Review: Great Casio watch - I bought this watch for my husband to replace a similar watch of his which he lost. It’s a dark khaki colour, not too green, not too dark - it looks smart and goes with lots of things. He enjoys the Bluetooth connectivity function which alerts him to notifications coming through on his phone, and doesn’t find this as intrusive as some other brands. It’s a rugged watch which is built to last - his last Casio lasted him over 10 years and I expect this one will last him longer. It’s a dark watch face and he enjoys the analogue and digital clock, which can be illuminated. The light is not too bright but plenty to see in the dark. It’s a comfortable watch band which is durable. He also particularly enjoys the step counter function. Perfect watch if you don’t want something as advanced as a FitBit or a Garmin but need something which will last a long time.
Review: Excellent - Love this watch, had been looking for a watch that still kept track of my steps but wasn't a fully featured smart watch or fitness tracker. This is a true analogue watch and it keeps track of steps with the help of an accompanying app which works, it also alerts you to when you have messages on your phone. The watch is well built and feels sturdy on the wrist also the hands are easy to see but the lcd screen is difficult to make out underneath. It's also great this just runs on a normal watch battery so this doesn't need daily or weekly charging and should last at least a year before the battery needs replacing. Making it great value.
