A very early quartz after the F300.

A big and great watch and perfect running with a sliding second hand.
Some scratches on the case and strap.
Signed both crowns and the upper crown is for the inside ring
All working perfect.
Original strap and signed buckle full lenght.
Tissot signed movement so a complete original T12 Tissot !
A very hard to picture watch with the inside reflection dial and the scratch free bolded glass.
