Overview
ISO 14368-1:2000 is an international standard published by ISO that defines the dimensions and tolerances for mineral and sapphire watch-glasses. Specifically, this standard applies to round, flat watch-glasses with diameters ranging typically from 8 mm to 35 mm. Its purpose is to ensure precise sizing and consistent quality in the manufacturing of watch-glasses, critical components that protect watch faces.
This standard is the first part of a series under ISO 14368, focusing exclusively on dimensional specifications. It provides a clear framework for manufacturers, designers, and quality control professionals within the horology industry, helping them meet global requirements for watch-glass production.
Key Topics
Scope and Applicability
Applies to round, flat mineral and sapphire watch-glasses commonly found in wristwatches. The specified diameter range covers the most typical sizes used in watchmaking from 8 mm up to 35 mm.Dimensions and Symbols
Defines important dimensional parameters such as:- Diameter (d) of the watch-glass
- Cylindrical side height (h₁)
- Heights of upper and lower slopes (h₂, h₃)
- Total thickness (t)
- Slope angles (α) for various assembly methods
Assembly Considerations
Differentiates dimensions based on whether the watch-glass is assembled with adhesive or a gasket, influencing slope heights and angles.Tolerance Grades
Establishes limit deviations and tolerances in accordance with ISO 286-1 and ISO 286-2 for high precision manufacturing.- Various grades prescribed depending on thickness and diameter ranges
- Special attention to tolerances ensures compatibility in assembly and durability of the watch.
Compliance with Other Standards
Cross-references normative documents ISO 286-1 and ISO 286-2 which relate to the ISO system of limits and fits covering tolerance bases and grades for holes and shafts, ensuring consistent and internationally recognized measurement controls.
Applications
Watchmaking Industry
ISO 14368-1:2000 serves as a key reference for manufacturers and suppliers of mineral and sapphire watch-glasses, guaranteeing dimensional accuracy during fabrication.Quality Control
Enables quality assessment professionals to measure watch-glasses against internationally accepted tolerances, reducing defects and variations in final products.Design Engineering
Assists horology designers to specify precise sizes and assembly parameters for watch-glasses, optimizing compatibility for models using adhesive or gasket mounting technologies.Supplier and Manufacturer Communication
Provides a common framework and language to specify and verify watch-glass dimensions between international stakeholders, enhancing supply chain efficiency.
Related Standards
ISO 14368-2
Covers the assembly of mineral and sapphire watch-glasses to the watch case by adhesive or gasket, complementing Part 1’s dimensional criteria.ISO 14368-3
Specifies qualitative criteria and test methods for evaluating the performance and quality of watch-glasses.ISO 286-1 and ISO 286-2
Provide foundational systems for limits, fits, and tolerance grades used in defining the acceptable dimensional variations within ISO 14368-1.
Summary
ISO 14368-1:2000 is an essential standard for ensuring that mineral and sapphire watch-glasses meet strict dimensional accuracy and tolerance requirements. Its application ensures consistency, interchangeability, and reliability in watch-glass production and assembly, supporting the quality demands of modern horology. By adhering to this standard, manufacturers achieve enhanced product standards and foster international cooperation in watch component manufacturing.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 14368 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 14368-1 was prepared by Technical Committee ISO/TC 114, Horology, Subcommittee
SC 13, Watch-glasses.
ISO 14368 consists of the following parts, under the general title Mineral and sapphire watch-glasses:
� Part 1: Dimensions and tolerances
� Part 2: Assembly to the case by adhesive or using a gasket
� Part 3: Qualitative criteria and test methods
