With the indispensable help from my buddy J Trenalone on the West coast, this ~80 year old monopusher chronograph is back in working order.  There were a multitude of issues getting this working. The balance staff, escape wheel and mainspring all gave their share of headaches. Slide1.jpg.53d810b4c644d5b150e026a2240c1335.jpgSlide2.jpg.4818e166cb0d3e405da57239eea54951.jpg

I also have to mention that I bought TWO new mainsprings from Cousins that broke one after another when tested. The mainsprings are listed as GR5032 and are supposed to be correct for the Landeron cal 2, the cost 11.80 each and after shipping  £22.64. I think they were no good to begin with because of age.  I finally had to buy one from Borel using the measurements form the original, which had set and needed to be changed. Finally it has come together. I you try to find these, you'll quickly discover they are difficult to come by. Its someone else's watch, and I appreciate the opportunity to work on this type of early column wheel chronograph20190204_102613.thumb.jpg.3abbc1ffa121c05252964c1d81193fdc.jpgSlide2.jpg.cfe5c16d17866ce541e08523dc3b3bc8.jpg

      What are these Seitz B-Jewels?

      By nickelsilver · Posted

      It's pronounced "bombay" like the city.  French for bomb is, 😄, bombe, pronounced the same as in English. Bombé, bombe.

      That's a really good idea! I have a 3d printer, I think I'll design something that I can clip on to the edge of my desk to do the same. Thanks for the idea.

      I looked up bombè, domed in French.  It's pronunciation is bomb, does a bomb (explosive device) get It's name from bombè? I know we're going off subject but it's interesting.

      1972 Bulova President "E" Sea King 11ACACB movement

      Okay, I checked with the fine folks at the McCaw Company, and they agree it's the correct crystal, and they have one in stock, so with that sorted time to get onto assembly. Starting by getting the spring into the barrel, which was a bit harrowing. It took me several tries to get it hooked onto my worn old winder arbor, but I did find a new use for the micrometer stand I just purchased. Carefully dabbed some Kluber P125 braking grease to the left of the divots around the barrel, and a little HP1300 on the floor of the barrel before popping it in--in case you haven't seen it, this is a great illustration I found somewhere on this site. You're not the boss of me, Bulova.   2172_Bulova 11AOAC 11AOACD 11AOACB.pdf Bulova_11 AOAC, D, B(1).pdf I got the train back in and it didn't seem as free as I'd like. Looks like the driving wheel with cannon pinion has zero end shake. That could explain the low amplitutde I started with. Now if you were me, would you push on the plate jewel or the bridge jewel? I've attached some extra pictures in case anyone sees something else I'm doing wrong here.

      What is it about this watch that speaks to me?

      By Razz · Posted

      I have quite a few watch brands from all over the world. For some reason this Timex electric from 1979 is capturing my attention this week. I am not a particularly fond of battery operated watches or Timex, but this one is different for some reason. Post your watch in your collection that seems to draw you in more now than before...
