Bulova Accutron Day-Date 'Holographic'

Partially verified

This Bulova Accutron Day-Date 'Holographic' is a vintage wristwatch produced in 1976. The watch features an electronically powered tuning fork movement, specifically the Caliber 218, which operates at 360 hertz. Unlike traditional mechanical movements, this system does not utilize a balance wheel. The timepiece is housed in a case featuring architectural proportions and is paired with a two-tone bracelet. The dial is described as a 'Holographic' champagne display with applied indexes. The watch includes a day and date complication with a display window positioned at the 3 o'clock mark. The crown is located at the 4 o'clock position. The production year is attributed to 1976 based on the 'N6' caseback date code, with the 'N' designating the 1970s and the '6' identifying the specific year.

Object description

Movement and Performance

The watch is powered by the Bulova Accutron Caliber 218. This movement operates via an electronically powered tuning fork system, which vibrates at a frequency of 360 hertz. The mechanism replaces the traditional balance wheel found in mechanical watches, providing a continuous sweep motion for the hands.

Bulova stated the performance of this movement was within one minute per month. This battery-driven system represents a shift from mechanical timekeeping to electronic oscillation during the 1970s.

Evidence for this section

“Powered by the legendary Accutron Caliber 218”
“an electronically powered tuning fork vibrates at 360 hertz”
“accuracy that Bulova claimed was within one minute per month”

Case and Dial Design

The watch features a two-tone aesthetic, combining silver and gold tones on both the case and the bracelet. The case is described as having architectural, substantial, and grounded proportions. A champagne-colored 'Holographic' dial serves as the primary visual element.

The dial includes applied indexes and a day-date complication, with the aperture located at the 3 o'clock position. The crown is offset to the 4 o'clock position, a design choice intended to facilitate easier setting and wear compared to earlier Accutron models.

Evidence for this section

“A lovely 'Holographic' champagne dial with applique indexes”
“returned the crown to a more conventional position (often at 4 o’clock)”
“The case proportions feel architectural, grounded, and substantial”

Identification and Dating

The object is identified as a 1976 production based on the 'N6' code marked on the caseback. The alphanumeric coding system used by Bulova during this era utilized the letter to represent the decade, with 'N' corresponding to the 1970s.

The number following the letter identifies the specific year, meaning 'N6' confirms 1976. This model is noted as a successor to the 214 series, incorporating design refinements such as the repositioned crown.

Evidence for this section

““N6” caseback date code”
“The "N" signifies the 1970s decade, and the "6" indicates the specific year 1976”
“Introduced as the successor to the iconic 214”

Open research questions

Are there any additional hallmarks or engravings visible on the caseback that corroborate the 'N6' date code?
What is the specific material composition of the two-tone bracelet and case (e.g., gold-plated vs. solid gold)?
