I had already downloaded the specific user manual, see Suff's post, on Saturday and had done all the tricks it suggested, to no avail, hence the thought of repair.
Cruiser, I use those cards for other things, torches etc, but the watch has a solar cell.
I am going to take it to bits and see what turns up.
