Full title and description

STB BS ISO 1413-2016 — Horology — Shock-resistant wrist watches. This designation refers to the international standard ISO 1413:2016 (third edition), published by ISO and adopted/published as BS ISO 1413:2016; here presented as the STB/BS national adoption reference. The standard specifies minimum requirements and test methods for assessing the shock resistance of wrist watches.

Abstract

ISO 1413:2016 defines minimum requirements for shock-resistant wrist watches and describes corresponding test methods. The procedures simulate accidental shocks such as a watch falling from a height of about 1 metre onto a horizontal hardwood surface (or an equivalent test surface). The standard covers apparatus, test conditions, pre-test settings, shock procedures (including strikes to the watch head and free-fall tests on complete watches), and post-test acceptance checks.

Scope

The standard applies to wrist watches and defines a reproducible test regime to assess their resistance to accidental shocks. It is intended for use in type approval, quality verification and comparative testing rather than as a 100% production inspection method. Test sequences include controlled strikes to the watch head (specific positions) and free-fall impacts of the complete watch fitted with its wristlet, together with requirements for test apparatus, environmental/test conditioning, pre-test settings and post-test performance checks.

Key topics and requirements

• Definition of shock types and characteristics representative of a 1 m fall onto a horizontal hardwood surface.
• Detailed test apparatus and test-piece mounting arrangements (strike device and free-fall set-up).
• Pre-test conditioning: temperature, water-resistance prerequisites and preliminary rate or timing settings for mechanical and quartz watches.
• Specified shock procedure: positions for strikes (e.g., flank at 9 o’clock, crystal, crown) and the sequence/number of impacts.
• Free-fall test procedure for complete watch with wristlet and specified acceptance criteria after impacts.
• Post-test inspections and performance checks, including appearance, function and timing/rate limits; for water‑resistant watches, additional water‑tightness checks.
• Pass/fail criteria and reporting requirements for test results.

Typical use and users

Manufacturers and designers of wrist watches use this standard to design and validate shock-protection systems and to demonstrate robustness. Test laboratories and quality-control departments apply the methods for type testing, conformity assessment and R&D. Importers, retailers and certification bodies may reference ISO 1413 when specifying requirements for marketed products. The standard is also referenced by related horological and product standards (e.g., divers’ watch requirements) where shock resistance is a criterion.

Related standards

Relevant horology standards commonly referenced alongside ISO 1413 include ISO 6425 (divers’ watches — performance requirements), ISO 764 (magnetic-resistant watches), ISO 22810 (water-resistant watches), ISO 3159 (wrist-chronometers with spring-balance oscillators) and horological vocabulary/terminology standards. National adoptions of ISO 1413 (for example BS ISO 1413:2016) provide the text with national forewords and publishing details.

FAQ

Q: What is this standard?

A: ISO 1413:2016 is the international standard that specifies minimum requirements and test methods for assessing the shock resistance of wrist watches; it has been adopted by national bodies and published as BS ISO 1413:2016 (referred to here as STB BS ISO 1413-2016 for a national adoption reference).

Q: What does it cover?

A: It covers test apparatus, environmental and pre-test conditions, a sequence of controlled strikes to the watch head and free-fall impacts of the complete watch, and post-test inspections and acceptance criteria intended to simulate accidental drops from approximately 1 metre onto a hard horizontal surface.

Q: Who typically uses it?

A: Watch manufacturers, designers, testing laboratories, quality assurance teams, certification bodies, importers and retailers who need to evaluate or specify shock resistance for wrist watches.

Q: Is it current or superseded?

A: The third edition published in 2016 is the current ISO edition; it was subject to periodic review and is the operative edition noted as ISO 1413:2016. National adoptions (for example BS ISO 1413:2016) reflect the same technical content with national publication details.

Q: Is it part of a series?

A: ISO 1413 is part of the body of horological standards produced under ISO/TC 114 (horology). It is often used together with other horology standards (for example ISO 6425 for divers’ watches, ISO 764 for magnetic resistance, ISO 22810 for water resistance) to define broader performance requirements for watches.

Q: What are the key keywords?
