When you succeed in reading the time, you then must subtract 1 hour again, to know what time it was when you first decided to find out.

The latest in CuriousMarc's series about repairing a 1960s Atomic Clock.
This time its an OCX - or to be more precise a double oven controlled crystal oscillator, from the early 1960s.

These were used to keep your precision time source in step with an accuracy of parts to 10^-11
Somewhat more precise than the average crystal oscillator that probably adorns your wrist.

If you haven't seen the rest of the series, and interesting time pieces are just the thing to brighten up your day, the rest of the series of videos are well worth watching.

You might all enjoy reading about the Le Coultre et Cie "Compass" camera...

Yes you read that correctly, they made cameras, but not just any camera, this is a marvel of Swiss engineering and British Design.

If you want to know the details... and why wouldn't you? follow this link -> http://camera-wiki.org/wiki/Compass

They turn up on ebay from time to time, but they are a little pricey.

Brilliance or madness!!

Its a fine line between the two, but in terms of honing your machining skills, definitely brilliance.

    • Righty ho, I re-serviced the chrono module and got a reasonable result with minimal loss of amplitude when not running the chrono and about 30 degrees loss when running. Great. The problem is now that the chrono (and movement) stops running after about a minute or so, a tap on the watch starts it running again. No issues with the movement running when the chrono is stopped. Going to service it yet again, obviously some residual issues with friction in the chrono module (Very frustrating - I wish there was some way of testing it as I go!) I also seem to have a problem with the cannon pinion where the movement is running continuously (with the chrono stopped) but it's losing significant time / stopping. This is one of those two piece ETA style with a driving wheel pressed over the cannon pinion, obviously arranged for driving the chrono module. I had no issues with this prior to service and just added a small amount of grease between the driving wheel and the centre cannon pinion as the technical guide required. What's the best way of tightening these up? I would like to replace it but I guess this is going to be hard to find as it is dedicated to the DD chrono movement. 
    • He uses the micrometer cap, but he leaves the spring out (you can see that in the video). If you leave the spring in, the spindle will move up as well (as shown by @Knebo).
    • Seems like he doesn't have the micrometer cap  attached to the spindle so he can only push down but cannot pull up? If the cap screws into the spindle I guess you don't need the spring? I only have a "normal" Seitz so I really have no idea. 
    • Do you have a part number for the bearing shim lock tool?
    • Yes in my opinion the 3/4HP is plenty but it’s your decision & yes it does come with speed control but foot operation so my reason for changing to potentiometer was because my leg shakes so it was like me revving the lathe & anyway I prefer to set the speed. I & a few others that I recommended the motor to run a Pultra 10mm lathe so if you have a 6 or 8mm B & L then it will be plenty, if you have seen any of my videos you will have seen that when using a graver I run quite slow without any problems.
