This one is just too strange not to tell you about. Zenith, makers of the fantastic El Primero chronograph, have teamed up with and a produced a limited edition watch for…..the Rolling Stones? Why? To be honest, it is pretty unclear. But, there will be 250 pieces made of this watch, which is the 42mm open heart El Primero Chronomaster, with the Stones’ tongue and lips logo at 6 o’clock.
