JerseyMo Posted July 10, 2023 Share Posted July 10, 2023 (edited) Here is what I worked on this weekend. Wittnauer ESA 9150 Timex - Marlin "Red Dot" Diver, Mercury, Viscount, Electric, SSQ. Two still need crystal replacement and those should be in this week. Most fun was the ESA9150. Needed a new electric coil and a donor balance assembly. What did you work on?

Razz Posted July 10, 2023 Share Posted July 10, 2023 (edited) I worked on this 1975 Caravelle. I picked this up as a non runner a couple of months ago and could not get it open. I doubt the last owner could either. The back was chewed up a bit and I admit that I probably added 1 or 2 markes to the caseback trying as well. Even though it is not a screw caseback I had to revert to the super glue nut to finally get this open. It has a Bulova 11DP movement which is a Citizen 0241. It is only 7 jewels. So last night I glued the nut on and this morning got it open. Striped it down and then reassembled, oiling as well. Not a lot of amplitude but I did get it running. Once my 8200 gets here this week I will go back in and clean and oil the mainspring to see if I can get more amplitude. I really like the wet dial look on this one. I had an extra crystal of the correct size to install, and cleaned up the case from the requisite DNA. I am reluctant to close the back as I had so much trouble getting it open in the first place. The balance shock system on this one was not that bad to navigate to oil the endstones and reinstall. Edited July 10, 2023 by Razz 2 Quote Link to comment Share on other sites More sharing options...
