Hi everyone, I just picked this up at a local thrift store, got it home and tried a google search. I didn’t find much other than it being made red 1925. Can anyone please tell me if the “562” stamped on the case is the movement number? Thanks Craig.
The 562 is the case manufacturing number. The case components at that time were almost hand made and it was important to keep the parts together to ensure a sound fit of caseback to middle case and bezel to middle case. The long number stamped on the caseback is the case production serial number, it dates the case to around 1930. The number on the movement dates the movement to between 1929 to 1934. Judging by the position of the regulator pointer, this watch is in need of a service.
By the way. I will give a free LIKE to the first person to correctly identify the caliber. Open to amateur researchers only (thus Erich, Yann, Francois and the other gurus get no like if they answer ). Clickety Click. Commence!
Sorry, no! I will think of a prize for the - true! - noob winner! Good idea Jim! Clue: this caliber can go into cases a little smaller than 30mm. Second clue: this particular version of this caliber does not have a click but a "spring click" underneath the ratchet wheel.
I always get these older movements wrong but I think I got this one ... then again, maybe I'm not newb enough to be allowed to guess.
Sorry, no again! But there are similitudes! Look closely at the barrel bridge and the position of the setting lever screw.
Well while I was sleeping I see the other side of the world has been busy. François is correct, one of the indicators is in the click (thus my comment "Clickety click"). Sorry @jimmyd13, but you're no longer a newbie . No, you're 2.8mm too small .
For this I have to cheat a bit, and call on Dr Ranfft for help. His wonderful guide suggest the following family members: 26.5 : bimet. balance 26.5T1: bimet. balance 26.5T2: bimet. balance 26.5T2 PC: bimet. balance, Incabloc 26.5T3: monomet. balance 26.5T3 PC: monomet. balance, Incabloc 26.5T3 PC AM: monomet. balance, antimagnetic, Incabloc as well as the Omega 26.5SOB T2 featuring a shock device, 15 Jewels @hoipolloi also has a nice writeup of the 26.5 family in this thread: https://omegaforums.net/threads/help-identifying-1920s-omega.8275/ Omega 26.5 SAV (1926) Omega 26.5 T1 (1932) Omega 26.5 T2 (1934) Omega 26.5 T2 PC (1938 -- I don't have the exact date) Omega 26.5 T3 (1940) Omega 26.5 T3 PC (1940) Omega 26.5 T3 PC AM (1942 -- I don't have the exact date) Omega 100 (1949) There are two cuts in the balance wheel, so a bimetallic balance...I'm unsure of the difference between the T1 and T2 variants (does the T2 have a shock device? or is that the PC variant?) so I'll venture this watch features a 26.5 T2 SOB.
Close enough! I think it is a 26,5 SOB, because of the special spring click, which I have only seen in this version. But nice deduction! For those who would like to continue the game: now the question is, what does SOB mean? Edit: I have just noticed that the link posted by Vitezi gives the answer, so not funny anymore!
To me those calibers are rather cousins of the 26,5 than brothers. There are similitudes, but the train wheel bridges are different. See for instance this 37,6 I have in my spare box: To me, the true brother of the 26,5 is the 35,5: But brothers are not clones! If the movement side is close enough, the dial side is different. To distinguish calibers, the setting lever spring is very often the key. Here all the keyless work is different. See below: 35,5 (with missing parts, from my spare box) 26,5 (with missing parts as well).
