It leaked water within 3 months of purchase, without being used for swimming or any other related activity. The explanation from the store is that it is indeed waterproof, but steam enters from the hot shower.
The buckle on the strap is not durable. It broke in 4 months.

Nice watch, only flaw is that at night you can't see the time in the dark no matter how much you leave it in the sun during the day

Correct size for a large wrist, durable silicone strap, polycarbonate, lightweight case that may scratch but without being noticeable due to the texture. The stainless steel back cover with the embossed CAT logo is not screw-on but with a gasket and screws on the edges. The hands glow well at night with good duration (a proper exposure of 2-3 minutes to strong light allows reading the time throughout the night). Overall, quite readable even by... presbyopic individuals with the contrasting yellow dial/black hands. Citizen 2115 mechanism, which means reliability and not cheap Chinese mechanisms of the euro. Resistance to swimming (10 Atm) and mineral crystal that is hard to find at this price. Only Casio can match the specs, and even with a model with a metal case and 20 Atm resistance. But that is another evaluation...!
