The U-22 design is the result of a high profile military project where Bremont was commissioned to update the original U-2, using the extensive testing history behind it, but built and custom-tested to specific requirements. Taking its design cues from this squadron timepiece the U-22 features a newly developed bezel design together with a new barrel colour and date design for the range. True to its aviation roots, the updated date display was designed to reflect the view on an altimeter which balances the dial well. There is also a difference with the bi-directional rotating inner bezel, originally designed to measure 60 minutes, and altered in the U-22 to a compass quadrant of a pilot which is often useful in navigation weather mapping. The bronze barrel colour was specifically inspired by a number of military watches Bremont has produced in the past based on the anti-reflective coating used on their cockpit canopies.
