The Cheapo strap on is the way to go, but some people suffer from FARKELITIS. DonG
If it's the Marlin you have, I have the tool to unscrew the back. I can mail it to you. I lost my clock, bounced outa the holder. I use old wristwatches and Velcro now, like other cheap guys!
The back plate has 6 notches on it and all the seams are so flush that's why I figure it screws on. Don't remember the brand but it's really nice and only cost me $17 new, so I got 2 of them. I could take it to a watch dealer but if I could get the tool that would be nice too.
One can buy a clock and thermometer that mount to the handlebars on Amazon for around the same cost as a "strap on" watch. https://www.amazon.com/WXLAA-Motorcycle-Handlebar-Thermometer-Waterproof/dp/B01M4MYBFQ/ref=sr_1_11?ie=UTF8&qid=1490725270&sr=8-11&keywords=motorcycle+clock+and+thermometer
Something to do while doing those looong straights out West.
Just retire------ then u won't need a watch
Here's my report. I received the Amazon $7 tool, which turns out to be wobbly junk, unable to remove the backs on my two clocks. I also tried the duct tape trick, but no success. I'll take the one with the bad battery to a watch stand, and have them try it.As I mentioned, I have two clocks, both seemingly the same model. Namely, this model: https://www.amazon.com/Universal-Waterproof-Motorcycle-Handlebar-Harley/dp/B019WERJJY/ref=sr_1_1?s=instant-video&ie=UTF8&qid=1491099619&sr=8-1&keywords=motorcycle+clock+black.The slots on the back of one of mine are shallow and difficult to engage with the removal tool. The slots on the other one are even worse -- much shallower. It's the only part of the clocks that seems poorly machined.
