My latest watch is this Timex. It is very accurate and I like the style. Also its my first working Dynabeat! I have had many but never got them to work. Been using it for a week now and its exactly 30 seconds slow. Not bad for an early electric watch? 36mm wide not counting the crown makes it a fairly modern size. Anyone know anything about these? What is the difference between the Dynabeat and the ones that only say electric?
