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?

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.
