Yes, this is a fairly common and successful idea,
mrsullivan .
Ideally, still use a noob caseset for this, although my HF005 N series was not so bad, but even so, much inferior to him.
But collecting separately the hands, movt., Dial, case, caseback turned out to be too expensive for me, although: this is still probably one of the cheapest options for panerai, make the build as close to gen as possible without using gen (PANERAI) parts ...
Anyway, good luck with this project.
By the way, which series is your 005 HF?
