I have an Eterna Kontiki Super 1973 re issue (supplied on a mesh), however to fit my slender wrists I would have to cut the mesh & I'm not sure I want to do that at the moment. This got me thinking about alternative straps & got me wondering as to what would be 'period correct-authentic' to keep it with a true 1970's vibe. Obviously I could just replace the Eterna mesh with a mesh that fits but what would be other 'authentic' options.

Beads of Rice
Jubilee
Oyster
Leather
Nato
Rubber

I am leaning towards a Geckota beads of rice bracelet from WatchGecko but would this be period enough, what are your thoughts.
