I attached a carabiner with a thermometer & compass to a CASIO GT-000. The crystal has no major scratches. The light also works. Battery replaced (May '23, made by Mitsubishi) Currently running. 200m water resistance Since it has a carabiner, you can attach it to a bag, pants, etc. The compass is reasonably accurate even when compared to an app. The thermometer is probably good enough as a guide (^_^;) #Click here for a list of hanging watches for sale Color: Black
