I've been recommended a modder by forum members who I'm going to send my 183 to for a lume job. I would also like to have cannon pinion fix whilst watch is with modder. Can someone tell me where to source this part? The handset is not good also. Can an upgrade be sourced for this? Also the screw down crown is not smooth can this be replaced? Your valuable help would be appreciated. I have already asked the modder but he told me to get opinions from forum members.
