I dont have a picture, but I use a watch on mine too. I have a cross bar pad on the handlebars and wrap a cheap watch around it. Gravity tends to twist it so the watch ends up on the underside, but a quick twist of the pad and its visable.
I bought one several years ago to use on a ZRX I had at the time. Bought the thermometer too. They both died in less than 2 years. Watch was too small to read at a glance anyway for my eyes. Would not buy again.I had the small Aerostich clock mounted on the bar of a Ural side hack. It lasted almost 2 yrs. I called Aerostich as I thought the battery probably should have lasted longer. ( I wasn’t complaining as much as I wanted to know if this is what I should expect). They sent me a new watch and said it should last up to (5) yrs . Great customer service there. Anyway even thought it was small it was very handy-easy to read and waterproof. Probably what I’ll buy again.
