13. @Bradders recently posted, looking for information about the venerable Baumgartner BFG866, and as a result I had a trawl through my spares to see if I had the makings of a complete movement. I wasn't quite there, however today while tidying up and organising things I came across this Buler 17 jewel 866(CLD) sweep second, date version. It had a smashed crystal and the balance was loose, but surprisingly when I inspected it, far from being damaged, the only issue with the balance was a loose balance cock screw, and a slight kink in the hairspring, no doubt due to be balance rattling about l
  14. Nice. If the source has the hands too, especially for those Snoopys then you have won a watch.
  15. Believe me if there were still bits of old Timex lying in the bins there I'd have grabbed them. https://www.google.co.uk/maps/@56.4847228,-3.0190493,3a,75y,279.18h,92.19t/data=!3m6!1e1!3m4!1sfYBm3nTCOUG_q2y0xATfXg!2e0!7i16384!8i8192
  16. Very interesting documentary. I missed it when it was on TV. I thought the movements had to be built on a jig, and there it is.
  17. Continuing with the Timex them, this time its a Timex 392 ana-digi from the late eighties or early nineties.
  18. An extra Big 'Q' bonus. The previous watch, joined by its champagne dialled date cousin from the same era.
  19. Nice. I'm not sure why image linking seems to be broken at the moment, but I pasted the image here 'cos its too good to miss.
  20. Nice. Maybe we need Big 'Q' thread.
  21. Thanks. It took a few attempts to get the catchlights the way I wanted them in that picture. I didn't want to break out any special lighting, so they are both done with the camera hand held and with just the table lamp next to the sofa and the main light in the living room. They are perhaps not as sharp as they might be, but I think the softness works with the warm tones. I also managed to ruin about a dozen shots with random whiskers from my hairy arms and some distracting reflections. You wouldn't think taking a decent shot of a wristwatch could be so tricky. Maybe I should s
  22. Its Big 'Q' Timex Thursday today. This 404 club watch is most probably late seventies or perhaps early eighties. Either way it is not far shy of forty years old and still going strong. It wasn't a particularly cheap watch in its day, retailing for around £34.95 GBP which equates to about £157.00 today.
