Hello friends,

Been reading some of the RWI technical posts on rep movements.
I still don't know how to answer this...please help me with my latest project, I need expert help.


I want to buy this 42mm cartier calibre rep with A23J movement: (The best version of this rep comes from a factory that decided to offer this only with A23J and that version is THE BEST, as opposed to the worse rep made from a factory that made their version with only ETA movement)

I want to exchange the "stock" hands for BLUE hands, to fit one gen model exactly like this. I will try to put in the blue hands that come in this one, obviously another model but also 42mm so same hand length, and with movement A21J instead of A23J:

Its the only model I found with blue hands , 42mm and that has a "similar" movement! Do you think the hands would fit without any mods? some say the A21J is identical to A23J, are the cannon pinions the same?


There are also rep cartier 42mm blue hands on the following movements:
Swiss Ronda 6203.B Quartz movement and ETA2824.. Would the hands that come with any of this the A23J?

MY SECOND OPTION/IDEA:
Get a cartier rep 42mm with the BEST blue hands I could find -A 42mm ballon bleu from V6F- that comes with an ETA2824:

I would then swap the whole movement complete with hands to the receiving rep (Cartier Diver), but I don't know if the dial/crown etc will fit. How is it best to proceed here?


Thank you all of you for the help!

I bought a watch with a "23J" movement in it and it turned out it was just a 2813......one of our classic 21J s in reality...so yeah the hands should swap without a problem
