The 262kHz movement represents a significant innovation in the realm of watches, developed by Bulova. This timepiece employs a specialized technology based on an exceptionally high frequency, specifically 262,144 hertz (Hz), equivalent to 262kHz. This frequency surpasses the standard quartz movements found in most watches. A higher frequency translates to greater accuracy and improved timekeeping.
Bulova watch with 262kHz movement
The 262kHz high-frequency movement represents an advancement of Bulova's groundbreaking tuning fork technology, originally introduced in the 1960s with the Accutron watch. The Accutron timepiece marked a revolutionary departure by employing a tuning fork as the timekeeping foundation, deviating from the conventional balance wheel used in mechanical watches.
The vibrations of the tuning fork in the Accutron watch were ultra-fast and provided unparalleled precision in time measurement for the time. The success of tuning fork technology laid the foundation for further innovation at Bulova.
These watches have a 262kHz movement >
This tuning fork technology gave timepieces a much higher frequency than the typical frequency used in quartz watches. The traditional quartz movement used in many watches typically operates at a frequency of 32.768 Hz. In comparison, the higher frequency of the most modern Bulova timepieces is 262kHz. This results in much greater accuracy and precision in timekeeping.

The elevated frequency enables a more uniform distribution of vibrations within the watch's crystal, leading to significantly enhanced stability in time measurement. This feature ensures that the watch is less susceptible to external factors like temperature fluctuations, maintaining a higher level of accuracy.
In its more recent models, Bulova has continued to refine the technology, enhancing the 262kHz high-frequency movement. This movement operates at an even higher frequency than the Accutron watch, specifically 262,144 Hz, yielding unparalleled precision in timekeeping.
Some high-end mechanical watches, such as Bulova's 262kHz timepieces, have a trailing seconds hand. In many mechanical watches, the second hand moves in a smooth, continuous motion instead of the typical incremental motion seen in many quartz watches, where the second hand makes discrete increments per second. It requires a more complex mechanism and precise tuning to achieve this smooth movement, which adds to the value and craftsmanship of the watch.
Bulova Precisionist.
One of the watches in which this 262kHz movement can be found is Bulova's Precisionist watches. These watches are known for their incredible precision, with an accuracy of several seconds per year. The use of this 262kHz movement is a continuation of Bulova's commitment to precision and innovation in watchmaking, building on the legacy of tuning fork technology that made the brand popular.
Bulova's 262kHz timepiece exemplifies the brand's ongoing efforts to improve the precision and quality of watches by developing innovative technologies.
