Ricoh Cal 580 'Riquartz' movement

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.

      Setting lever spring

      By RichardHarris123 · Posted

      I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong.

      Ah ok yes that makes sense to polish it where the arm starts to form from the body of the bridge, i thought you meant the underneath of all the arm.

      Epilame / Fixodrop

      By JohnR725 · Posted

      this is something I've never quite understood about the some of the Swiss companies. In 1957 Omega was using 9010 for the keyless parts with epilam. there's been a slow migration towards using heavier lubrication's but still typically oils and epilam to keep them in place. When it seems like 9504 works so much better.

      Is this a 'hack' ?

      OK, welcome in the world of alarm clocks... I guess the 4th wheel is dished because it is from another movement. If it was not dishet, then it would not mesh with the pinion of the escape wheel, am I right? The marks of wear on the 4th wheel pinion doesn't corespond to the 3th wheel table position, at list this is what i see on the picts. Calculating the rate is easy - there is a formula - BR = T2 x T3 x T4 x T5 x 2 /(P3 x P4 x P5) where T2 - T5 are the counts of the teeth of the wheels tables, and P3 - P5 are the counts of the pinion leaves. Vibrating the balance is easy - grasp for the hairspring where it should stay in the regulator with tweasers, let the balance hang on the hairspring while the downside staff tip rests on glass surface. Then make the balance oscillate and use timer to measure the time for let say 50 oscillations, or count the oscillations for let say 30 seconds. You must do the free oscillations test to check the balance staff tips and the cone cup bearings for wear. This kind of staffs wear and need resharpening to restore the normal function of the balance.

      Any tips to correct a sloppy error?

      By RichardHarris123 · Posted

      Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue.  Maybe someone will have a better answer.
