Vintage Speedmaster on Bracelet - Number 6 End Links - Genuine?

looking for a bit of advice here from the resident experts. I have been offered a 7912 bracelet complete with Number 6 end links, which I am seriously considering.

However, looking at the images the two end links appear different. The number 6 is stamped in a slightly different spot and one end link appears to have two slots for accessing the spring bar and the other only has one.

In my relatively limited experience end links tend to be the same. I am aware that a guy on e-bay sells modern reproductions, but deliberately makes his look distinguishable from the originals so that the cannot be passed off etc.

The watch they came from and the bracelet all look good to me, but it just seemed a little odd that the ends were not identical.

Any advice would be much appreciated.

Thanks,
Ken

One is a double notch and the other a single. They are both original 6s but one is earlier than the other.

Modern repro 6s are completely smooth on the back.

Thanks that is reassuring, would it make any difference to the desirability or value.

Single notch ones are more valuable as they are only correct for early speed/seamasters... on the speedmaster side, they would only work for up to a 2998-4 at the very outside (and even that may be questionable).

I think they came off a 2998-3. Key question, would they fit to a 105.003-64 which is what I have?

They will fit, but they will be technically incorrectly... fwiw..

Thanks. I assume that the 7912 is the correct bracelet for a 105.003, but if these are technically incorrect - what would be the correct end links?

Just checked the table, looks like Jan 1966 is 1035.

yes, double notch #6's would be correct for a 105.003.

given the date ('66), I would personally prefer 1035/506, but then, what's the difference (other than price and availability)? 😉

Very glad I asked, all info gratefully received. Any advice for the seller with an early bracelet and two odd links.

well, the mstanga table says that 7912/6 is good for 105.003-63,64,65, and -65's were made as late as 1969, so it's possible a 105.003-64 made/delivered in '66 came with a 7912/6... If the price is OK, it will look the part, but -- for me -- the single notch #6 is out of place. Would it bother me? No (well, yes). 😁

+1 for the double notch end link for your 64. I'd also consider the year stamp on the inside of the clasp of the 7912 and ideally I would like 65 or 66 to go along with the deliver date of 66.

If it helps, my 105.003 is completely original which has no 6 end pieces with 1039 bracelet. Mine is dated from August 1967 with 24951*** movement number.

Another member here called southernscot has exactly the same setup with his 105.003, his movement number is within 9 digits of mine.

So yes you have the correct end pieces although I've no idea if those ones are reproductions or not.

Thanks guys. I think looking at the table the 1035/506 configuaration seems to be the correct set up for a 22,82m serial number from Jan 1966.

C'mon guys are we really getting to the point where we're debating whether or not a nr.6 endlink is correct or not for a certain reference based on it having a single or double notch!

😵‍💫 🙄 🤪

The suggestion seems to be that the single notch number 6 ran until the 2998-4 and was replaced by the double notch (?) which presumably ran until the end of production of the 7912 - is that correct and was there any cross over when both links were used at the same time. Just trying to establish the timelines here.

Given that people think both Number 6 links are genuine, is it really an issue that they are different?

It depends who you talk to. I wouldn't give a shit, but maybe it's just me.
I would love to get a bracelet for my 105.003 but when I think that I could get a nice 145022-76 for the same price, I think I'll never own one 😀
