I swapped in a VR3185 the day my Arf arrived. Swap was straightforward with no issues and is runnnig strong and as said the datewheel is way better than arf.
My SH3186 was runnnig fine but wanted to swap anyway.
It also has a gen crystal and will get a gen insert next week!

Great! I've reserved a VR3185, hopefully I'll have it by the end of the month and I'll be able to swap them out. Did you have to use the movement tabs that came with the SH3186 or were you able to use the screws that came with the VR3185?
I'm going to have to buy a winder too. After this I'll be leaving that jumping hour hand alone as much as possible!
