·A tuning fork model, runs at 300Hz so the sweep second is smooth. Nicknamed a hummer since the 300Hz tuning fork can literally be heard humming.
A cool, if not slightly delicate bit of technology first pioneered by Bulova if i remember correctly.
isn't that electronic model? like this

·I love these c-cases, but I’m not sure I’d agree with that. The 1803 comes in plenty of dial variants and people used to collect them like crazy similar to the way some now collect C-cases.
Constellations' world is bigger. Different kind of cases, different materials on dials, different colors, different bezels, bracelets and straps. All of this in variants yellow and rose gold with 751. If you go to steel and gold capped is unlimited.

Sorry I can't edit my post, so this photo is from this forum from an old post, apparently the movement of these watches are under license from bulova itself, not sure if this is similar to bulova's accutron watches
reference number 198.002 for the c-case electronic.
I saw one Omega electronic for sale but with ref number 198.001, so a different case

usually these c case constellation white gold (meaning white gold fluted bezel) versions that i see for sale, use a 1021 movement rather than 7xx 5xx movements, do you think that matters?

·unfortunately it really does seem like the 1011 and 1021 movement models only got pretty boring dials, I have only seen vertical brushed in silver, gold or blue, with the blue dials aging pretty poorly from tritium burn (well im pretty fussy but im sure some people wouldnt mind them)
I still picked up a 1021 with a WG bezel when I found one going cheap so with my 751 WG bezel...
but I can also one up that because I actually have 2 identical ones same dial config even...
It started life as a rusted blue dial, but after restoring the movement to running I was always annoyed at the dial, and when I found a dial and hand set, I just needed to make it complete.
198.741 is the actual hummer C-case, though there are other varieties that are still c-shaped for the f300 movement.

·Sharing this Omega memomatic in C case but not a constellation, it is actually a seamaster in C case, which has been tempting me for a while now.

·Collection with the same calibre, I think
- .016, .019/029, .045 is great 👍
- 1803s with different faces is boring 👎

·This memomatic is not c-shape, it's tonneau-shape.
my bad, maybe I'm just blind. I can't tell 😎

What's the difference? Genuine question, not rhetorical. I've been curious about how strictly we should define "c-case".
I see loads of slightly different c-shape / tonneau shaped cases from various manufacturers in the early 1970s in particular. Some are a a bit chunkier (wider in relation to their length). Often these ones (like the one above) have the space between the lugs straight-edged horizontally. Some "c-shaped" cases have the space between the lugs extending all of the way back to a curved surface that has the same arc as the dial. The Constellation c-shapes are somewhere in-between.
Here are a couple of Longines Ultra Chron cases - would you say that the first one is c-shaped and the second tonneau shaped? At what point does one become the other?

I don’t know the answer but I’m also curious and I’ll add in two of mine for expert assessment

Here's the one you’re referring to (saves clicking on the link) although I have to say that I’m a little surprised by the shape of the crown, but to my eye whilst it may be an original design, the case doesn’t look very different from my obscure Perona.
The Perona may well be a fifty year old 'homage' (if they were called 'homages' in the 1970s) but it does seem to me to be C-case nonetheless.

I don’t think there is anything wrong in calling similar case styles c-shapes as long as the point isn’t stretched too far ( the memomatic and second ultrachron above for example are c-ish but not c-shape IMHO)

·I recently acquired a date only 561-751 cal. C-Case as well, but it’s the same joke, a 672 ladies version 😀
I’d decided not to buy one however seeing one with a WG bezel in awesome condition, I just couldn’t help myself and overpaid quite a bit too, beyond my original limit
