my claim to a CLOCK - Optics (a matter of taste) - Running time (no battery changes, always on vacation is the battery clock stand) - Gangenauigkeit - Fluoriszierendes Ziffenrblatt (holding all night) - Suitable swimming (100m), but not yet tried. everything fits.
Unfortunately not screw-down crown. Nachjustierbares bracelet with easy click, unfortunately, not.,
This still is the almost perfect clock, considering my claims to an almost perfect clock.
