Hi Busakaz

I am not really sure if this is even what I need. I have a Waltham Model 1877 18s Appleton Tracy with broken Escape Wheel pivot. I am looking for the part number and perhaps cross reference numbers, or other models this part may be available in. I think I found a catalog which gives me part number.  Looks to me like 948 is wheel alone. Numbers 949 and 950 are slow train and quick train parts Not sure which one I need. What Should I look for? Below is a picture of what I need to replace. I will save this part for a later date when I take a shot at pivot replacement.

Is this basically what The other Manual of American Watch Movements has to offer as far as Waltham's go?

Here is a copy of Catalog I found in case another beginner can use it.

MY Bad

Looks like this is open face configuration so it would be 951 and 952

My book doesn't list that movement number it only lists 1883,1892 in size 18 and all part numbers have 4 numbers not 3, let me know if I can help

regards kaz

Ok I purchased a donor watch with the escape wheel I needed. Both watches are model 1877 but different classes. The escape wheel pivot from the donor fits in the bottom plate jewel but the pivot is to big for the top plate is it customary to trim the pivot to fit  or replace jewel?

There always seems to be an issue with watch repair. It just shows you how much you really don't know every step of the way.

      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.

      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...
