Summit Quartz Calculator Watch

This is my Summit Calculator Watch which I have not worn since the summer of 1998, when I replaced the battery, the display did not come on, saw alot of green acid corrosion along the strips of the circuit board and part of the gold strip along the circuit board flaked away and needed tin foil to get the watch to work again. It then cycled up but could not remember the Dual Function when I saw a flashing D next to the time after the Stop Watch function on the watch itself. I could not remember how to set the Alarm, Date and Time but then figured it out after I stopped filming. First I showed the Chrono Stop Watch function which has Lap function, Calculator to show where the minus and E are on the display, Then Dual which I thought was the D for date or time was in settings mode but in the end it was Dual Time. to set the Alarm, Date and Time select Calculator mode and keep finger press down and when you see AL hyphen flashing slowly, it means you can change the time of alarm then date and then the time. The Beep does not work unless it works with only the alarm but could not find out as the watch died on me before I was able to do the next film on it. Will be taking it for a service in the next few weeks, look out for my third video on the Summit Calculator Watch sometime in the end of August/September time. enjoy and some info on the video for when the Dual mode is selected will be incorrect but only had so much time before the watch died on me once again and did 2 videos on it. A long detailed one which is this one and a 4 minute video giving a quick run though on including the correct info on the Dual Time Mode. enjoy and feel free to leave a comment.
This watch is from 1989 just so you know.
