Theres a wee sticky in the PAM section, there's a strap for every pocket (<$40 to >$400). IMHO recent oem straps are nothing special, far too conservative and look like they were chosen by an accountant (no offense to bean counters meant). The first thing I did when I finally got a Gen was change the strap. If you want a rep strap with a panerai buckle Davidsen does the only one spoken about with any fondness in these parts. Though doesn't look like a gen.
A bob honey tan faux gator looks quite like oemish considering it's $35
