When to use Seiko Astron 1969 Launch History Lookup
Use this tool to return Seiko's official prototype, launch, oscillator, accuracy, naming, or patent history for the 1969 Quartz Astron 35SQ.
Choose a supported lookup focus or prepare the measured values, documented evidence and caller-selected limits requested. Use the exact field names and confirm their units or date format.
How to use Seiko Astron 1969 Launch History Lookup and understand its results
- Choose a supported lookup focus or prepare the measured values, documented evidence and caller-selected limits requested. Use the exact field names and confirm their units or date format.
- 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 | Seiko Astron history focus | string; one of "prototype", "launch", "oscillator", "accuracy", "name", "patents" | Required |
Select one supported focus from the input table and run the lookup. Match the exact case-sensitive enum value; no trimming, synonyms or free-text search is applied. Return the selected focus and its stored history statement and historical/context label. keyDate, where present, can be a historical date, period or contextual label rather than a parseable date.
result=stored entry for exact selected focus Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| historyFocus | Seiko Astron history focus | string |
| keyDate | Key date or status | string |
| verifiedStatement | Verified Seiko Astron statement | string |
{
"input": {
"historyFocus": "launch"
},
"output": {
"historyFocus": "launch",
"keyDate": "25 December 1969",
"verifiedStatement": "Seiko states that it marketed the world's first quartz wristwatch, the Quartz Astron 35SQ, on 25 December 1969."
}
}Limitations and assumptions
No watch, caliber, manufacturing date or authenticity is identified. Modern Astron specifications are outside this table. This is a fixed local table; it does not fetch sources or update statements at runtime.
Numeric inputs 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 Spring Drive Glide Motion Principle Lookup: Return Seiko's explanation of Spring Drive energy, Tri-synchro regulator, glide motion, hybrid positioning, and technology-specific scope. For a complementary task, use Neo Vintage Year Boundary Screen: Screen a production year against explicit collector-supplied neo-vintage boundaries without claiming a universal 1980–2000 definition.
