  1. I'll play. I picked this one up a few months ago for just over £20 as I just fancied a manual wind Citizen. After a full service and a spruce up it has become a regular wearer. I just love the lollipop seconds hand.

  2. Roland Ranfft is offering two re-luming pastes with excellent instructions on their use (as in Mark's video). One is based on the phosphor Zinc Sulphide (ZnS) , the other on Luminova. http://www.ranfft.de/cgi-bin/bidfun.cgi?10&ranfft&b7&1usem&1456959600 http://www.ranfft.de/cgi-bin/bidfun.cgi?10&ranfft&b7&1usem&1456959601 These will glow for a few hours after exposure to sunlight (phosphorescence). The early Radium luminous dials and hands glowed continuously due to the very long lifetime Alpha and Beta emission. Today an early Radium dial has no more radio-luminescence due to radiation damage to the phosphor (usually silver activated ZnS). But a dial with a good coating of old luminous paint (see below) can be brought to life again by applying a new overlay of ZnS. I asked Ranfft to test this out and he found that non-activated ZnS applied over an old radio-luminous dial did glow even after several hours in the dark when the light-activated phosphorescence would have vanished. He also reported that Luminova was also activated in the same way but with more brightness than the ZnS. Our conclusion is that if you have a radio-luminescent dial in good condition such as this one Then it could be brought to life again to glow all night long by the application of a layer of Luminova paste over the old numbers and hands. Silver activated ZnS paste would also perform well and be nearer to the original. Activated ZnS is available in small quantities from: https://unitednuclear.com/index.php?main_page=product_info&cPath=16_17_69&products_id=218 If you do want to get into this game then buy a cheap (post Fukushima) radiation monitor from one of the Japanese eBay sources. The above dial has a radiation dose rate above the crystal of 40 micro Sv/h. This is ample for a re-luming job.

  3. Possibly they came off due to the dial being loose, and as a result, it lifted away from the movement, pulling the hands off their pinions.

  4. wow... looks magnetized but I would have thought it would be more like 6 minutes an hour! Try to demagnetise ... you may need to do it a few times... read the instructions (for the demagnetiser) Anil

  5. If you check out this thread I posted a link to the Chinese supplier. http://www.watchrepairtalk.com/topic/1645-automic-test-cyclotest-watch-tester-watch-test-machine/?hl=%2Bwatch+%2Bwinder#entry17150 Micky, I do like the stand you have the winders mounted on. :) CB, your video won't work on my IPad for some reason. :(

  6. Yes it is great, I love it! It looks to be in "mint condition" (pun intentional!) I found a Mcdonalds watch not long ago, not a happy meal one and a Burger King watch. I've also found a nice Fedex watch, a Best Buy Watch and many others. They are fun novelty items I think, I know that many of them have very little commercial value but fun to own or wear on occasion, I must confess that I wore a Mcdonalds happy meal Hello Kitty watch for a day a few months ago. Commercial advertisement watches would maybe make an interesting new thread.

  7. One of the interesting aspects of watch repair is the discovering of variations. Not just case variations dial variations the hands but movement components. The watch companies seem to have an endless supply of ideas of how to do things giving us an incredible quantity of things to torture us with. Although I'm not sure they were actually specifically designed to torture the watchmaker they can end up doing that. So the links below have additional information lots of pictures lots of variations of using this regulation system. The third link if you scroll down far enough has a picture of the inside of the case back which has the setting instructions. http://forum.chronomania.net/mix_entry.php?id=120965#.Vh6V9viyJyx http://www.ceasornicar.ro/forum/viewtopic.php?f=13&t=6234 http://goldsmithwatchworks.com/MAY-2012/ERNEST-BOREL/1954-ERNEST-BOREL-14K-GOLD-CAPPED-STAINLESS-STEEL-CASED-LUXURY-WATCH.htm Then I've attached a image for an advertisement for another system called a triostat

  8. Todays choice is a 1968 Timex, this surprisingly is very accurate.

  9. That was something I hadn't thought about when I bought it. I decided to put it to the test and see what was going on. Luckily I have one if these see through automatic watches, so I put it on the machine to check things out. What I found was, due to the myriad of contorsion the watch goes through, the rotor fell in both directions. It did have a slight bias for the weight to turn in a clockwise direction as viewed through the "front" of the watch. This was when the machine was rotating in a clockwise direction. Another thing at I discovered, the machine does not always run clockwise when switched on, sometimes it goes anti-clockwise. When thIs happens the watch was observed to have the same bias when winding as it did when the machine was running anti-clockwise.As promised here's photo if the drive gears and circlip. It definitely isn't the best quality, but I checked all the clips for proper location and tightness, and all seemed OK. So far "for the money" I'm very happy with it. It's run for about forty eight hours so far without any problem, but if it does start falling appart I'll let you know.
