Does it have a step counter?

If you want a Casio watch with a step counter, you can look at the GBD100 or 800 series.

Does it really gain 2 seconds a week??? That would make this watch trash ....

Mine hasn't! Keeps accurate time.

Dose time update when you travel?

No. You have to physically update time or date if traveling across different time zones or cross international date line.

What actually is Tough Solar ?does Tough solar have a battery ?

Yes there is a battery that is rechargeable. It is recharged by the solar cell so you never have to replace it. As long as the watch sees some light once in a while it will keep running without having to worry about changing a battery

Exelente reloj

Muy buen diseño, si te gustan los productos tácticos te va a gustar, Olvídate de cargarlo ya que usa batería y es de carga solar , te muestra el nivel de carga en la pantalla, Termómetro , barimetro , altímetro y brújula todo esto sin depender de la electricidad de casa .. Recomendado 100%
