Omega 3570.50 / Question regarding 1479 bracelet w/812 endlinks

Hey all,

I recently did some research and decided that I would purchase a 1479 with 812 endlinks as I had read that said endlinks would fit without any modifications.

Well, today the bracelet and the endlinks arrived and to my dismay the curvature of the endlinks do not seem to fit with the curvature of my 3570.50 case. Because the fit isn’t snug, there is no chance in getting the end links to fit and I do not, of course, intend to force them in.

So the question is, do you think the endlinks could have been altered in any way or is the radius of the 3570.50 different to its predecessor? I am pretty clueless as to how this could be the case.

Please find attached two pictures where you can clearly see the gap between the case and the endlinks. This is caused by corners of the endlinks fitting snug into the case, but the gap progresses at it moves towards the center of the link. Interestingly, both links appear to have a different radius. Thoughts?

Best regards,
S.

You have to file the end-link ears so that the end-link moves farther up and into the lug opening and the holes all line up. Had to do it so that they would fit my 3894.50 and now it fits my 145.022-69, also.

Thanks for your reply.

It appears to me that the lugs of the 3570.50 might be appx. 1mm shorter than the lugs of its predecessor. Unfortunately, I do not think that I am going to be able to mount the bracelet without modifying the endlinks, which probably isn‘t worth it. Looks like I will either have to sell the bracelet or look for a watch only 3590.xx :-/

The 3570.50 and 3894.50 use the same midcase.



I don't know if you can see the modifications I had to make.

I have read that the ears need to be in some cases gently filed, but do you think that will free up enough space for the endlinks to move up towards the case? Looking at my pictures it doesnt seem that it is possible, but since the lugs are curved slightly towards the tips, I wonder if this is even worth it. It seems that I would have to get the angle just right in order for them to sit properly, I don‘t know. I don‘t want to ruin the endlinks, either.

Well, where is the end-link hitting the case now? Relieve the end-link in that area. The end-link tab is too wide and too tall. Unless your midcase is different or they changed the end-link design, it is doable. It took me several hours over a couple nights with a diamond file.

I have looked at it further and have now changed my mind.

1) The holes line up on the endlinks fine, though they do sit a little high. Filing the ears would solve the problem of being able to get them mounted.
2) There would still be a gap on both sides, they will not sit snug on the case as they should. Something seems about the endlinks, but I am not sure what it is.

I don't know what to tell you. A 1479/812 100% fits the 80s and 90s Speedmaster. And vintage ones from the 60s and 70s. And the modern ones even. These cases are "identical" in this regard. It even fits my new-parts SM300. The end-links require filing, like the modern 1171/1 bracelet 633 end-link does since the end-links are made meaty so they can be modified to fit properly.


I'm not sure what you're seeing so I'm not sure if I can provide any additional advice. If it's a gap against the face of the end-link and the case, improper spring bars might cause that.

Thank you for your pictures and help. The endlinks in your pictures are sitting the way they should.

Do you think if I take everything to an official Omega retail store that they will be able to help me with this?

Would a different pair of end links work? I have a pair of 647s that I know will fit 80s and 90s Speedmasters. Happy to send them to you at no charge. If they work, buy them. If they don’t, send them back.

I really appreciate your willingness to help 😀, but I do not think that the 647 endlinks will work with the 1479 bracelet.

But thank you!

Thinking about this, it might just be something really simple such as the corners of the 812 endlinks I have are a little bit blunt and aren’t fitting in the space between the case and the lugs properly. We are talking about millimeters here. I have already driven the guy who sold them to me nuts, haha poor guy. But he really did his best to help!

Why not take the watch and bracelet to a watchmaker and see if they are able to shape and fit the end links properly?

I think an Omega Boutique could/would help. An AD might. A good watchmaker would.

Could you take a picture of the top of your end-links placed in the lugs?

Yes, I will do so this evening. The only problem is that I cannot mount them with springbars yet due to the endlinks sitting too high, but I can try my best to hold them on and snap a few photos.

Yeah, like you had them for the photos in the OP just from the top. Just trying to see what you're seeing.

I think this is probably my best bet, I spoke with one already and he works primarily on Rolex and wasn’t sure about working on these. I‘ve contacted since another buddy of mine who is a watch maker to see if they are willing/able to do it. Otherwise I am going to try my AD and see if they will help.

Update: I took everything to the AD today and had their watchmaker look at it and his opinion was that the endlinks wouldn’t fit without laser welding and modifying the links. Generally speaking, he questioned the authenticity of the endlinks and simply said that they wouldn’t be able to do anything in their store due to strict orders from Omega regarding modifications.

Looks like I will be parting with not only the bracelet, but also the watch, as I prefer the newest version with the better bracelet. As for the endlinks, I cannot sell them knowing what I already know, so lesson learned, I guess.

Thank you all for your help!

May I ask the source of the end-links, bracelet, and watch itself? I don't think the 1479 or 812 are really a target for counterfeiting. It's actually not a popular bracelet although it does have a loyal following for those that know. I guess anything is possible.
