Certina 0821 449 ladies gold watch 1970 (ish)

Well gentlemen, here I go again. EtronX does things he does't know how to do...
 
To make a long story short:
 
I have always liked wrist watches. Lately I have bought a few. And lately I've dug up some old ones. They have been laying in a drawer for years.
 
I have also always wanted to be able to take a watch apart, clean it, oil it and put it back together. So now I have bought some basic equipment and taken an old Omega ladies watch apart. It did not run before I took it apart. Thats in another post. Looking for a glass for that one. Then the plan is to put it back together. Hopefully running again.
 
So to the matter at hand. The old Certina after my mother. It runs, but the glass is pretty worn. I took out the dial and movement without problem. The case and bracelet is beeing cleaned as I write this. Again I have searched the interwebs for info on the watch, and again I came up a bit short. Well I found a good description of the caliber. The Certina 13-21. So far so good. The problem is the case and the glass.
 
Can anyone please guide me to a place where I can get a new glass for this watch?
 
Attached is some pictures of it before cleaning.

The crystal looks like it could be polished. A little small but tape the case for protection. Lot of threads on polishing acrylic crystals on the forum. I see one problem . The crowntube is a little deformed. That has to be changed. 

If you like to change the crystal anyhow you could probably use a Sternkreuz  ATC  crystal.  With gold tension ring.  You have to measure the old crystal and order one in the same size. 

Cousinsuk is the best place to order from i think.

If you want to know about the watch, the serial number is the long number 8 million dates it to about 1970-1971.

The other number is broken down as follows the first two digits are the code for the movement used 08 was used for calibres 13-20, 13-21, 13-22 the second two digits 21 are Certina's code for a stainless steel case with gold cap probably 18 ct but could be 14 ct.

The other number 449 is the model number.

Thank you for the reply. I'll check the crowntube. It looked OK when I took it apart. The photos are taken on an iPhone through a loupe. That might give some distortions.

I went into Cousins and looked there. Tried to search, but found no info or parts for the 449 case. I'll try some more.

You don't need to search for your specific model as you won't find one. This watch has a generic acrylic crystal like most vintage watches.



Roger that. So I guess I just measure the diameter of the glass and order the same size then.

Thanks for the reply.

Normally there are many types of crystals so you should measure a couple of things. Crystal diameter, diameter, thickness and height of the gasket provided it has a gasket. Some have an internal tension ring.

Be sure to get the one that is similar in type to yours. Wouldn't necessarily be a problem if you ordered a different one but I'm assuming you wanna go for originality as much as possible.

You can try and order a crystal that is 0.1-0.2mm larger in diameter than what you've measured. If it's slightly too big you can just sandpaper the edge a bit.

    • Latest project was a non-running ebay purchase with an FHF70 movement. I stripped and cleaned it, reassembled it, and got it running. So far so good, nothing damaged AFAIK.  I was oiling the top jewel on the balance (the one in the cock) which was a slightly unusual shock setting. I removed the spring (3 leaves) which was part of a chaton holding the cap jewel. This left the hole jewel behind which I retrieved with rodico and then lost it. I was taking it off the rodico, very gently as I thought, with tweezers, and then it just disappeared.  Fast forward a week, I got a donor movement, non-running, with the plan to just take the shock jewel that I’d lost. It was the same movement but had standard incabloc settings, and was steel rather than copper/brass.  I changed the cock and balance complete and it ran, not very well. I switched the lower jewel setting, cleaned and oiled both jewels and the replacement balance. Without the pallet fork the balance swings very nicely with a puff of air. With the fork in place, balance out, it flicks side to side nicely with power in the mainspring.  Put them together and it doesn’t run. The impulse jewel sits in the fork and it stops.      Any suggestions how I proceed? In case you didn’t follow that I have 2 FHF70 movements, nothing broken as far as I can tell, but mixing up the balance wheels and jewel settings results in a non runner. 
    • Oh and this almost perfect third wheel pivot and slightly set mainspring  Ah ok yes i see what you mean, good idea. I'll try that if i fluff this one up. The image isn't great quality but i like the idea though.
    • Why cut the paper, cut a square around the image and grind to it. 
    • I did try that last time Rich , i traced the image from the Bestfit book which is the actual size. But its more difficut to cut the shape from paper than it is to grind the steel to shape. This way is pretty easy and the final shaping is done when fitting the part. There are a couple of things i will do differently next time, clamping the 2 pieces together with a drill press will help to hold while scribing the shape in. This was a bit tricky having only one hole, if using the pins and cork the drill size needs to match the pin diameter so there is no movement at all from the template. This movement hasn't finished frying me yet, damaged thread in the plate crown wheel hole and two rubbed in cracked jewels, thats gonna be much more fun.
    • 👍 Whats not to follow OH ?  You're every inch a pro and a true gent, i always enjoy reading your answers even some of the clock stuff that i dont have a clue about.
