It is just interesting to see the “Bâle 96 Prototype” posted by Amanico about a month back (sorry couldn’t figure out how to link to that post) has 37 jewels 🤔

Not every day you see two Reverso Chronographe Rétrograde side by side. Please say hi to no. 208 and no. 413. One with 37 jewels and the other with 36. Clua ...  

Why is there a difference in jewels number between the two?

This chrono is raising my interest in the recently introduced steel model…which is worrisome for my wallet. But you make it look so good.👌🏽

That is a little bizarre!?

Maybe movement update during model run? Odd because this was the only ref using this I'd believe (and the gransport?)? All I know, it's beautiful!

I haven’t found the explanation yet…

…and the other owner was also aware of this but did also not have the explantion. Maybe there”s a WIS in here who knows? And as for the tribute, I honestly prefer this (original) version due to the better size (for me) and the ‘Arret/Marche’ indicator on ...

Amazing nearly identical twins!

Did they win or lose a jewel with time? Best, E.

Yep.

Input from La Grande Maison on this mystery

 
 By: cfn : December 25th, 2023-15:36
Yesterday, I wrote a contact at JLC to hear whether he knew of the back story or had an explanation. This is a person very well placed for this kind of question. And please note that he not only took the time to reply, he did it on Christmas Eve. Anyway, ...  

Thanks for this answer!

Awesome! Thanks for the amazing answer!

The mystery is solved!

Indeed!

But not everyone has the same access as you do! So you're definitely special and getting the full JLC experience!

+1 alas.

Arrêt Arrêt Arrêt! There are two different jewel counts?

 
 By: patrick_y : December 21st, 2023-19:17
That would technically mean these two watches aren't exactly the same caliber!!! I never knew this detail! Wow! Thanks for sharing! And what a pleasure for the eyes to see two very rare twins together! Is the other owner also here on WatchProSite? If not,... 

I hope he is!

Great a trio would even be greater.

the grand sport chrono cal 859 has 38 jewel from 1998

 
 By: golden hands : December 21st, 2023-19:47
the original 1996 cal 829 has 36j designed by manuel guerin the upgrade cal 829 with 37j 1996-7 so you can see the progressive jewel count for this fine chronograph as for where the jewels were added-??? need the technical drawings for that.

Wow. Trust this site to find the answers!

 
 By: cfn : December 21st, 2023-20:28
Funny thing here is that it”s no 413 that has the 36 jewels while no. 208 is the one with 37. But I guess they could have been assembled/cased/numbered “out of order”

Here it is.

Did some googling. See here....apparently 35, 36 and 37 versions

 
 By: cfn : December 22nd, 2023-11:46
A good way down in this article you'll find “(versions with 36 jewels or even 35 jewels are also known to exist. It could be that one of the jewels of the earlier 829 was merely decorative and was subsequently removed),” monochrome-watches.com

Wahooo amazing!

Exactly! Next challenge is getting 3 in the same room

We have a friend in common who also has one. We need to meet with him in 2024.

That would be fantastic !
