This Franck Muller Sport Chronograph is an early limited edition, produced in a run of 50 pieces, and it catches the line in a more compact round format than most associate with the brand. Its manual-wind movement is a modified Lemania 1874, a base that gives the watch more mechanical interest than its straightforward name suggests and will matter to a collector looking past the dial. That original release status gives it a different place in the line as well, since later Sport chronographs returned in another form. In stainless steel, the case measures 37mm across and 12.4mm thick, a size that keeps the watch balanced and direct on the wrist. The black dial suits the watch's stripped-back character, letting the chronograph layout do the work without distraction. For a collector following Franck Muller's earlier sports watches, this is the version that shows the idea before it broadened into something less specific.
