  1. Balance staff came out :(

    It’s called swaging. Careful in doing it and support it well as you could distort the balance arm out of plane and add another problem.
  2. My Basic Watch Repair Tools

    Reminds me of the adage " He who has the most toys wins ". My wife usually says when another package ( my watch tools ) comes in, " Everyday is Christmas ." Anyway, happy for you. Keep it coming! Sent from my iPhone using Tapatalk
  3. Frozen case

    Hi Steve, Your right, the rubber gasket get very gooey ( described as tar ) when it ages. This apparently a common problem in Omega F300 among other things . I managed to open the case with help ( suggested technique ) from others who have gone down this horrible path. Thanks for posting. Sent from my iPhone using Tapatalk

  5. Frozen case

    Oh yeah! Finally it opened. Thanks Ray. Thanks Frenchie. It worked after 2 tries. First try, I heated the watch in the oven, then transferred to the vise block , mount the case opener carefully, apply pressure with the aid of a mill press, then apply some torque to open, then hit it with the coolant. Didn't work. The problem, getting it setup took time. Maybe I cooked it too much to. The second time, it set it up ready to open position ( vice block, case opener aligned pressing on the case. Then I heated the whole setup with a heat gun, then hit the back with the coolant and it finally gave. I still had to open it half way using the setup since after cracking the case I still could not open it by hand. Again, thanks for the response . Pics enclosed. Sent from my iPhone using Tapatalk

  7. Frozen case

    Ray, that's why I was thinking of an oven where I can preheat to 115 and leave the watch there for about 30 min. That should warm it to the core. Then install the case in a vise with wood blocks, apply the case opener with some torque, then spray the back with a spray coolant like ethyl chloride. Sent from my iPhone using Tapatalk

    Thanks for the input. I was thinking of an oven with careful temp monitoring then set up the vice wooden block with the case opener . Then spray ethyl chloride on the case back for cooling. Will Also do the oil around the case/backing junction and let it penetrate maybe overnight before doing it. Thanks for the input. I'll post the results. Sent from my iPhone using Tapatalk

  11. Frozen case

    Good day. I have an old Omega Electronic F300 that hasn't been serviced in a long while. It's not working. Attempts to open the case has confounded me. I have a professional case opener that resulted in gouging the back. The studs that go in the notches of the case back were firmly held in place but the case back would not yield. I finally resorted to epoxying a nut on the case back. The junction between the case and the back was pretreated with penetrating oil carefully. The case was held in a vice with wooden blocks with powdered rosin. The result is the picture. I am open to suggestions/ideas on how to open this case. Sent from my iPhone using Tapatalk

    Here is a pic of mineral crystal (sideways showing ridge) and gasket ( with human hair next to it for size reference ) showing ridge for crystal. Ed
  13. Domed and flat mineral crystal fitting

    Be careful. Flat mineral crystals sometimes have gasket that go on the outside around the perimeter of the crystal as the crystal has a ridge and the gasket has a depression specifically for the ridge of the crystal. In other words, it can only go on one way. I'll send a close up picture of flat mineral crystal and its gasket. Currently out of town. Will upload tomorrow. What watch are you working on ? Close up pics are helpful. Ed

    It's a beauty. I like the skirt how it blends the case to the strap. Very hard to come by. Congrats !!! Ed
