Thanks..
I learn a lot here!
I guess the conclusion is, it is a 18''' variation of the cal. 19''' properly a standard grade B. According to Omega a 18''' is 40,7 mm, and the cal. 40,6 was actually only 40,0 mm i case diameter (and was first made in 1923).
According to Omega there were in 1906 379 different variations of their movement!!!
I guess it is not a railway edition, but i have actually seen this ingraving several times before.

Help to determine Omega pocket watch caliber
Hi! I also collect Omega pocket watches . Most often you can see the caliber number stamped on the movement , but on this one I can not see it . I've tried a find a similar and my guess is Cal . 19 LOBNN , but would like to hear what you think . ( see bel...
Hi Thomas, I would like to know...
Hi Thomas, would like to know the exact diameter for determination. Might have been designed for railway use due to the back - but what makes me uncertain about that is the very low number of jewels - none to be seen on the wheels... kind regards erich
I guess it is
A calibre 40.6 L 15 p then? But they do not have a pattern engraved like the 19'' and the 19'' is 42,7 mm according to Rannft ?? Best Thomas
ref. identifying
Hallo Thom. This is the very movement which made Omega famous; when it was introduced (size 19''') it was actually called caliber "Omega" (the wellknown story about the namegiving by banker Rieckel). It proved to be a big succes and within a couple of yea...

some photos of a DDR
This is actually my grandfather's watch, given to him for Christmas 1911. Serial number 2,584,723 made in 1905. I always thought it was an incredibly beautiful watch even as a young boy but the more I read about it the more I realize how special it is. ...
Thanks very much for sharing your DDR with us, Fred. Thomas' [tdn-dk] thread is some nine years old - could you possibly . . .
. . . start a new one? If you need assistance, please send me a pm. Here are images of Steve G's DDR . . . . . . acquired at Omegamania fourteen years ago. I'm not a pocket-watch guy, but would jump at the chance of adding one like this to my wristwatch c...
The engraving on the back cover looks very much . . .
. . . like the original logo of the Indianapolis 500 Motor Speedway, Ben. Perhaps it was an official's timekeeper, if not an official one.
swift wheel..
Thanks, and that would not be half bad Art ! For a prof. timekeeper or for any time-keeping purposes you would however expect a little more than a bog-standard bread&butter movement, isn't it? The engraving shows a winged wheel with spokes, some kind ...
