Morning guys, I've been trying to source any info on the orient cal.1946 21 jewel auto movement. Ive been unsuccessful over on watchuseek forum where they have a dedicated ( but quite possibly a very cliquey ) orient forum. 

They only seem interested in "what mako are you wearing today" threads etc and not actually helping out. That's my opinion formedover the last two weeks.

Anyway,  I will be in the process of stripping and cleaning said movement soon, now I notice the day date doesn't quick set, I have tried pushing the stem/crown in aka seiko, but it does nothing part from operate a lever that protrudes out of the movement around the 2 o'clock position.  The day/date will change when hands are rotated but that's it.

I've looked on the bay for a spare movement that I could look at but they all seem to have a pusher on the case for quick setting the day/date, my particular one has not got a pusher.

Is there any specific nuances this particular movement that I need to know before I start?

Any info greatly appreciated especially from anyone that's worked on one of these before.

As stated it's a Seiko 7625a. I have attached the parts sheet. I could not find a tech sheet but Seiko caliburs are built to very similar spec.. You will need to remove the movement ,dial and hands to inspect.I am not sure this caliber has a quick set facility.

Dammit I don't have one sitting around, ohwell not to worry.

I've worked out the quick set for the day, wind on till day changes then carry on till say around 2 o'clock then reverse the hands then go forward again till around 2 o'clock and the day changes, continue doing this till desired day is displayed.

But I can't find anyway of quick setting the date, any one got any ideas on this one

If that is the seahorse type movement you can wait till the date changes at 12 then move the hour hand back to 9 you may get a slight click then wind forward past 12 again and keep repeating. My Glycine works that way as well.

Cheers vic, that's how the day changes on this movement, but the date only changed when you constantly wind the time around, which I find unusual and something that would put me off buying a watch.

Sorry transporter,

I thought that my suggestion was different from what you had advised but if both methods produce the same result I guess its back to the drawing board

    • I believe @nickelsilver has a setup like that.
    • I posted pictures earlier in this thread. My lathe and mill are two separate instruments. I think I have seen examples of putting a milling head on a lathe bed...but not certain.
    • Timex Camper, September 1994, new to me. Strap is an old perlon with "Germany" in script etched into the resin on the tail end. Not Horlon or Eulit I believe. History unknown, running strong, losing less than a minute a day. Goals for this: Wear it a ton! Buy crystal lift, clean out the gunk around the ring and under the crystal Eventually swap into a stainless steel case. I've seen a member who has swapped a Timex mechanical movement into the Timex J.Crew quartz field watch case.
    • One of the problems we would have with a watchmaker's lathe is they were made over considerable span of time and manufacturing in the early days probably wasn't as good as it was today. Then if you look at the older catalogs typically it was just the head a few collets and something to rest graver on. So basically a basic lathe with over time things acquired but acquired things may or may not fit. Order today you purchase a used lathe that all kinds of nifty bits and pieces from a seller that acquired from? This would come back to that the basic watchmaker's lathe was used for basic watchmaking like turning things with a hand graver. Then limited indexing is fine because you can make things like stems Which don't need a whole bunch indexing   In the link above the word vector is mentioned and at the link below you can purchase one. Then of course you're going to need the motor that's a little bit extra for the price. https://www.hswalsh.com/product/lathe-vector-watchmakers-48-collets-hl11. That you're going to need some bonus parts like these found this picture online show the classic way of classic gear cutting.   The lathe could have a much bigger indexing disk but it has to be mounted close to the edge. Otherwise you're going to have a whole bunch of smaller disks like this which I think has notches rather than holes. Then as wonderful as these pictures look actually cutting a gear with this is not entirely fun. Look at all is belts all pulling on things and this is a watchmaker's lathe lightweight with lots of bits and pieces attached. It would make more sense if you actually cut a gear with something like this and it tends to be it's not really the best way to do it looks nice on paper but it is not the best way to go. Reality for cutting watch parts would be a bigger machine is much better. Than getting rid of all those belts and pulleys also good. Here is an interesting channel I would've liked of found a different video but this was nice and short if you look at his video as he uses a stepping motor and worm gear assembly for the indexing plate. In this particular video it gets attached to the lathe at about one minute and seven seconds and it looks like it's hiding looks like he has a Sherline. I do know he's had other stuff you'll just have to go through his videos to find it. Then at about one minute and 22 seconds you find out if you set up things appropriately. It's always bad we end up with half a tooth at the very end. Then you will note big lathe yes he's getting a big gear but you could easily cut a watch gear with the setup. And it definitely way more stable than a watchmaker's lathe.         Oh here's a company they been in business since 1911 http://www.fwderbyshireinc.com/
