Whether you’re conquering a boardroom, a mountain, or a sandy beach, your Tsar Bomba can evolve with you to match the look you want to show the world.

Elevated Performance

The Reactor Series is crafted from durable and rugged 316L stainless steel that is resistant to scratches and corrosion. It also boasts a water resistance rating of 100 meters meaning you can swim, shower, and dance in the rain worry-free. Additional features include anti-reflective coatings on the sapphire crystal for visibility in all conditions and a Quick Release FKM rubber strap built to withstand all weather conditions as well as sweat and bacteria.

Designed for Performance and Durability

The dial of the Reactor Series is protected by an ultra-hard sapphire crystal to resist scratches and marks from daily wear. Underneath, the dial glows with SuperLuminova allowing you to read your watch even in pitch-black conditions.

Precision Timekeeping

Featuring a fully automatic movement beating at 21600 vibrations per hour, the Reactor Series strikes the perfect balance of accuracy and durability.

Embrace the Unconventional

The core of the Reactor Series is a dial that boldly challenges your expectations in a timepiece.
