I have a formaly RESRICTED tech. manual on this pocketwatch.
Title; OPERATION,SERVICE, AND OVERHAUL INSTRUCTIONS WITH PARTS CATALOG FOR MASTER NAVIGATION WATCH TYPE AN5740 NAVY STOCK NO. R88-W-510 {HAMILTON}
10 AUGUST 1945; REVISED 16 JULY 1956
This has plenty of pictures of disassembly, and assembly in laymans terms.
It is 33 pages; 11X8 1/2 in. and has exploded illistrated parts breakdown, and pictures of step by step repairs, with illistrations and sequense of events of operation.
If anyone has time to makes copies available to members for free I am willing to donate this book
as long as I get the original back in a reasonable time frame.

Hi Mike,

Welcome to the 185! I could scan in a copy of the manual and provide it to IHC185ers.

Also, do have any parts for the 4992Bs? I am in need of a crown for a silver case.

I have lots of pocket watch parts - let me know if you need something, and I can check.

I would scan it and put it on the web here at IHC185, since that's my job. I scan at 300 dpi so if someone prints it out the quality will be very good.

UPDATE! HERE IT IS...

Frank; I will leave the rest up to you if that's OK. I'll send it USPS Priority.
It really is a super manual.
