Prometheus Design Werx

Built for Adventure

Our design process to create this modern classic drew inspiration from similar units used and worn by UDTs, Combat Swimmers, Explorers, and Adventurers from different era.

Reliable Legacy

The invention and introduction of the magnetic compass transformed the known world. Unreliant on batteries or circuit boards, a magnetic compass is the directional navigation tool in its most distilled and purest form.

Precision Made

The Expedition Watch Band Compass is made of aerospace grade, 6AL-4V titanium, highly resistant to corrosion and known for its excellent strength to weight ratio. The oil filled compass component is water resistant up to 100M/300'. The silicone carrier is treated with UV inhibitors to ensure that the colors don't fade and the material won't easily break down.

Compass Review

The compass is a great tool, built very well and hold true on its accuracy!! The only thing i would change about this compass is that I would only have the N arrow glow at night because it is a little hard to differentiate at night. The glow in the dark works amazing and lasts all night!
