CASIO EFR 553D-1B

Combined sport men's watches are not only an indispensable assistant, but due to their appearance, they are also a luxury fashion accessory. The watch strap and case are made of stainless steel 316L, which is virtually indestructible. Mineral glass that covers the dial is very hard with a high silicon content, making it also scratch-resistant and abrasion resistant. The watch has an ionised circuit, a 30-minute stopwatch, a date indicator, a classic large dial and is water resistant to a depth of 100m.

Stainless steel

Stainless steel 316L is hard (does not bend), colour-stable and anti-allergic. It does not react with body fluids, so no metal components are released into the skin. The surface is completely resistant to oxidation and corrosion. The material is also resistant to sweat and a water splashes.

Water resistance

100M/10ATM refers to the degree of water resistance standardised by ISO 6425. ISO tests include alternating temperatures, depths, water and air pressure for varying periods of time at rest and handling the operating part of the watch.
