    Brilliant fast delivery no faults with using them again. Absolutely love it only downside is I wish I had the black strap instead as the orange strap does stain with dirt easy but absolutely love it. Verified WatchO buyer (Purchase date: 22/12/2020)

    Best price, fast delivery, perfect

    Posted by Mr Mark Moyers on 19th Mar 2021

    Was a little apprehensive about ordering as I'd never heard of WatchO before. The price was by far the best I'd found online. With a discount code I saved 75 quid over other online retailers. Delivery was fast and I received the watch inside 5 days over new year. Love this watch, has everything I need and looks great. Verified WatchO buyer (Purchase date: 27/12/2020)

    Great service

    Posted by [Name Hidden] on 27th Feb 2021

    This was a Christmas present for my son. He loves it and uses it every day. He replaced a smart watch with this and says he prefers a real watch. Fast efficient service would definitely recommend to others and would use again myself.
