With summer coming and surf season in full swing, I thought I’d take a closer look at the Casio EMA100-1AV Edifice watch with tide graph and moon-phase data. Casio is best known for their G-Shock line of beefy (and some would say ugly) plastic sports watches so this steel-cased model is a departure for the brand. Casio announced the watch in April and it is on sale now for $250.
