This is my first Casiotron. Casiotron’s were some of the first digital watches made by Casio this one dates from 1977. This was a good find, bought from a member in my Facebook group as a non running watch I found inside the usual battery corrosion which I successfully cleaned. When I fitted the battery it still refused so in desperation I left the battery in and put the watch in my pocket ( a trick I have learnt) sure enough a few hours later it was working.
This Casiotron 76CS-41 has some interesting features for its reduced size. firstly the seconds are represented by back markers that flash and stay lit per 10 seconds and fill across the screen. I have never seen this before and it is rather cool . Secondly it has a stopwatch or dual time function that is not obvious and I only found it through playing with the buttons. Like a Citizen I have (also on this page) this watch is either a dual time or a Stopwatch. It cannot be both.
Very nice bracelet sets it off. Classic LCD look but with a bit more quality than later models I feel.
