Zitto says it has sold over one million watches worldwide over the past three years.
The brand targets a young sporty market – people who want something a little different on their wrists, and are not afraid to wear the soft-touch silicon watches that come in a range of 26 vivid colours.
Zitto watches, which connect to a smartphone app, have LED screens that show the time and date, depending on how many times you tap the screen.
They are waterproof to 100 meters, making them a great holiday watch.
The brand has been a sensation in Ireland, where it has dozens of retailers.
Mainland Britain is about to be blitzed, with the aim of dramatically increasing the number of retailers for the brand.
The watches sell for under £30 each.
