A very successful product. The small diameter of 72 mm makes the series ideal for my boat. There is a shortcoming in the watch. In the description there is no reference to the button cell to be used. You could also expect that at this price, the battery, which will only cost a few cents for the manufacturer, is included. Nevertheless, I can only recommend this product.
That was nothing, the clock shows a different time every day. Maybe the ones from the moon or Mars. But unsuitable here on earth -) It can happen that I send them back.
