American PW '92 escape for 17 jewel ATCo.

[Daniel W.]

Guys I need an escape for '92 Waltham AT&Co. 17 jewel. Mine is an early first run. Will any 17 jewel work or did they change pivot sizes later on?

Daniel, Model 92's are terrible for matching parts. Throughout the life of the model, Waltham played with and changed specs, including arbor and pivot sizes. Try to get an escape wheel from a scrap movement near to the SN of your watch. Still, there is no guarantee that it will fit and work.

Good luck.
