Just received the new bespoke matte black ostrich leg strap for X350 XJR's Seamaster he graciously sold me. Fresh from a service a couple of weeks ago too, keeping great time and amplitude on that mint cal 500. Shameless plug, if you're in the market for a full custom exotic strap, Aaron's your guy: http://www.aaronbespoke.com/ This combination is my new favorite thing, a bit of a distraction on the wrist when stopped at traffic lights.
