Very good basic watch. Doesn't have many features but has enough and they are all useful. Only thing that lowers it is that it doesn't have smartwatch functions but for the price great watch

I am very pleased with this watch. It is very well made and quite striking with its red hands and indices. The service was also excellent with the 30% off and delivery within a few days just before Christmas

Great watch, much prefer RF time to Bluetooth seems more reliable, nice design and fit, you can’t set the date to UK format, dd/mm only does mm/dd
