Hello All;

About a month ago I bought a lot of 4 movements, for spares or repair, on eBay. Three of the 4 movements were AS-984, two with 15 jewels, one with 7 jewels. Two of them had broken balance staffs. The one with a good balance was a semi-runner and even after a service, it stopped in certain positions. Long story short, I threw all the parts on a pile, sorted the best which fitted the 15 jewels movement, and build a movement which runs very, very well. It's within 2-3 seconds a day. In fact it runs so well that I like to find a case for it.

My problem is finding one, as on eBay, and other watch-parts sides, you'll find lots of loose movements, but for some (to me) odd reason, hardly any cases can be found.....are they all thrown away, all to different in size to be kept or am I looking in the wrong spots?? How does one go about finding a case?

As said, the movement is AS-984 and the dial diameter is, like the size of the movement itself; 23.7mm. Probably a men size at that time, now considered more a ladies watch.......fine with me.....

Can anybody give me some advice how to find a suitable case........

Thanks on beforehand ;)

You can probably use a bigger case if you have a spacer or a movement holder. Most important should be the stem height. From dial to center of stem.

@rogart63 Top dial to center stem is 2.5mm.

@szbalogh There are plenty of vintage watches from India, but they seldom mention the case size, never mind the internal dimensions........or am I mistaken?

Hi endeavor,

As Roger just said, the stem height is very important. You can always make do with spacers for the rest. I think you can sometimes manipulate that height with a shim if too short and even with a thicker dial...but it is all limited to how much room is left for the hands on top. In my mind, I would check according to the specs below. Remember the height given is just the height of the movement not the stem height. The size is for a medium size movement so to speak: either men or women. It is helpful to know this height in order to calculate the clearance from the top to the crystal (based on the cavity where the movement fits) -- just add the pinion height for a total height -- since you don't want to have the watch hands rubbing against the crystal. Hopefully ebay may have several options...check these specs against the original movement specs of the case you decide to get.

PS. I don't do this much -- or almost never for "uncommon" movements vs. available common cases (virgin) -- so just my opinion.

Lots of good info already to consume and........ digest......... :thumbsu:

I love drawers.... Roger ;)

 

Found one that could work? Pretty small with 16 mm lugs and 24,3 inside. Brass with chrome. PM ? Not sure what you look for? I will just find the case back.

@rogart63 I did send you a PM ;)

@szbalogh Interesting "speedtimerkollection" link to watch cases ! So here is where they all end up !? Opens new possibilities if one has a nice movement, but no case ! Thanks !

@bobm12 Thanks for the info ;) I found similar info already, but for a case I didn't realize the distance from stem to dial ........ obviously, once pointed out........it makes a lot of sense :)

No idea yet how to order these spacer-rings and which dimensions are required, to look out for. I think CousinsUK have a lot in stock.........

Them rings are customizable. You can "resize" them with scissors and such. Make sure they are for the movement size though.
