Ricoh Cal 580 'Riquartz' movement


Recommended Posts

Hi

Just started looking at my Dad's old Riquartz. Cal 580 5 jewel quartz. He passed away 7 years ago. He got the watch around 1980. It's been sat idle for that time. When he last wore it I remember him complaining the day/date stopped working.

I put a new battery in today. The watch "goes" but indeed the day date is stuck. If If I  fiddle with the crown I can  move the day... but it will not move the date... and both stay stubbornly still despite moving the hands through 24 hours +.

The "seconds zero" function with the inset button at "2 o'clock" sort of works... however the seconds hand moves to the 1 o'clock position... and stops.

Is it possible to get a replacement movement... or is there a chance this is repairable?

Thanks!

To be specific....I'm trying to find some schematics for the movement. For example it is not easy to see how to remove the winder stem. Basic stuff I know... but if I can get the movement out and remove the dial I can do some gentle investigation. 

I think at some point dad probably took it to an inexpert watch repair shop to change the battery and someone did something clumsy and that may me the cause of the woes.

Apparently there is a hole in the pcb with a release button within... I will try to find this.

The service manual is available from the AWCI... however... I don't think at this point $150 membership to get access is an option for me!

This could possibly be the setting lever release button as it looks countersink and sits near the stem. Push it gently and if it flexes somewhat I think we can be pretty sure. If that's the case, pull the crown out to its setting position. Then push the button while trying to pull the stem out. Don't use force!

I made a small effort trying to find some documentation for this movement but no luck.

You either have to join a new Association or find a friend? We need somebody who's a member of AWCI and they can download the tech sheet and the parts list.  the second link has the parts list.

    • That's the right technique Mal 👍 If you are ok with a loupe ( which I'm not ) then pick up the dial in your left hand and make a tripod holder out of 3 fingers and then exactly how Mal and me described with your right hand, press and flick out the stem at the same time. You need three fingers to do this, i use my ring ring finger , sounds like mal uses his little finger, just whatever you feel comfortable with. The key point and dangerous side to this is the tweezers or driver slipping off the release screw. Stablise your left arm by resting your elbow on your bench, so that you can hold the movement horizontally flat, use a x5 loupe to view  and good light so you can see well and have a good tight fitting screwdriver to push the release down. Or as suggested a pusher mounted solid upside-down somewhere then all you need to do is push your movement up to it. I'll rig something up in a bit to show you what i mean.
    • Thanks Michael, shes a real soldier, it would take a tank to knock her off her feet.  Shes surprised even me and i knew she was a tough cookie.  Good for you Michael, you keep at it. I've been reading your posts re. your watchroom they're inspiring and it doesn't matter how long it takes you to get there its about the journey. Rome wasn't built in a day, our watchcaves are our solitudes, our own little empires where we can shut ourselves away from the crap that goes on around us in the world. I look forward to seeing you progress, I have my own ideas how i like to do things. But in answer to your questions on that thread, just let your workspace evolve around you and how you work. You wont figure it out straight away but you will know when to change it and when to leave it alone. But most of all just enjoy it.
    • That can be tricky. Sometimes I hold the movement from the edges in left hand and with right hand I push the release with tweezers and simultaneously pull the stem out with right hand pinky or something. 
    • I see what you mean. I must admit I’m not entirely comfortable with that but I can’t see a better method than what you suggest. I’d like to see something like this mirror with a short spike: https://www.cousinsuk.com/product/mirror-for-observing-movements Place it on, push the spike on the post with one hand and release the stem with the other hand. Minor problem, it doesn’t exist.
    • Hope you mum keeps on mending. I was adamant that I was going to get myself going after my stroke. I was only 52. I still have a lot of life left to live. Some people give up. Some people don't let it beat them. Your mum sounds like one of the winners. 👍
