I stumbled across this article that makes an interesting WIS read - grab a beer and 20mins - the history and uses of the humble 7750

Surprising ebauché for multiple brands and styles. Congrats Capt!
For the sake of a newcomer - what does WIS stand for please? It is not a term I have come across before.Quote:

When in good health the amplitude is over 290 degrees and positional variation is close to or within COSC spec. They may be ubiquitous but certainly not humble in my view.
Two things I don’t like: the movement us quite thick so any watch using it will be a bit too chunky for my taste, and I dislike the way the rotor can spin backwards thus producing a wobble.
I love the 7750 and it’s derivatives. In many ways, you have to wonder if the Swiss watch industry would begin such rude health today if the tooling hadn’t been preserved.
I sold my only 7750 engined watch recently, and as a WIS I really think I should by another 7750 to take its place.

It is definitely the workhorse movement of the industry.
I'd like a 7753 variant, as I've got a flieger style vanilla 7750 already.
I’ve had a couple of 7750s and there was something about them that felt very solid.
However, as [mention]walkerwek1958 [/mention] mentioned, both were quite thick and ultimately, that put me off and I moved them on.
Trouble is, I do like a mechanical / automatic chrono but at the affordable end (where I do my buying!), there aren’t many other options beyond modulars and a seagull. I’d like to give one of those a shot at some point too.
The experience you get with a 7750 is nowhere close to that of a seagul or a modular 28xx base. I have 5 7750s with three of them being tudor big blocks and 792xx and wouldn’t change themQuote:

I always found the legibility of the 7750 poor, for the simple reason that the chrono-minute counter is located at 12, and I would often have to be peering round the main minute hand as it swept over the sub-dial.
Dunno why, it so often seemed I was interested in the first minutes of timing something that started near the top of the hour. I guess a lot of sporting things start on the hour or the half hour (when the same thing happens at 30 minutes in.
This was especially true for a Damasko I had, but they have really large H and M hands.
However, the 7753 (I think) where that's been moved to a proper Compax layout position at 3 is much more attractive.
Yes, I love the wobble too…Quote:

In my opinion the 7751 is a gem, with its triple date and moon phase, in addition to its 12 hour chronograph function, it is an entry into serious mechanical watch complications at a relatively modest price point.
This is the Longines:

I personally love the iconic wobble, though I have to concede they are rather thick.

damasko fixed that with the DC8x series! I guess sinn and Tutima did also…Quote:

Always try to keep a 7750 in the collection. I like the wobble, part of the charm!
Two of my favourite watches are 7750 powered so I won't hear a word against them.

My very first automatic watch that I had promised myself for many years to get when I was 40.
Never wear it now but still have it and after a full service a few years ago it remains tucked away.
A cracking watch and as we all know such a robust workhorse movement.https://uploads.tapatalk-cdn.com/202...9ce56d7c54.jpg

Love the wobble!
Such a versatile movement.

Interested to know what is the most expensive and most economically priced watches with 7750 movement within.

Only the one 7750 in my modest collection.https://uploads.tapatalk-cdn.com/202...76155ce12a.jpg
It’s a good question.Quote:

Good article, thanks OP. My one and only 7750, love the wobble! I do agree with sweets on this occasion in preferring the 7753 personally.

I am a fan of the 7750 and it’s derivatives, in some ways it helped the watch industry fight back against the quartz crisis
It made mechanical chronographs ‘affordable’ again, it helped Panerai expand its offering, it’s been used in some humble and not so humble watches and has even been used in space numerous times.
Yes it is thick, yes it means watches tend to be 41mm + in diameter but along with the ETA 28xx line of movements it’s hard to think of another movement that has had such an impact on the modern watch business. It’s also not a bad looking movement when given some blued screws and a bit of finishing - the same can’t be said for the 28xx, any Seiko or Miyota
I love 'em...

Had a couple of the years and always found them reliable good time keeper but a tad noisy.
I have to admit this thread made me put this one today which has been sitting in the safety deposit box for over a year…https://uploads.tapatalk-cdn.com/202...7a800fff18.jpg

Is that a 79170?Quote:

Indeed 79170. Amazing watches but most of these have been polished and lost the amazing factory chamfers. I was lucky to get this unmolested example 6 years ago before things started going crazy… this and my ezm1 would be the last watches to ever leave the collectionQuote:

I think I’m right in thinking that my Omega Mk40 has a derivative of the 7750, and it’s been accurate for me. I’ve also grown to kind of like that ratchet sound after the wobble too… it’s quite surprising how much the watch moves around on wobble!
