The 'Silva' Wrist band 340 (sold in North America by Johnson Worldwide under the Silva label) is actually a variant of the Suunto Clipper wristband compass - which is an excellent design. Rotating dial, sapphire bearing, and surprisingly detailed degree markings for such a tiny compass. Great as backup to a larger protractor compass. These small liquid-filled compasses are prone to bubbles when they are exposed to high altitudes - don't put them in checked luggage on the airplane!
