I got this
Surftimer as a gift from a friend in the UK. I don't know much about
this model or this series of Casio watches. There are several of these
type models, like my DW-400
Tachymeter. All I know is I like the design with big push
buttons. They look a bit like the vintage G-Shock models without the
bezel. Note that these models are also 200m Water resist!
