    Watch of Today

    Nice Omega JBerry , ... I too have seen the Turler logo on a few fine vintage watches . Kinda like Tiffany I imagine . While I will quickly admit that I am addicted to Hamilton watches new and old , I recently had the opportunity to service a vintage Gruen with a 480SS movement and was impressed with the interesting design it presented . Multiple winding barrels , levers , clicks , and srpings . Also very nice finishes to the movement parts . So I have been on a Gruen phase these days . They are nice ..... Here's one I recently acquired as a good deal because it was sold as a non-runner . The first pic is the sellers .

    Radon Hazards of Luminous Timepieces

    In this months BHI mag (November 2018) is an article “Radon Hazards of Luminous Timepieces” Understanding Risks From vintage watches. Luminous timepieces really took off during the Great War, when a wristwatch with a luminous dial quickly became regarded as a necessity. The hazards of radium paint were highlighted by the story of the “Radium Girls”, luminous dial painters of the 1920s not only shaped their brushes with their lips ,but painted their teeth, lips and eyebrows with luminous radium paint, consuming significant amounts of radium. When Radium enters the body it results in cancers and many died from this. The problem for us watch repairers is detecting if the vintage watch you are repairing/servicing has a radium dial or hands is not easy. Radio-luminescent paint ceases to glow after a few years, so lack of glow from the paint is not a reliable indication of whether it is radioactive or not. The only way to be 100% sure is to use a radiation detector. Conclusion Radiation and radon gas from radio - luminescent paint a potentially dangerous to watch collectors and repairers. Open storage in living or working areas that contain potential Radio-luminescent paint should be avoided. For those who regularly work on vintage watches should invest in a radon detector. If not sure use a mask when disassembling and store the dials and hands under cover and wear finger cots when handling.

    My new apron, a simple solution.

    The lowly kitchen apron to the rescue. After having spent way to much time on the floor looking for parts and finally bending the pivot on a newly installed balance staff it was time for a solution. Pip to the rescue with his recommended Jacot video by Richard Edwards. While the video was certainly informative on the use of the Jacot tool, it was his use of the apron that caught my eye. Pure genius I thought and raced off to the nearest craft store for a plain white apron with no pockets. After I endured the smiles and jokes from the wife it was time to try it out. Brilliant is all i can say. It simply clips to the underside of the desk with spring clamps and slips over the neck no problem. Easy as pie. I dropped parts all night and not one hit the floor. It is easy to remove and I just leave it clipped to the desk if I have to leave for a bit. Probably old news to most of you but hopefully it will keep someone else off the floor and at the bench. picture not uploading for some reason... Ron

    Picked up this Omega Constellation this weekend at a price I couldn't say no to. Has a 564 movement in good shape. Anyone seen a dial like this before on a constellation? Case is a 168018

    Radon Hazards of Luminous Timepieces

    There Geiger counters out there on Ebay. Very simple ones just put it in your smartphone's 3.5 jack and install the related app and use it. 20-30 USD for the sensor. Youtube videos shoving remarkable accuracy compared to a real detector piece. I am planning to buy one.

    "Zentralverband der Deutschen Uhrmacher" I can see how that inspire to name a brand ZenTra. Here is my watch from the German watchmakers. It comes with an center sweep instead of a sub second, to accomplish this the powerhouse has been modified on the drive bridge and is therefore called Guba 1050SC.

    I attach mine to the underside of my desk with Velcro. This way if I forget it's there and move away/stand up I don't end up pulling the desk (or my neck!), it just detaches. Stephen

    Radon Hazards of Luminous Timepieces

    The actual dose you receive from working with lume is probably relatively insignificant, even if it comes in contact with your skin. Ingesting or inhaling lume on the other hand presents a somewhat greater risk, particularly if you do so regularly. If you were to remove and store all of the lume from every watch you ever encountered, and then swig the resulting concoction, the acetone would be a more immediate hazard. Here is a chart of relative doses that brings some perspective to things. https://xkcd.com/radiation/ It is factually correct to state there is no such thing as a safe dose of ionising radiation, but since you are being bombarded with the stuff naturally, the additional risk of working (sensibly) with lume is relatively low. Flying from LA to New York is more risky I would suggest, and even then, the risk is pretty low.
