ISO 6425 Diving Time Indicator Lookup

Return the current ISO 6425 scope, one-minute resolution, five-minute marking, handling-protection, or unidirectional-bezel design context.

Description

A diving-time indicator measures elapsed time under a defined watch standard.

A diving-time indicator measures elapsed time under a defined watch standard. Visible bezel features alone cannot establish compliance.^[1]

Return the current ISO 6425 scope, one-minute resolution, five-minute marking, handling-protection, or unidirectional-bezel design context.

When to use ISO 6425 Diving Time Indicator Lookup

Use this tool to return the current ISO 6425 scope, one-minute resolution, five-minute marking, handling-protection, or unidirectional-bezel design context.

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 ISO 6425 Diving Time Indicator 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 requirementFocus using the field table and calculation rules, then run the tool.
Read keyDate, requirementFocus, 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
requirementFocus	ISO 6425 diving-time indicator focus	string; one of "scope", "resolution", "analogueMarkings", "handlingProtection", "unidirectionalBezel"	Required

Select an exact supported requirementFocus 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
keyDate	Standard or design context	string
requirementFocus	ISO 6425 diving-time indicator focus	string
verifiedStatement	Verified ISO 6425 statement	string

{
  "input": {
    "requirementFocus": "resolution"
  },
  "output": {
    "keyDate": "ISO 6425:2018",
    "requirementFocus": "resolution",
    "verifiedStatement": "The diving-time indicator must read elapsed diving time with a resolution of one minute or better over at least sixty minutes."
  }
}

Limitations and assumptions

The lookup describes stored ISO 6425:2018 topics and does not test a watch or verify a current certification. 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 COSC Mechanical Test Program Lookup: Look up a published component of the historic ISO 3159-based COSC mechanical chronometer movement test program. For a complementary task, use MIL-PRF-46374 Field Watch Specification Lookup: Return the active DLA status, historical MIL-W name, low-light scope, or attribution cautions for the general-purpose field-watch specification.
