I am on my way back home from Goa at this moment.
A few weeks ago I asked Simona Di Stefano for advice who to keep my Bruno Allegrini Gamma Diver strap in the best possible condition when I use it for a swim:
After the swim rinse it off with fresh water
Let the strap dry on your wrist or at a non heated place where the leather can dry slowly
When dry, take the strap of the watch and apply a good amount of simple Nivea Cream on the strap on all sides
Let the Nivea Cream soak in the leather overnight
The next day wipe off the residual of the Nivea and you are good to go again.
Not sure if Instagram links work here, here is a clip of the my strap when wet:
And after applying Nivea, let it dry and rubbing off the residual:
Here the pics via Photo-bucket:
After drying, Nivea treatment:
The strap feels as soft as before!
