Help identifying vintage Concord watch

[thewieds]

Hi, Looking for some help to identify vintage Concord I bought from estate sale last summer. Any info on age or model would be appreciated.

That's got an interesting design in that it seems to have a dust-cover that needs to be removed before one can ID the movement. I can't tell if the stem/crown have to be removed first, but there is a detent screw visible on that back cover. It looks like there are indications that previous watchmakers have removed/installed that stem with the dust-cover in place. In other words, odds are that the stem must be removed first. This can get tricky for one who isn't used to working on watches. If the screw is loosened too much, the set-lever might drop off behind the dial. This would necessitate removing the hands and dial. In other words, it might be a bit of a can of worms.

That said, if you do carefully loosen that screw 1 1/2 to 1 3/4 turns, the stem should come out. That may allow you to remove that back cover. I'm doing a bit of guesswork here because I can't see how that cover is attached to the back of the dial. It does look like it is somehow.

Maybe one of the resident experts like roughbarked will recognize the design and advise you on what to do, or what not to do. Whatever the case, identifying the movement isn't much easier with this back view than it was when it was still fully cased. Good luck.

If you undo the set lever screw you can see through the hole in the dust cover. It only neds a turn or two to loosen it enough to pull the winding stem out and then the dust cover will fall off easily enough, so that we can see the movement.
Concord always bought the better movements and I'd say it has an ETA movement. Possibly 717 or 744?

I took it to my watch guy and he remove stem to get the cover off. Attached are pics of the movement.

I'm stumped on this one. I'm guessing that it measures about 18 x 27mm? roughbarked ?

If you can see it, you'll note that though Ranfft uses the same image for a group that may have had plate changes but nothing else changed, this one has the holes for the pins and screws to place the escape wheel cock in two different positions.

Complete with his typos:

Several bridge layouts (cf. examples)
differences not known between 717-719, 724, 726-729,
likely just catalogue designations for the varying bridge layoouts

Therefore it is likely that ETA 717 which I mentioned in my post earlier. Note that 717-719 were deemed the same.

Thanks for all the help!

Hmm...I guess the new system doesn't allow partial quotes. If it does, I didn't figure it out.

Anyway, I see similarities between those movements, but there are also what I see as significant differences. For instance, the click type and location, the shape and placement of the escape-wheel cock, and the shape of the balance-cock. I'd love to see what the keyless works look like under the dial, but that may be a lot to ask.

Now that roughbarked pointed out the steady pin holes, etc., that would allow for placement of the escape-wheel cock at the different location, it makes more sense. I didn't see that without magnifying more than my monitor does by default. It looks like another winner for roughbarked. That's why we pay him the big "barks". ;-) Cheers.

Thanks again. How about help with age on this Glycine? Movement is a model 99

 

[MrRoundel]

I'd call it a Glycine caliber 29. It's a good match in Paulson's movement ID book. As far as the year goes, I don't know.

In looking through this book, I have noticed the Glycine movements. They look like they made a very nice grade of movement. This is one such movement. Good luck finding the year. It may be best to just find out when the tonneau style of case and movement was popular. Maybe 1930's and '40's? That's a bit of a WAG.

Again, the holes for changing the escape wheel cock are there. The shapes of the plates may be altered or skeletonised but the positions of wheels remains the same.
Eterna often put the ratchet wheel under the barrel bridge.
