The finest materials. No compromises.

Made with premium genuine leather and crafted from a block of solid black walnut. Each Tempest Deluxe is unique, with variations in both leathers and woods. Natural materials patina beautifully with use. It's internally sound dampened and weighted with heavy gauge steel, fully lined with non-slip silicone. As refined as it gets and worthy of its place alongside any of your most valuable sets.

Our gold standard is all black.

Bundled with the same software and made with the same smooth rocker mechanism as the Deluxe edition, Tempest Standard features ultra-smooth synthetic (vegan) leather on a durable polycarbonate base. Finished in contrasting matte and high gloss piano black. Full-sized non-slip silicone pad. Weighted with heavy-gauge steel. Tempest is refined and battle ready. It's your move.

“Amazing and Unusual. The analog is as perfect as the digital.” -WGM Dina Belenkaya

“It’s odd that game clocks haven’t evolved. In some ways, they’ve gotten worse.”



I'm a big fan. it's really slick, and so easy to use. I really think it will revolutionize chess on the go.

It's super easy to set, even in bullet games it doesn't move around. It's a really good playing experience.

In 30+ years of competition, I've tried every clock there is. Tempest is the simplest and sleekest yet.
