SwatchPAY!
This timepiece is powered by highly reliable Swiss-made quartz mechanisms. It is water resistant up to 30 metres, making it suitable for light splashes. The watch also offers SwatchPay which allows you to connect your debit/credit card with the watch so that you can simply tap your watch on a card reader to make a payment, just as you would with contactless or apple pay!

A very cheap watch which could not be more classically styled. This makes the inclusion of contactless payments in such an invisible way even more impressive.
