Tested and working, as you can see from the pictures. Light button doesn’t seem to work all the time. Shows the day of the week in letters which is cool(see 2nd last pic)
Press and hold the “lap time” button for a few seconds and the stop watch activates (see last pic). Reverse procedure to get back to time mode.
Time is set to the correct AEST for Melbourne Australia
Please look at my other auctions, for more vintage watches getting listed all the time
