Good shows precise, resistant wristband, I am a mechanic and the door to work (I for several years), watch box a little thick. Almost 3 years of independence, I just replace the batteries (SR927SW) I used to wake me for !!!. It is very powerful sound level (Attention there are two batteries and one must be a little handy). Otherwise same criticisms for readability white needles on white top ... Otherwise not good as somewhat resistant watch all Casio. If you can have it like me promo (35 euros in April 2009 ....)
