I was considering taking up modding (not superlume though) but one watch I modded for a friend has gone missing in the post and it'll take 10-20 mod jobs to cover the loss, and if one of those goes missing, I'm in debt for no reason.
Mods are costly to do, high risk and you only end up getting in trouble if you don't have the skills of a The Zigmeister. Good luck to anyone who falls on this grenade for the good of the community.
For instance, how much would you be willing to pay for a relume, Cannon Pinion Fix or ETA datewheel swap?
