How do you know when the battery is low or flat

DO NOT BUY A TISSOT! I purchased the watch on a Royal Caribbean cruise ship out of Venice in July of 2007. I LOVED the watch, and am a big outdoorsman that used the compass and altimeter, barometer—everything a lot hunting bighorn sheep in the Rocky Mountains. I literally thought I could be a commercial for TISSOT TOUCH. Last summer the watch quit working, and then started again, it worked on and off for a few months intermittently stopping—I assumed it was the battery and when it finally stopped for good I took it to my jeweler to have the battery replaced. He could not open it, which I discovered was a good thing because the warranty would have been void. I then contacted TISSOT through the website, and within a few days Veronica responded Friday, November 7, 2008, 9:14 AM. Since then I have been in touch with Time Tech, a referred watchsmith on your list, I sent them the watch (WITH a battery, since I expected that was the issue) only to discover after several weeks of persistence, that they do not work on the TOUCH and sent it away. It then took me quite some time to receive any further information as to where the watch went, who has it, what they are doing with it, when I will get it back. Of course, all this time, I was still thinking I had an $800 watch. I finally receive, after persistence once again, information that they sent it back to “the factory” and I cannot call them because Time Tech sent it to them and is the customer, not me, so they will not talk to me. OK, fair enough, after all I am getting my watch fixed for free, it is a warranty issue obviously—what happens next? I receive an estimate for $400, $245 minimum from TIME TECH. Where is the estimate from “the factory” or is the watch being repaired under warranty and Time Tech is charging me $245.00 to coordinate it? Also, why could I not send it to the factory in the first place? At this point I am thinking of tossing the watch and regretting the whole purchase—I can’t even sell it, it doesn’t work, and functional used one can be purchased for $290.00 on ebay—that is what I am being charged just to get mine back. I have been told that I need to get the battery replaced about 1/year (?) That seems like a pretty big hassle for an $800 watch. Did I make a mistake in buying TISSOT? As cool as the watch is and as much as I loved it for one year, that is a pretty expensive short term investment. DO NOT BUY A TISSOT!
