Bulova Accutron Tuning Fork History Lookup

Return Bulova or Royal Museums Greenwich facts about the 1960 Accutron launch, 360 Hz tuning fork, accuracy, distinction, and Spaceview dial.

Description

The original Accutron used an electronically maintained tuning fork rather than a balance oscillator.

The original Accutron used an electronically maintained tuning fork rather than a balance oscillator. That distinction matters when comparing mechanical and quartz histories.^[1]

When to use Bulova Accutron Tuning Fork History Lookup

Use this tool to return Bulova or Royal Museums Greenwich facts about the 1960 Accutron launch, 360 Hz tuning fork, accuracy, distinction, and Spaceview dial.

Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.

How to use Bulova Accutron Tuning Fork History Lookup and understand its results

Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.
Enter historyFocus using the field table and calculation rules, then run the tool.
Read historyFocus, keyDate, verifiedStatement. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
historyFocus	Bulova Accutron history focus	string; one of "launch", "oscillator", "accuracy", "distinction", "spaceView"	Required

Select an exact supported historyFocus value from the field table and run the lookup. The implementation selects a fixed local table entry and returns the fields shown below. Matching is case-sensitive, with no trimming, synonyms or free-text search. Any keyDate output can be a date, period or context label.

result=stored entry for selected focus

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
historyFocus	Bulova Accutron history focus	string
keyDate	Key date or status	string
verifiedStatement	Verified Accutron statement	string

  "input": {
    "historyFocus": "oscillator"
  },
  "output": {
    "historyFocus": "oscillator",
    "keyDate": "original movement",
    "verifiedStatement": "Royal Museums Greenwich describes a tiny tuning fork vibrating 360 times per second and maintained by a transistorized circuit and battery."

Limitations and assumptions

No watch, movement, launch claim or present accuracy is independently verified at runtime. No sources are fetched or statements updated at runtime.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Beta 21 Swiss Quartz History Lookup: Return the official consortium, prototype, industrial-launch, production-volume, or Swiss-response history of the Beta 21 quartz caliber. For a complementary task, use Four Five Hertz High Beat Comparison Lookup: Return explicit 4 Hz and 5 Hz frequencies plus Grand Seiko's power-reserve, longevity, accuracy, and high-beat terminology cautions.
