i bought a tag f1 when i was a lad that lasted very well, as i too used to munch through watches regularly, but got hacked off with either sending it off to tag for a new battery and pressure test, or finally going the cheap route, then having it leak. replaced it with another of the same ( which had more than doubled in price over the intervening 8 years! ), but that never really seemed as good as the old one, and i gave up on that after the second or third battery.
now run the waveceptor/tough solar g-shock. ace. truly fit and forget. accurate. no battery or other servicing required. when it does eventually get broken, if someone drives a tank over it or something, i’ll go straight out and buy another.
