I am about to build an SNZH57 Fifty-Five Fathoms mod using a Dagaz dial. I would however like to upgrade the movement to one that has hacking and manual winding. I recently upgraded my SKX007 by fitting an NH35 movement and using a SARB059 crown.
What movement can I use for the SNZH57? What do I do about the stem and crown? Any suggestions?
