Hi Paul

I had to get the watch from the bank but here is a very rude mobile phone picture. It is cal. 12 with JRGK on the bridge.
JRGK = J.R. Gorgerat, Kelek SA according to Alex. Used in Kelek watches.

This tread talks about the same watches but no conclusions. http://chronocentric.com/forums/heuer/index.cgi?md=read;id=25163

: Great to have met you and the other as well. Sorry but I cannot
: help with the functionality of the watch but it is an
: interesting piece. In the 1970 catalogue the only automatic
: chronographs are the Heuer and Breitling Calibre 11's (Pages 25,
: 26 & 27) plus the Monaco on the inside cover. Your
: Chronosport is probably a later piece and it would be
: interesting to know what movement it has and the signature on
: the bridge. Can you post a picture?
