Accutron Spaceview 314 26A211 – The Return of the Legendary Tuning Fork

The Accutron Spaceview 314 26A211 marks the return of one of the most important technological breakthroughs in watchmaking history. Inspired by the legendary Accutron Spaceview models of the 1960s, this modern reinterpretation revives the iconic tuning fork technology that once revolutionized precision timekeeping.

The watch features a 39 mm polished 904L stainless steel case with straight lugs and a crown positioned at 4 o’clock, paired with a black padded Italian calf leather strap with double-press foldover clasp for a refined and comfortable presence on the wrist. 

A domed sapphire crystal provides an unobstructed view of the open dial, which showcases a silver-tone chapter ring with LumiNova hour markers and a matching handset. The dial design allows the intricate tuning-fork movement architecture to be admired while maintaining excellent legibility. 

The result is a timepiece that merges historical significance with contemporary craftsmanship — an icon of electronic watchmaking reborn for modern collectors.

The Y230 Tuning Fork Movement

At the heart of the Spaceview 314 is the Accutron Caliber Y230, a modern evolution of the revolutionary tuning fork movement that made Accutron famous.

Unlike conventional mechanical watches that rely on a balance wheel, the Y230 movement uses a vibrating tuning fork operating at 360 Hz. This electrical signal drives the timekeeping mechanism and produces the characteristic smooth sweep of the seconds hand along with the distinctive F-sharp hum that collectors associate with historic Accutron watches. 

Each movement is hand-assembled and incorporates modern materials such as silicium and Elinvar to improve efficiency, stability and durability compared to earlier generations of tuning-fork movements. 

The result is a rare fusion of vintage electronic watchmaking with modern precision engineering.
