Carrera calibre 15 I have owned this watch for several years about time i got more info on it. It has standard silver dial with black register with carrera in line at three, signed...McLaren world champions 1974... above the date. Was this a limited edition retailed model if so how many produced or was it made for Mclaren team only. The watch is all original in unmarked condition with original stainless Heuer mesh bracelet, look forward to any information about this one. Happy New Year Everyone.
