The Casio LCW-M100DSE-2AER men's watch works on solar energy. On the watch you also read off the date next to the time. You simply set an alarm or timer on the Casio, so you never forget an important event. The watch case and strap are made of durable and solid stainless steel. Do you also want to know what time it is in the dark? Thanks to the LED lighting in the display, this is no problem. The watch is 5 bar waterproof. This means you also wear the Casio in the shower.
