Hi everyone, 

Recently I bought Certin DS 2 ref. 5801 300 from if I'm correct ~1970 with 25-651 mechanizm. 

I'm looking for some information about parts. I'm quite new in watches so may be that informations that I'm looking for are  obvious to you. 

So.. I'm looking for original crown or at least certina part number. 

In the internet I found crown for certina ds-2 that hase 6,5mm. But from my measurements it looks like it should have max 6mm.

And the next thing, crystal. 

I found some informations that it was sapphire crystal but I'm not sure, maybe you know the part number of crystal or dimensions, or haw to find it. 

I would be very grateful for any advice. 

If you need any photos I can add them.

Yes, please add photos.

Finding parts for vintage watches can be challenging, but not impossible.

Once we see pictures, you will get more input.

New members should give an introduction here. Though not required, I like to have an idea of member's location (Switzerland, Nevada, S. Africa...). Members of this forum are very helpful.

Thanks.  Sorry...I missed your intro--my bad! 

I doubt that watch takes a sapphire or mineral crystal.

I think that crystal is too small becouse I can easily push it out by hands. 

Crownt original and I think that it is to big and it stick too far out. 

My dream is to have it waterfroof as mutch as I can. So good crystal and we'll fitted crown is wery important

"The Certina DS-2

Introduced in 1968, the Certina DS-2 carried on this tradition of robustness and maintained the DS system with improvements and a more durable stainless steel case design. These tonneau-shaped cases shared the turtleback feature and some further innovations. The crown is partially guarded by being set within the flow of the case flank, and it is secured with a twin seal."

https://www.fratellowatches.com/the-certina-ds-and-ds-2-vintage-value/#gref

That's the text from that site. My crown isn't sitting flat and it doesn't have seals so that's why I wish to change it. 

I'm considering this one but I'm not sure will it fit and that is why I seek for some advice.

Ok after loong sherch I found post on some forum that crystal is: 982/10 31.0-13 but it is really hard to faind, but it would be grate if someone could assure me that I'm not wrong. 

"
DS, 31,0-6 and DS-2, 31,0-13 packages. It says DS on the DS-2 one but this is because it was used on the later DS watches as well."

Thanks for that informations, I will look for that crystal. 

One more think.. Normally under the acrylic crystal, and as far as I find out today it is acrylic, there are no gasket but this watch should be somehow water resistant. So.. Should there be any gasket?

For acrylic crystals, I have never seen a gasket. I don't expect I ever will. GS makes various waterproof crystals, e.g., magnitite.

No gasket, but tension ring. This original crystal for DS/DS2 is much thicker.

      Just wanted to introduce myself

      By mattlikesvintagewatches · Posted

      Hello everyone, My name is Matt and I like vintage watches along with pocket watches. I'm very new to the hobby of watchmaking, I've only been tinkering for about 2 months and I'm happy with some of the projects I've salvaged.  First I repaired This Waltham 17 jewel 18s and that was fun.  Then I repaired this old Zenith movement with 19 jewels. I couldn't find it on the pocket watch database though.  Then I repaired this one Lucerne 1 JEWEL movement. It was actually the first watch I got but it was so difficult to put back together with the fiscal amount of tools I had at the time so I just left it strewn in a Ziplock bag. Then My most recent project that came up a total win was this Longines Caliber 19AS, 17 jewels unadjusted. It turned out beautifully in my opinion and was by far the most difficult to reassemble.  I am in love with this hobby and its kind of engulfed my personality as of right now.  I plan on giving the Longines watch to my uncle, and so right now I'm trying to enjoy that watch the most I possibly can.    What I'm currently working on: A Seiko Automatic with a little date window and a weekday function too. I think its the 6309A.  Then there is this Omega pocket watch. Unfortunately I lost a little screw that held in the click spring. I'll have to source another one because its tiny and my room is filled with carpet, that thing is gone. Then theres this little tiny Elgin pocket watch. It's fully assembled but the amplitude is low and so I think it needs a new mainspring.  Then theres this Waltham 7 jewel movement that I also cleaned and reassembled, but it'll only run facing one way and again with the amplitude being low, I think it needs a new mainspring as well.  And finally, I'm working on this gorgeous Grade no.3 1883 Waltham Pocket Watch. It came with a broken balance staff on both sides and would only run when the watch was like sideways, crown to the sky. I'm really excited about that one though, might be worth something.      I've chosen to not show the other ones because they're not in movement holders right now, and the Omega is not put together.  As you can see, I take these pictures using the flash. Idk why but I like the way the flash makes the metal shine more than just my little lamp.  I'm also very eager to find a replacement for that balance wheel; any links would be appreciated.  From what I could tell on the Seiko, it's just dirty and It should run if I put it together carefully after cleaning.  Also, I fear that that 1883 Waltham may not run too good because of the mainspring, it's probably set because it's so old. I may seek a replacement for that too. I also need to find a crystal for that 18s gold filled Waltham that I've put together. It's just scary having it exposed.      I ALMOST FORGOT to mention. Is this Omega real?      You gotta turn your head a bit but it does indeed say "OMEGA", so I'm confused. I never knew they made pocket watches. And thats why I'm skeptical. Please let me know.    But thats pretty much it. I just wanted to put this out there so that I could begin using the website properly and also to let some people know I exist I guess.  Also this is my second account. I know that may violate some rules but I did the introduction wrong the first time and I wanted to fix it by making a new account. Please don't ban this one.    Thank you all, -Matt

      Chinese clone demagnetizers

      By mikepilk · Posted

      Sounds like you and @VWatchie were unlucky. Mine has been running on 230V UK for years  ( it's been 230V for many years @Neverenoughwatches, not 240V).  Though I have had to re-solder some wires. When I buy cheap Chinese electrical components I often take them apart to check they're not going to kill me. Since the demagnetiser, I bought a cheap fish tank heater for my plating set up. Plugged in, big flash and smell of burning. Deader. So I bought a cheap cup heater plate. Exactly the same - flash, bang, wallop.
