Updated and
Upgraded

Our EWBCK 2.0 is newly redesigned for a smaller diameter and height, making this the lowest profile, titanium encased, dive rated, button compass available anywhere. A split back to fit over closed-loop style watch bands like variants of the Marine Nationale Paras.

Tooless
Change-Out

Another significant update is the ability to change out the compass element effortlessly and without any tools. Swap out button compasses as needed, or for the optional thermometer. 

Optional
Thermometer

Shown here with our optional thermometer. Easy to swap out with compass at will. No tools required.

Split
Back

The new split back design allows for the mounting of these to closed-loop type watch bands like the Marine Nationale Para variety. And of course these will slide over your standard NATO type bands as well. 

4 Silicone
Carriers Included

In addition to compatibility with a number of nylon-centric watch bands, our Expedition Watch Band Compass Kit 2.0 now also includes all 4 colors of silicone carriers. Change out the differently colored carriers to your liking or needs. The gray, OD green, and orange feature UV inhibitors to prevent fading and the 4th is glow-in-the-dark.

Built for
Adventure

The EWBCK 2.0 is your first and last piece of personal nav equipment. Compact and easily worn on NATO and MN Para type watch bands, or on your equipment with the included silicone carriers. Always know your heading, in any environment. Our design process to create this modern classic drew inspiration from similar compass units used and worn by UDTs, Combat Swimmers, Explorers, and Adventurers from different era. No batteries required, ever. 

Multiple
Carry Options

These can be girth hitched to your pack's webbing straps, D-rings, sternum straps and more. 

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.

Nice little gem!

I‘m really impressed by the craftsmanship of the Expedition Watch Band Compass Kit 2.0 as always with the EDC stuff from the Prometheus guys!
Perfectly matches my Victorinox I.N.O.X. Professional Diver in style and material. Great move to produce a Ti case that can be unscrewed to swap the compass e.g. for a new one or even for a thermometer.

Great job, PDW! As always!

Awesome

The compass kit/thermometer pairs great with my marathon pilots watch….the matte finish compares with the watch almost perfectly

2nd gen. compass

Better than the 1st gen. Smaller diameter and lower profile with a nice beveled corner. Doesn’t hang up on a coat sleeve like the 1st gen. had a tendency to do upon occasion. Be aware that even tightening it only finger tight, makes it very difficult too unscrew. A little anti seize on the threads will help tremendously. Very nice piece of kit.

Perfect piece of kit!

PDW knocked it out of the park again! The slimmer profile is a great improvement and the ability to install it on an elastic band (like the PDW offering) is a major plus!

Split Back Design

The new design of the compass works great on watch bands that are made of a thicker material. Being able to replace or use the other thermometer option is also a bonus. Thank you for the thoughtful design and upgrades.
