I learnt today that the parachrom material used in the hairspring of a lot of the new models is an alloy of Niobium and Zirconium. The tenuous connection (at leadt for me) to submarines being the Zirconioum is also the material used to clad the nuclear fuel in the reactors that power submarines. Something for the real nerds amongst us.
