I put my PAM 111 on a dark brown Serge strap I received from the generosity of my friend Chris M. (aka Speedmaster). Thanks Chris! What a difference a strap makes. It has breathed new life into the 111 as I was getting bored. Nice and thick, but not ridiculously so. The buckle is the curved type "Pre-V" style bottle-cap. It's a brand new strap, but it feels broken-in. It's very comfortable and has a vintage aura to it.
Serge straps are some of the best value per buck aftermarket Panerai straps out there. Check them out!
