Had the idea for some time to find one or both of these. Anyone? When were these made? What's the overview of the movement? I know the 7C is in the 7N family. So, you tell me. Image stolen from Ye Olde Web.

I don't think there is much of a relationship between the 7C and the 7N series.
The 7N series is just a group of economy quartz movements used across the spectrum of dress and sport watches.
The 7C43 and 7C46 were specifically developed for the divers they are found in. One of the big features is the high torque capability of the stepper motor. This was done partly to mitigate time loss due to the mass of the larger heavily lumed hands.

The instruction manual for the 7C46 is also for the 7N36, 7N85, and weirdly the V736. I haven't looked at the servicing guides to see if they're common or not.

I like those a lot. I almost bought one a couple of months ago... The only problem for me is the size. 47mm is just too big for my one chopstick wrists...

Seiko saves money by lumping calibres together in instruction manuals. Physically they are all quite different even if they function and are operated the same way. If you look at the tech guides for those calibres you will see how totally different they all are.

All these watches came out in a time period that I don't fiddle with much.

Yeh, the differ not only in physical design but some of them are not intended to be repaired; heat staked plastics etc. Calibres like the 7c43/46 are what I would call mid tier and are not only designed to be service but also have built in devices for regulation. I treat calibres like this the same way as a mechanical when it come to servicing; after all they are mostly mechanical in nature anyway. Before I got brave and dived into mechanical service and repair, I played with a lot of quartz watches. I bought lots of 50 to 100 pieces for pennies then revived as many as I could. A couple of the best running and most accurate pieces I have came from those $1 lots! I still have a couple of hundred that I don't count as part of my collection since most are just junk, although occasionally I pull them all out and do find one or two more that I manage to revive. Even working, most of them aren't worth what I paid for the original lots

Love the ashtray, never stumbled on a decent deal, though.

It's a shame seiko used a disposable movement inside something with some serious construction. Are new movements still available at least?

They are designed to be repaired and serviced 7dfe79adc2f0 Or were you meaning watches like the Sawtooth with the 7n modules?

Talk about timing. I just got my 1st one off the 'bay, and it arrived today: Not much in the way of opinions yet, it is comfortable I'll say. It doesn't seem to wear that large, I don't have the biggest wrists, and it seems fine to me, might be because the lugs are under the watch like so many other Tuna's. Worst part for me was briefly thinking in the poor lighting of my office that the seller had screwed me with a hour hand that had swept around and marked up the dial. I go 1/2 way to my car on the way out of work before I took it out in the sunlight to see how bad the damage was before I could see in the better light that the dial is stepped, and that was what I was seeing, not a damaged dial (old eyes I guess). Only issue I have is the case back says stainless steel, but the watch seems light enough to be a Titanium, still trying to figure out which case it is without taking a magnet to it or something.

Run a quick search for Seiko Ashtray and this is what I find.

Well i am trying to find a good parts 7c43 movement for my diver...i am told those are hard to find too...is this true?... I'm sure you're right. They're probably similar only in how their basic settings work. All these watches came out in a time period that I don't fiddle with much. Yeh, the differ not only in physical design but some of them are not intended to be repaired; heat staked plastics etc. Calibres like the 7c43/46 are what I would call mid tier and are not only designed to be service but also have built in devices for regulation.

Hey i think it would be amazing if you could be able to add that bezel to the 7c43 or even the 6309's...but i am sure that would be so costly..those ashtray bezels's are growing on me...like them... Had the idea for some time to find one or both of these. Anyone? When were these made? What's the overview of the movement? I know the 7C is in the 7N family. So, you tell me.

They are designed to be repaired and serviced 7dfe79adc2f0 Or were you meaning watches like the Sawtooth with the 7n modules? Your right I was referring to the N which I mistakenly thought was in the models pictured. Still it's a shame they're even used in the sawtooth.

That may be part of the reason the Sawtooth didn't sell all that well and had a relatively short manufacture period.

If your ever temped to sell please PM me..................

My heart sank when I saw that price on the linked to page. I wondered why I paid so much more for mine earlier this year, and in worse condition. I was oddly glad to find (as you'd mentioned but I missed) that they're no longer available. I was about to flip mine!
