About a year ago I bought one of them budget-looking Pathfinder watches from Casio, the SGW-1000 [3439]. Was a terrific watch. It let me know of changing weather conditions when in the mountains when the the peaks & trees blocked my view for clues. It even altered me once won a camping trip that thunderstorms were coming. Sure enough, 15 minutes later the rain came, then the lightning. I got packed in time. Watch did great when I was working in remote locations and with out riding the Rover. However... Woke up to a dead watch. Uses a CR-1616 battery. Went to Walmart, where I go for the 2nd PT job, got a new battery. Battery lasted maybe 5 minutes and was dead again. Went back to jewelry, put a new battery in myself. Die din 30 seconds. WTF Went home, read up on this battery change from a downloaded manual. Battery checked out good, worked in another device, put in watch, and the battery was literally drained under a minute. Tried a semi-used battery laying around in another watch. Didn't screw the cover on, only had it setting by its weight and the watch ran good. Screwed the watch back on and the battery drained. WTF Next day went to Home Depot, bough 2 new batteries. SOS. I really like this watch but I'm not going to buy another one for $97 if it's going to croak in a year's time. This is nonsense. Is there any hope of bringing this watch back to life?!? The compass & barometer comes is handy a lot. Used to have a smartphone that had these sensors in it before the phone started rejected the microSD card, now have nothing to alert me when I'm out riding the recumbent trike, and am planning on a mountain trail ride in a month.
