Hey D I do have a history with shark straps...
When I was around 15 (about 16 years ago) there was a trend in greece and in my school for Camel watches.. I was in a school were most students were rich. The watches were nothing special but they were expensive for my family at the time.. SO my first ever replica was a Camel about 15 years ago with faux painted chrono.. very cheapo
To cut it short after a year my parents decided to buy me as a present a genuine Camel.. I was thrilled but the first thing I thought was to change the strap.. I have seen in the same store a nice Shark strap grey/black.. and the first thing I bought then with my own money was this shark strap to put to my gen Camel
So yes I am a calf guy myself (no exotics) but I have a soft spot for shark straps
