Chris AbellBoxed 4992B
Thougth I would show this off, just finished servicing it (one of my own finds). Had many of these in the past but never a boxed one, and mostly the ones I have seen are in the blue steel tins, how common are these wood boxed verisons?

Steve MiddlesworthChris,
That is awesome

I am going to presume that extra gear ourside the plates is for the seconds sweep to be in the center of the movement.
I am going to also presume that the hour hand makes one full rotation in 24 hours. I am curious, what gears do they manipulate to do that?

Chris AbellHi Steve,
Yes that’s the center sweep, I believe after the war, Hamilton sold conversion kits. They consisted of a minute and hour wheel to convert the movement to 12 hours also a dial and case back.

David AbbeChris, Great watch, I suspect by the overall looks of it that you had a easy time with your 16 point clean and lube and only a small "kick in the knickers" to get it up to par.
Steve, Three parts (generally

) govern the ratios of Hour wheel to Minute hand cycles. To make any "hours" ratio desired the manufacturer adjusts the "leaf and/or tooth count" of the Cannon Pinion (#1), the setting pinion (#2) and hour wheel (#3). This establishes the ratio of turns of the minute (#1 cannon pinion) staff makes to cause a full 360 deg. rotation of the hour wheel by the desired 12 or 24 times (hours) to 1. The movement pictured is a somewhat rare Elgin, but there are only small difference betrween these parts and the Hamiltons.

Steve MiddlesworthDave,
Thanks for clarifying that.....I see it now. I have never owned one like this. Did Illinois ever make them like that?

David AbbeHere's another "boxed" 4992

David AbbeSteve, as far as I know, only Hamilton and Elgin Made these, maybe Waltham . . .
Then of course there's the Longines (a different League, I can assure you)

Jeff EllisThat Longines sure is a cool watch. I looked some for one with little luck but don't think I could have afforded it over a 4992B. I had just bought a 4992B with the Silver case finished 4/30/1943. It should be ariving Wednesday...
Chris your is a REAL nice example of the 4992B! I love the wood box they were first used with. The guy at the NAWCC Library did not have a date for when they moved from Wood to Metal. Yours is a really good deal for who ever buys it. The repo wood boxes are $150.
