Duff the Gruff


The Watchful Ones are a rare collection of monster watches, designed for us by Onorio D'Epiro.

These fun and bizarre characters all work together as a unit, you can meet the other monsters here.

Each character in the collection is produced in a micro edition of just 30 watches, with each one individually numbered on the back of the case. Choose your favourite number from the dropdown menu above.

The story

Duff the Gruff comes from a long line of aristocrats and is The Honourable Percival’s brother. Although he may have regal green-blood coursing through his monster veins, he’s more of a down to earth kind of monster… quite literally! Duff enjoys nothing more than rolling around in the mud.

Despite his rough exterior, he’s actually a monster of some distinction: he works as a brain surgeon and was for a while ranked seventh in the world at Chess.

A unique way to read the time

This monster displays the time through his eyes: the left eye shows you the hours and the right eye shows the minutes.

To read the watch, look at the position of the white dot in each eye, this tells you where the eye is pointing.


Onorio D’Epiro is a designer and illustrator from Bedfordshire, England. As a child he developed a fascination for character design and special effects and mastered the video recorder at a precocious age in order to feed his passion for film.

He studied Model Design and Special Effects at the University of Hertfordshire and after graduating was drawn to the world of designer art toys. He began by creating one-off bespoke pieces and later developed a series of robot collectables known as “Justrobots”, which gained a dedicated following around the world.

His work has been exhibited widely including at The Pictoplasma Portrait Gallery in Berlin, The Victoria and Albert Museum in London, and the MARCO Museo de Arte, Contemporano in Mexico City.

He is currently working on developing some of his characters for a children’s television series. Check it out for yourself at: OnorioDepiro.com
