If there’s an incredible story to be told, Z Branch is where it happens.
Our special projects division takes remarkable stories, rare materials and unique opportunities and turns them into extraordinary mechanical watches. No formula. No rulebook. Just projects worth doing and watches worth making.
Longitude is where Zero West began.
Born from a fascination with cartography, navigation and John Harrison’s extraordinary pursuit of longitude through accurate timekeeping, the first Longitude watches defined both our name and our design language. Every model that follows carries that original DNA forward — making Longitude the heart of Zero West.
Airspeed brings together Zero West’s deep connection with aviation, aerospace engineering and the extraordinary people behind some of history’s greatest aircraft.
From visionary designers and remarkable machines to the pilots who flew them, every watch begins with a story worth telling. Airspeed captures those stories through mechanical watches designed to carry a genuine connection to aviation history.
HiOctane is where Zero West’s passion for motorsport takes mechanical form.
Inspired by racing cars, motorcycles, café racers and the people and machines that made their mark on history, every watch begins with a genuine connection to its story. From the TT58R and Stirling Moss to our Café Racer projects, HiOctane celebrates the engineering, character and raw mechanical spirit of speed.
