Certina watch ,age about 1975.

[ottarno]

Hello everybody.

This i a Certina with battery whick I baught in about 1975 , gold duble,  cost 2000 NOK at that time . The problem is, not waterresistant around the knob any longer. 

Best way to fix ? rubber ring, grease or new parts around the knob.  

Also the watch dial is not new any longer, where to get new?

Whould like to renew it before I hand it over to next generation.

Thanks if anyone have knowledge about this watch.

Do you mean the dial is looking aged? I think you would be lucky to find a new one.

Close up photos of the movement and dial would be useful

Hello.

The dial looks dirty, I have open and washed with many chemicals without success. Is there any service-shops specialist on Certina?

What is the best grease to use when closing the house, silicone grease or wax of any kind. B

Imho the dial looks clean but is loosing its lacquer which is aged and darkened, albeit the lack of lighting isn't help. If so no amount of cleaning will solve that.

Hi   Cleaning dials with anything other than a damp cotto n but is liable  to a remiove the laquer, if its a water transfer  you could also remove the indices and chapter ring.  The crystal if polished will probably improve the look.  The movement is an ETA 956 111 I think as the numbers are indistinct. I have attached th technical sheet should you need some more information and or parts

Hello again.

Have cheched the watch and number is ETA 955111 if it mean anything for drawing  and also for the knob and waterresistance. Are there any box with different rubber rings for knobs on internet? Have tried to find without  success.

That is the model of the mov.t made by another company, it doesn't mean anything when working on case parts.

O-rings for crowns. Yes, there are assortment boxes and also available by size, for example from Cousins UK an even Ebay or Aliexpress. You need to remove the stem first, look at what is there, and measure with vernier calipers.

Hi  Have a look at these web sites UK, Cousins UK,  HS Walsh,  Gleave &co AG Thomas ar in th USA  Jules Borel, Esslingers.   on the Joles Borel site they have a database just look ip under the ETA 955111 and you will find the parts listing.  The stem /crown gasket is likely dried out/vracked allowing moisture ingress.  Cousins do Micro gasgets,  abd the best grease for the sealing gasket is silicone, also available at cousins.  you will lilely need another case gasket as well.

What becomes interesting for aged dials are they can actually bump up the value of the watch. Then cleaning of dials is not recommended they don't like to be cleaned. Getting a replacement would be problematic as it's not considered a replacement component by most watch companies. There are companies though that will refinish the dial and make it look like new.

Then from the photographs it doesn't really look like this is a water resistant case? It looks more like a dust resistant case. Which is probably why the dial looks as bad as it does. So basically if I'm right there isn't much you can do to seal this up to make it water resistant. Doesn't look like the crown had any gaskets originally and I doubt there was a back casket.

Interesting and aged dials can bump up the value of the watch - especially if it's an old Rolex Daytona or similar. But, for cheaper watches, it all depends on how it looks, and personal taste.  It's the same with classic cars - they never left the factory looking 'old and aged', but some think that's how they should look.

I've been looking for a replacement dial for a 60s Certina 23-20 for a couple of years - it looks "nicely aged", but has a scratch, which doesn't look so nice.

(I'm still not sure whether radium should be replaced on dials. I have replaced it on a couple of 'cheaper' watches I have, but have left a Universal Geneve untouched, so far)

Hello to helpers.

Have ordered rubber rings from UK to improve the waterresistance  and let it look aged . Thanks for help so far on this watch. 

Will send a new question of an old gold lady watch where spring is gone .

Have you looked first the crown to see what is has? If not, don't count on on the fact that any of the O rings from the assortment will fit.
