5 minutes is a ____ time

We made Durr to explore how we perceive 5 minutes in different situations. By markedly shivering every 5 minutes, it creates a haptic rhythm to make us notice the changing tempo of time.

Wait what

Time perception is our subjective understanding of how fast time passes. Our ability to accurately estimate durations depend on a range of factors. With Durr you become aware of how your brain alters the length of a bus ride, how fast you finish a beer, how time flies by when you enjoy yourself, and drags along when you wait in line at the post office.

Alpha colors

This is an internal experiment, but we wonder if more people are interested. Are you? We have made 50 of these, as a limited alpha run. It comes numbered in 5 different colors (10 of each), with a replaceable battery that lasts up to two months. The diameter is 39mm, height 9.5mm. See the color range below.

Made in Oslo

The chassis and fastening mechanism of Durr are sintered in polyamide and hand-dyed by us. The strap is laser-cut Norwegian vegetanned leather, and we program and hand-solder the electronics with RoHS-compliant (lead-free) components on ENIG-plated circuit boards. We're writing about how we make them on our blog.


No, you can't adjust the time between vibrations. It's ON/OFF only. Trust us, we tried everything between 2 and 15 minutes, it was either too short or too long. About 5 minutes is perfect for its purpose. Oh, and no, it's not waterproof, so don't shower with it.
