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.

      Epilame / Fixodrop

      By Waggy · Posted

      Maybe I'm over simplifying this and I'm a little late to the discussion, but just by my looking at oil when I use it on a treated cap jewel  the oil stays in one nice bubble, but when I don't it spreads out to the edges of the jewel. I'm not sure (but could well be wrong) but the analogy of a waxed car and rain is accurate in this case, the wax is very hydrophobic and repels the water, however, the process epilame works by is a different physical process based upon cohesion/adhesion (oleophilic) not repulsion (oleophobic)  at least as far as I have read/observed. If one were to use a oleophobic substance equivalent to wax (hydrophobic) then one would need to create a donut shape to fence in the oil, however if one used such a strategy with a epilame which is oleophilic then the oil would sit on the ring of the donut and not in the 'donut hole', exactly where you don't want it. Even if the oil is smeared then the oleophilic epilame should pull it back to the center (see diagram below). Reference For interest the chemical in epilame is 2-(PERFLUOROHEXYL) ETHYL METHACRYLATE, CAS NO: 2144-53-8

      Looks lint the teeth on the hour wheel aren't meshing with the teeth on the calendar intermediate wheel, maybe the hour wheel is sitting on top of this instead of meshing?

      If the oil drop was freely standing on an epilame treated cap jewel it could easily slide off if you knocked the watch hard but the balance pivot keeps it in place.

      Latest 404 is this Baron which has a copy of a Seiko 66B movement in it, handy when I needed to find a replacement setting lever. Apart from the setting lever, crown, stem and new crystal (original was cracked) the watch is original. Finished result:
