A good watch at a reasonable price. I've owned a couple of casio watches and this is the best as it ticks all the boxes for me - solar and radio controlled. It comes ready-to-use with the battery full-charged, although according to the manual, it will take around half day in full sunlight fully charge. G-shock makes it look tough and sporty. Water resistant upto 20 bar so can be used for snorkelling. The wave-ceptor/radio controlled means the watch displays accurate time and date in UK, North America, EU, China, Japan automatically. It gets the current time/date automatically in these regions or can be set manually in other countries. Recommended sports watch! The manual is easy to understand, but it's worth spending a few minutes reading it to familiarise yourself with the functions before pressing buttons.
