I want to know how to change the 12/24 hr format on armitron 40/8254. Not one video that I've watched had shown me this
Neat watch. I bought a solar watch, off ebay. Tired of buying batteries. It will do a double back flip. When the time changes, twice a year, for no reason, I take it to my guys. A favorite jewelry store, and ask for help. They fix it, for free, and try to show me how. Yours looks a lot like mine. FInd a jewelry store, and ask them to teach you how to fix it. Last Iime they fixed mine, I asked them to leave it on military time- thought I'd like to learn something new. That lasted a while. Then I hit something, and it's back on 'normal' time.
When I get back, I'll ask them to re-set it.
