  1. Well it certainly isn't shy about letting you know it is ticking. Its actually not too bad (for a 1967 Timex mechanical). Not exactly COSC, but not bad, given that it is a slightly agricultural bit of 1960s technology, which almost certainly has only been serviced once in its lifetime since it left the Dundee factory all those years ago. Its seems to have survived my servicing reasonably well too, since it is still going strong more than two years later.
  2. 1967 Timex "Self Wind" Viscount.
  3. Hmmm... I'm not sure about that, you may be correct, but generally these microscopes are pretty rudimentary and consist of a lens at the eyepiece, and a lens or bunch of lenses in the objective. The critical part is the length of the tube between the lenses. Too long or too short and it will never focus. Could it be the case that something has altered that length. Maybe some previous owner has jammed something or re-assembled it incorrectly. Modern microscopes tend to have "standard" tube lengths, but older ones may be pretty much whatever length the manufacturer dreamed up, so over
  4. Perhaps. There is also the possibility that some previous owner has re-assembled the lens elements in the wrong order, or with the wrong spacing. How many lenses are there, and what do they look like?
  5. Nice, how are the optics faring up after all these years? Generally if they have managed to avoid any acidic fungus attack, microscopes can be cleaned up to work like new, since there are few moving parts, and little therefore to break. There is a bit of an art to cleaning optical glass, but if you can fix watches, then you can master mirror, lens and prism cleaning pretty easily. If there is any mineralisation in the local water, then used distilled water for washing optical glass, with a little dish soap. You can also use denatured alcohol and if you are careful, acetone (which mak
  6. Testing dive watches the Finnish way. If anybody makes fun of your Bostok. just point them in the direction of this video. Oh... and the oil filled cheap Pulsar is pretty impressive too.
  7. Reminds me of a recent visit from our local plumber. I had attempted to unblock the bath drain with caustic soda, which was a complete failure. As a result I now had a solid lump of caustic soda, old hair and calcium in the U-bend. The plumber, who I know quite well arrived with a plumbers grade fix for the problem in the form of sulphuric acid. We poured in a tiny amount and there was an interesting explosion. Rather than do the obvious and desist from continuing this potentially disastrous line of repair, we agreed the best course of action would be to remove the entire blocked U bend
  8. Interesting, I wonder how many of these made it in to the wild. They would need to be very early Scottish Timexes, probably branded UK Time Corp or similar.
  9. Very nice. If you took a note of the movement number and any serial numbers it should be fairly easy to figure out the year it was manufactured. My guess is 1930s There is a tool to do that on this site -> https://mybulova.com/
  10. Completely unrelated to anything to do with watches or clocks, but as you might observed, there have been a few hints about flying "toys" in this thread. I picked up a bunch of Eachine E58 drones. I blame covid related lockdown boredom. I wouldn't claim to be actually "dangerously" bored, but I've been sailing pretty close to that level of boredom. These are not what you might call "real" drones, but none the less they are quite impressive little gadgets. A quadcopter with built in multi-axis gyroscope, barometer, wifi camera and 2.4GHz remote control that has a claimed range
  11. OK I admit it isn't the next morning, but I hope this answers the question. The lens tube unscrews into various bits and the base can be removed from the turret using a set/grub screw. At least this is the case with the version I have. From what I have seen online, there are quite a few variations with similar designs though.
  12. A Ladies Glashütte 17 jewel all the way from sunny Boden Edelstahl. That's as close to a German joke as I can muster. Boden: Edenstahl translates as Bottom: stainless steel, but Boden Edelstahl does sound very like an idyllic spot in the Black Forest. Glashütte is in fact a town in Lower Saxony from which the watch manufacturer takes its name. It is 14k plated, shock-proofed (stoßgesichert) and probably from the 1970s to judge by the design. It is a non runner, and not quite in the same price bracket as its modern counterparts which start some where north of £5,000. In
  13. I'll check in the morning, but as far as I recall the tube unscrews to allow you to access the lens. Let me take a look and confirm that.
  14. By the way, "The basic specification of the Standard wristwatch caliber is a minimum of 17 jewels, 21,600 bph (beats per hour) escapement, a minimum 40-hour power reserve and an average rate within +/-30 seconds per day." The ones I have perform better than this, but an average rate within +/-30 seconds per day is the figure to shoot for.
  15. If you are careful, and take your time, there is a pretty good chance you will get it working.
