It's time for the old Casio watches again with another of the original Casiotron range.
This model is one of the smaller case designs for the Casiotron watches, so I guess it was a unisex or ladies model.
The model is a 76CGS-41, which seems to have been produced in 1976 (based on information on the casiodigitalwatches site for other 76CGS models, but the -41 isn't mentioned online anywhere). It has a 3 1/2 digit LCD with a star pm marker in the top right (at the Saturday marker). Across the top is a set of bars for day marking when in date display, but these also act as a seconds display, flashing during a 10 second period before the next one starts.
This watch is a gold model, and has a matching gold strap (with part number B-159L).
