Convoy Calculator Watch

This is my Convoy Calculator Watch which I got from my parents for my 8th birthday and have just repaired it from the acid and corrosion which took a lot time and work. The functions this watch has is Calculator, Stop Watch and Dual Time. This video is me showing you all the functions the watch can do, and just to say, this Calculator watch is my stop favourite as I like when it shows all the days at the bottom and then a dot to represent which day it is etc. Enjoy the video
