Maybe this isn't directly related to timekeeping, but specifically from Hublot, Urwerk and Richard Mille - seems like every few months there's a new gold, or crystal, or ionized titanium or whatever.
In addition there are struts and cushions and isolating elements between case and movement.
In RM's case they claim it helps the watch survive tennis, yachting, etc.
I'll keep thinking...
How about the sapphire link chain in the Logical One?
