Treatment of leather

Hello all

I have an IWC XVI from 2006 with a brown leather (alligator) strap. The
leather really seems to need some TLC and I wondered if you guys would have
any tips in regards to this i.e. what do you treat your leather straps with?..
if anything

Thanks

When my older straps get dry and drab, I give them a rub of Dubbin or Mink
Oil. Then shine up with a soft cloth.

First check on a small part, that the treatment does not remove any dye.
