In the early/mid 80sa friend of my fathers had a full faced digital watch that had a rotating bezel thst changed the mode on the watch(stopwatch, dual time, alarm etc). As an 8yo (thereabouts) I was completely besotted. My life long fetish for watches started right there and then.
It could have been a Seiko, Citizen or even Casio. I have know idea. I remember it being rated to 200m water resistance. I'd love to get my hands on one. I had a cheap Kmart version of it that fell apart I begged my mum to buy me for my birthday.
