Hi
I bought this mildly interesting seiko quartz about a week or so ago, It's not the sort of thing that I go for as a rule, it's a little bit dressy for me but it was a movement I'd not owned before. The watch in question is a 4826-9009 so when it arrived I had the back straight off to reveal a rather nicely made 7 jewel movement, I knew it was not going to be easy to find the so-called silver oxide with special treatment battery but I had already found some info to say you could just use a normal battery and not use the solar charging bit.
So in goes the fresh cell and......nothing, dead as a dodo. Ok I thought , that's dissapointing but not terminal so first port of call was my quartz timing machine which showed no pulse at all, bugger I thought but out came the multimeter to check the coil, which passed with flying colours so on to the circuit, once it was removed and the top cover was taken off I could see that the circuit was mint, not a speck of anything on it but I cleaned it anyway, So all back together and............nothing, still completely dead, just to be sure I tested the voltage of the new battery which was fine and dandy putting out 1.57 volts, again I muttered bugger and went through the whole dismantle and clean again and again and still nothing so I gave up.
fast forward a few days and I thought just one more go, so off came the circuit again for another little clean and then started to reassemble, When I reached the final screw which could be a bit fiddly as it also held the negative terminal for the battery (get it wrong and the springy brass would launch the screw) I tweeked the terminal with my tweezers to negate the see-saw effect and finaly realised what may be the problem, the terminal was protruding a fraction from it's groove in the wall of the battery holder which of course meant it was touching both negative and positive on the battery Doh!!!
So now I have a working watch, Hurrah!! Keeps great time too so far and the moral of this story is that even after tinkering for years I'm still an idiot
