Full title and description

ISO 3158:1976 — Timekeeping instruments — Symbolization of control positions. This standard defines and specifies the designations (as symbols or words) for test/control positions used on any timekeeping instrument, regardless of type, design or dimensions.

Abstract

Provides definitions and standardized symbolization and wording for control/test positions on watches, clocks and other timekeeping instruments to ensure consistent indication and interpretation of positions (e.g., winding, setting, date-correction positions) across designs and manufacturers.

General information

• Status: Published (International Standard; confirmed following periodic review).
• Publication date: February 1976 (Edition 1, 1976-02).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 39.040.01 (Horology in general).
• Edition / version: Edition 1 (ISO 3158:1976).
• Number of pages: 3 pages.

Scope

Specifies the definition and designation (by symbol or words) of control/test positions for any timekeeping instrument irrespective of its type, design or dimensions — intended to be universally applicable to mechanical and other types of timekeeping devices to harmonize control-position markings and descriptions.

Key topics and requirements

• Standardized names and symbols for control/test positions on timekeeping instruments (e.g., positions for winding, hand-setting, calendar adjustment).
• Guidance on how to present designations (symbol vs. word) so they remain clear across different languages and instrument designs.
• Applicability to all timekeeping instrument types and sizes — emphasis on consistent user interpretation and technical documentation.
• Short, normative specification intended for incorporation by manufacturers and technical publications rather than extensive procedural requirements.

Typical use and users

Used by watch and clock manufacturers, product designers, technical writers, service/repair technicians, conformity assessors and standards committees to ensure consistent marking and documentation of control and test positions on timekeeping instruments.

Related standards

Adopted or referenced in various national/sector collections (for example DIN's adoption as DIN ISO 3158). It is a concise, stand‑alone international normative reference for horology-related definitions and may be cross-referenced by other horology and measurement standards dealing with user interfaces and mechanical functions of timekeeping devices.

FAQ

Q: What is this standard?

A: ISO 3158:1976 is an International Standard that defines and specifies the symbolization and wording used to designate control/test positions on timekeeping instruments (watches, clocks, etc.).

Q: What does it cover?

A: It covers the definitions and acceptable designations (symbol or words) for control/test positions, applicable to any type, design or size of timekeeping instrument to ensure uniform interpretation.

Q: Who typically uses it?

A: Manufacturers, designers, technical documentation authors, repair/service personnel and standards bodies in the horology sector.

Q: Is it current or superseded?

A: ISO 3158:1976 is published and has been through ISO’s periodic review process; the 1976 edition remains the published edition and was confirmed during review activity (ISO record shows confirmation following review cycles). Users should check with national/industry adopters for any national amendments or adoptions (for example DIN adoption activities noted in later collections).

Q: Is it part of a series?

A: It is a standalone ISO standard addressing symbolization of control positions for timekeeping instruments; it is related in subject matter to other horology and measurement standards but not presented as a numbered series with sequential parts.
