Cuidado con sumergirlo que en la faq del manual del propio reloj dice esto:
4. Is my Chronos waterproof?
Yes, it is 30m waterproof. This indicates that it resists splashes and rain. However, it cannot be used
while taking a shower, swimming, diving, surfing, snorkeling or any other water sports. Set the watch
before exposing it to excessive water. Pressing the buttons in water or heavy rainstorms may cause
water to enter the watch.
Resumen: resiste salpicaduras y lluvia pero no se debe usar en la ducha, nadando, buceando, etc. Vamos, lo que han dicho por ahi
