·Hello fellow members of omegaforums,
Today I’d like to share a watch I previously asked about in the group, and thank @mac_omega for correctly guessing its caliber.
At first glance, when seeing the beef lugs, one would probably think of a Seamaster from the 1950’s.
Here’s an interesting piece I’d like to share.
From the movement number, it looks like it was made in the early 1960’s, which puts it in the Seamaster pre-De Ville era.
If you’re into Omega De Ville watches (including the early pre-De Ville period), you should definitely check out this great thread - it’s packed with useful info: https://omegaforums.net/threads/the-ultimate-seamaster-de-ville-thread.159035/
This watch is something I have not been able to find anywhere else online.
It is reference 136.001, using caliber 610, which is a manual-wind movement. Since I couldn’t find any information about whether Omega reference 136.001 was originally paired with cal. 610, I asked the expert in the forum, AI (@Archer). He kindly replied: “That case is listed for the 610” and even provided the document: “055ST1360001 | STEEL CASE CAL. 610”.
⸻
The watch itself
This is an Omega ref. 136.001-62 SC, cal. 610.
The case is unusually large compared to typical models—36.5 mm excluding the crown.
In my opinion, the case is unpolished, with the original circular brushed patterns on the caseback still clearly visible.
The crown is a thin scalloped type, consistent with Seamaster / Constellation models of this period.
The inner caseback also shows a uniform circular-brushed finish.
One point of interest is the six caseback notches on the outside (used for opening the case). On regular-sized cases these notches are closer to the edge, but on this larger case (my watch), the notches sit further away from the edge.
The movement number is 20,516,xxx, which dates it to around 1962–1963.
Please also note: when a caliber is housed in a larger case like this, a movement ring is required to lock it in place (as marked by the red arrows). Moreover, the larger case also requires a longer securing tab (as marked by the green arrow).
⸻
The dial
• Features an uncommon ‘waffle’ pattern.
• Clear close-up of the fonts.
• Close-up of the date window.
From my research, I could not find any examples of this reference online internationally. I have only seen two other pieces shared on Facebook. I will not comment on the originality of the dials on those two.
Example 1:
Example 2:
However, looking at the similarities in the caseback notch spacing (same as mine), the movement numbers (in the 20 million range), and the same reference (136.001-62 SC) across all three watches, so I believe this reference truly exists in this unusual jumbo case and was produced only for a short period.
⸻
As always
With very uncommon watches, I show:
• The full dial, removed from the case.
• The reverse side of the dial, showing original machining marks and both intact dial feet.
Finally, here’s a wrist shot.
⸻
If anyone owns, has seen, or has information about this reference 136.001, please share.
Thank you very much for viewing, and if possible, please click “like” to support my research efforts, and share your opinion about my watch. 😍
