Hey Guys-
I recently picked up a nice cheapie 40mm rolex explorer. What I am wondering is how hard it would be to upgrade this from a 21J Asian movement to an ETA highbeat so that the hand sweeps a little smoother. I am looking to try to mod this also with a gen crown and crystal but am unsure if it will take these mods. I am very new to modding and this would be my first project so any advice even as stupid as it may sound is appreciated.
Also, does anyone have experience trying to get the correct hand stack on a watch like this? I have heard that the Asian and ETA are simple movements which can cause the correct hand stack mod to be unreliable and break within a couple months. Is this a myth or do I truely need a gen movement for something like this?
Thanks in advance as I really hope to learn a bit more about this watch and modding in general!
