Yep - provided that:
We can have some decent lume on both the main and the chrono hands - one of the defining characteristics of both the EZM-1 original (it has great lume on both permanent and chrono hands), and of the PRS-17C (it doesn't!).
We can get some better-looking hour and minute hands than those on the PRS-17C.
BTW - could you fit a 251.262 quartz movement into the Sinn EZM-3 case? There would need to be some holes for the chrono pushers, but otherwise that would be a great case and dial for a similar project.
