Replacement of impulse/roller jewel

[JohnTosto]

Hello All

I purchased a non working Waltham  model 1877 grade PS Bartlett ser# 1998658.  When  opened it I was excited to see the balance was swinging freely however quickly realized it was not ticking.

I am sure you guessed roller jewel was missing.  I have  watched a few videos and read a few articles and seems very difficult and requires a lot of patience but  its not impossible and want to give it a go.

I have all the tools needed the only thing I don't have is the roller jewel, one video I watch he went  through a large assortment of jewel until he found the one that fit is that the best way.

I found some on ebay which are from Red Roster UK which sales watch tools and parts but lists them as "100x Roller impulse watch jewels new old stock repair pin ruby watchmakers part" and another as "Watch Roller impulse jewels repair pin ruby watchmakers parts Vintage x 100 Mix"

My concern is they say watch and not pocket watch should I be? Also  love any advice and/or tips.

Regards 

John
