I hope you are right. This is a pic of the movement which is meant to be inside the watch - I have just run round to my watch servicer but he is shut already. I'll get him to check it over tomorrow.

In the mean time thanks for the info, its much appreciated.

: Tissot never used this movement, or any similar
: movement. My guess . . . just a Tissot crown
: on a Heuer chronograph / movement / etc.
