Jubilee for a GMT

[athom]

Hi fellows, as you might already know I searching for a GMT 16700 and I'd assume I've found one. A circa 1993 with a oyster bracelet 78360/501B.
I'd like to buy a Jubilee who fits with the reference and the period. As far as I know, it should be a 62510. My questions are :

* What's the difference between 62510 and 62510H ?
* Which endlinks are the right for the 16700?


Many thanks guys !!!

You need 502 ends. You will also want the bracelet to be marked 50 on the last link before the end.

[juju38]

62510 don’t Existe
It’s 62510D for lady (13mm)
62510M medium (17mm)
62510H men (19-20mm)

Jubilee for gmt have 50 engraved on last link since 80’s begins
G or H on clasp code
Before it’s hard to see difference
Just jubilee for gmt accepting fat spring bar

For 16700 end link is 502b but 502 or 502t is ok
It’s the same

Thank you Julien, G or H on clasp should be 82/83, right ? Mine would be 1993, P, Q or R then? Do you mean I'll need other spring bars than for the 78360 ?
Also what's the difference betweenthe 502s end links? Some are SEL?

Merci !

Your Oyster spring bars are the same and will fit without any problem. 16700 from that era used 502B end links but 502 and the "no holes case" 502T end links will also work. As mentioned, make sure the last link on each section of the bracelet is stamped 50 on the right side of the link. The correct number of links is 22.

I wouldn't worry too much about the clasp code since the bracelet will not be original anyway.

You're right on the bracelets above, as you stated the 501b is the correct endlink.

I haven't ever seen a 62510H without the "H", so if there is one I'm sure we are about to learn this distinction as the experts chime in. They did make a "D" which indicated the ladies version...

Does anyone know what Jubilee should/could be worn on a 1665 Sea-Dweller?

Never tried on a 1665 but on a 5513. Same as above with 50 on the last link for 2mm bars. If I remember I got 502 end links to fit with some slight tweaking.

on the first jubile bracelet 62510H (clasp code A ) until those of the beginning of the year 80 (G or H) there is no visual difference between jubilee for DJ and for GMT , the engraving 50 appears after these years
the only way to know if it is suitable for a GMT is to see if it accepts the fat spring bar

i have 2 jubilée for fat spring bar
-1 with A clasp code and 550 end link( no 50 on last link)
i have try on 1655 , 1675 and 1680


-1 with E clasp code and 502 end link( no 50 on last link)
i have try on 16710 and 16700

E clasp code did not use 502 end links - correct ones are 550.

Also, there was a change to the 62510 bracelet on the later ones. The end rings changed from being round, to having a "bird beak" shape.

Below is a photo of the different end rings - although the photo depicts an Oyster bracelet, the same change in end rings can be found on the jubilee bracelets.

I know, when I bought the 62510H E, there were 550 that I sold because I had already, and I find 502 to go with my gmt 16700

normally it would have needed 502b but a friend had a 502 pair of them gave me

502 and 502b have the same shape so no problem

Conventional wisdom states that the 2mm springbar versions ALWAYS have '50' stamped on the last link, but it seems that it is not always the case as shown by juju38.
I've also seen others for sale.
Is it time to modify our thinking on this?

I won't be modifying mine. First time I've ever heard of this. Besides, I've seen D clasp codes before which is 1979 - which is prior to E (1980) codes. I'm not going to debate him on it, just seems that this would be a well known fact and it isn't. I share a different opinion than his. I've owned a few D and E 62510s with 50 link stamps and he claimed it started after that period. Additionally, I've talked to a couple other guys here that have not heard of this either.

I wouldn’t worry too much about it as long as it works. Personally I am not into later bracelets so if I am wrong; so be it. I prefer the older folded jubilee bands with 50 ends and if they don’t eat fat spring bars they can easily be adapted to do so.

I just tried to help. My experience is that they are indeed marked 50.

I tried on my 5513 and love the look. Very comfortable and actually I prefer the jubilee :). Try it if you can.



And also on my explorer II

Will the 502 end links also work on a 16710 and 116710? If so, that means yes for a lot of 5 and 6-digit pieces.

[michael067]

[YoureTerrific]

Tried 550 end links from Wholesaleoutlet. Didn't work on my 16570. Any suggestion on where to get 502s?

Thanks for the help!

[exador]

So...I've just obtained a 62510H for my GMT and it doesn't have the '50' stampings as per juju38's examples. The bracelet was sold to me by a gentlemen who has owned it from new - off his 1988 GMT 16750.

I've made comparison photos below with a 1981 62510H that I also own. The bracelets are for all intents and purposes identical except for the '50' stampings and fit the 2mm spring bars and 550 end links perfectly.

Therefore how do we explain this anomaly?

A. The bracelet is fake. No tell-tales that I can see and if someone was going to the trouble to produce a flawless repro, why would they omit the 50 stampings?

B. Someone changed the end loops on a Datejust bracelet. Next to impossible without specialised equipment - even Michael Young had to invent his own tool for the purpose. And there are no tool marks on the bracelet.

C. Rolex forgot to stamp the bracelets. Rolex sometimes goofs up (refer Cyclops with incorrect magnification). This is my bet.

Maybe seller opened the prongs on the end of the bracelet a tad to allow the 2mm spring bars? I do that on my unmarked jubilees. Just a thought.

No, the loops are a very specific shape with a design that stops them flipping upside down when the bracelet is removed. Enlarging them would destroy that shape.

And as I said, the seller received the bracelet from new on his 16750. I have no reason to disbelieve him.

[mattedialdoc]

Yes I am aware of the shape as I have several. It requires a fraction of a mm manual enlargement to allow a 2mm bar
