It has been a widely held belief that the rotating bezel seen throughout the horology found its origin story from the universally loved diving watch. However, this was not the case.

The rotating bezel by P.V.H Weems was invented with one goal in mind to aid pilots with a tool to navigate the open skies.

In the hands of a skilled user, the mechanical accuracy can be harnessed to pinpoint flight paths.

Accuracy in aviation was a must &ndash an error of 10 seconds or more could result in a navigation miscalculation of hundreds of miles over the course of a flight.

As a nod to the reliability expected from pilots, the rotating bezel is precise with a robust, ergonomic upgrade from the secondsetting dial.

In true UNDONE fashion, the Aero does not only encapsulate a homage to P.V.H.

Weems but also continues to pay tribute to the vintageinspired timepiece a watch that is true to its origins.

With an additional crown at 2 o'clock functioning as a bezel lock, often found on vintage aviation watches, it is designed to clamp down with just a twist of the crown.

The wider bezel allows for larger fonts and printing increasing legibility, improving easeofmanufacturing while also giving pilots a more accessible instrument to operate while wearing thick, leather flight gloves. Created for the aviator and vintage design enthusiast in you.

The Aero will be featuring two dial options: The Scientific and the Commando.

The Commando is a modernized interpretation of the original watch drawing design elements from field and aviation timepieces throughout the decades.

The speckled/ textured dial adorns highly legible Arabic hour markers indicating 12 hours in faux patina and 24 hours in red.

An orientation arrow can also be found at the 12position.

For ease of timekeeping, nononsense hands have been chosen with the minutes stretching to the very edge of the widened minute track.

The seconds are differentiated in a striking red which can be found at three different elements on the watch.

Helping hold this tool watch to your wrist is a pair of UNDONE's quickrelease Cordura straps chosen for their fray resistance and rugged durability.
