  Install/replace part 228/8270 Venus 170
  
  I had occasion to reset the set lever. When doing so, I found a piece of the above part lodged under the rocking bar?. I don't know if I broke this part or if it had been broken previosly and ended up where it ended up. I have the part, but without an exploded view I have no idea of the location or if it something I want to try to replace. Any thoughts appreciated. Regards Jack

  Mainspring winder and braking grease advice from Aliexpress for Omega 550 series barrels?
  
  I am still not sure if „breaking“ ist the purpose of a breaking grease. It should just prolong the life of the highly loaded inner wall of the barrel which serves as a kind of breaking drum imho. That’s why MoS2 is used. Unfortunately I haven‘t found tests which compare power reserves of differently lubed barrels. Any ideas here?

  Mainspring winder and braking grease advice from Aliexpress for Omega 550 series barrels?
  
  From Esslinger website: This special purpose Moebius grease contains Molybdenum disulphide to enhance it lubricity and resistance to pressure. It is designed for use on automatic mainsprings, to ensure proper functioning of the bridle. It is also recommended for use on the Bulova Accutron watch movements. Moebius 8201 natural watch grease lubricant Contains Molybdenum disulphide -------- I use this.

  Illinois Watch Co. pocket watch stuck screw off bezel
  
  I was afraid this would be the answer. I will try a drop of oil, and also may try a method I saw where you hot glue an appropriately sized jar lid to the bezel and use that to turn it. I feel like it would be better than the ball in this case since I won't have to apply downward pressure on the threads to generate friction, like with the ball. A drop of P'Blaster and the hot glue got it done. Really interesting that you need to take the bezel off to set the watch and pull out this little lever. To add a little historical info: I own a brewery, and one of my customers brought this in for me to look at. It was his grandfather's, and no one knows the last time it was used. I wound it up and it sprung right to life. Not only that, but it looks better than a lot of more modern watches I've had on the timegrapher. Not bad for 140 years old! Here's a little video of it merrily tick-tocking away.

  It is just basic there is no real math to it. You do not measure the barrel and work calculations out. I learned it just by word of mouth by my master.

  Janta / Pearl Watch Cleaning Machine
  
  Those cycle timers are available in the same configuration by many different manufactures. They are fairly common for use in machine automation and prototyping. To your second question, are you talking about the plumbers test cap for 3" Pipe? the Janta jar lids do not seal completely, the gaskets are horrible so to prevent evaporation and odors I fitted a plumbers test cap to seal the jars and not use the Janta lids. Just insert the test cap and tighten the wing nut until sealed. Price is about $8.00 US for 1 test cap. Please post your results when you get your Janta modded, best regards Trey, James.

  True. But you can use the numbers above: Thickness of released spring packet = 1/4 barrel radius And I want to apologize. Not you were wrong but Mr. de Carle was. Frank

  Jaeger memovox 8 days desk clock, need help with balance staff!
  
  I got the clock back from the watchmaker yesterday, from what I understand he (the watchmaker) rebuilt the staff end and pushed the jewel down by adding a second jewel. It is now working properly. He charged me around US$25, hard to believe eh?

  Zenith El Primero A385 year 1970
  
  You don't have many options. Zenith does sell parts to watchmakers who have an account with them, but they made it essentially impossible to get the account several years ago (a friend had and then lost his account then). Your options are: send it to Zenith, who will do a full service including repairing/ replacing the hand, or, take it to a watchmaker who does have a parts account, or, be patient and hunt Ebay until a new old stock hand comes up for sale. A 1970 El Primero will be in dire need of a service (unless done in the last few years), and may need other parts as well.

  That makes perfectly sense! Nevertheless calculating areas is a bit difficult for a rule of thumb. So the 1/3 rule is not useless as a first approximation imho.
