Master Navigation Watch (4992B) Manual

It appears to me that pages 10, 17, 21, and 23 are missing from the 1956 manual posted in the Hamilton Horology section. Am I doing something wrong?

I'm looking for any and all service information available for the 4992B so I would be very grateful to anyone who can provide the missing pages or let me know where they can be found.

Thanks in advance for your help.

I found the complete document on a French watch forum Chronomania.

Hi, I am new to ihc 185 and this is my first attempt at a question. I have a Hamilton 4992b with a bad balance staff and hairspring. Would parts from a 992 fit the 4992b? How do I find the service manual/ Thanks, Bruce

Hello Bruce & welcome to the site.

If I remember correctly the 4992B uses the same staff & hairspring from the 992B not the 992.

I may have a PDF copy of the military manual AN5740
for the 4992B. I will search my hard drives & see if I can find it.

HI Bruce, Follow this link an you can down load the parts catalog.

4992b

I found the file but since Phil provided the link that works just as well.

Hi and thanks for the response. I found the parts list but no mention of a manual. I order a service manual off of ebay for the 992. Also I found I guess you would call it a blog by HandtDan on WWII 4992b pocket watch overhaul. It was very well done. Thanks, Again Bruce
