Presented at the SIHH 2016, all three models in the Top Gun line from IWC had undergone a few modifications. The new IWC Pilot's Watch Mark XVIII Top Gun Miramar ref. IW324702 features all these modifications making it ultra appealing. First, instead of a soft strap, the watch now features an embossed calfskin strap that looks like a nylon fabric strap in military green.
