Your comments on this draft are invited and will assist in the preparation of the consequent standard. Comments submitted will be reviewed by the relevant BSI committee before sending the consensus UK vote and comments to the international secretariat, which will then decide appropriate action on the draft and the comments received. If no comments are received to the contrary, then the UK will approve this draft. If the international standard is approved, it is possible the text will be published as an identical British Standard. UK Vote Please indicate whether you consider the UK should submit a negative (with reasons) or positive vote on this draft. Submission The guidance given below is intended to ensure that all comments receive efficient and appropriate attention by the responsible BSI committee. Annotated drafts are not acceptable and will be rejected. All comments must be submitted, preferably electronically, to the Responsible Committee Secretary at the address given on the front cover.

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 2. The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1112 was prepared by Technical Committee ISO/TC 114, Horology, WG3. This third edition cancels and replaces the second edition (ISO 1112:1999), which has been technically revised.

Thus the number of functional jewels of a timekeeper is a sign of quality. The watch manufacturers use this fact to promote their products and some watch importing countries use it as a basis for defining custom duties. The extent of these stakes led to the creation of the ISO 1112 standard, in order to specify what are horological functional jewels.

It describes the different types of jewels used, and how this is to be marked on a time-keeping instrument or used in advertising. 2 Normative references The following referenced document is indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 6426-2, Horological vocabulary Part 2: Technical and commercial definitions 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 6426-2 and the following apply. 3.1 horological jewel non-metallic components whose hardness is higher than 1200 Vickers. 3.2 functional jewel horological jewel which serves to stabilize friction and to reduce the wear rate of contacting surfaces of the components of a timekeeping instrument and which satisfy the criteria of clause 4. NOTE Based on ISO 6426-2 3.3 non-functional jewel horological jewel that does not satisfy the criteria of clause 3.2 Licensed Copy: London South Bank University, London South Bank University, Fri Feb 15 05:45:00 GMT+00:00 2008, Uncontrolled Copy, (c) BSI ISO/DIS 1112 2 © ISO 2007 All rights reserved 4 Functional jewels The following are considered as functional jewels, whatever their shape. 4.1 Jewels with holes serving as radial or axial bearings (or both) a) Fixed, with movable arbor (see Figure 1). b) Movable, with fixed arbor (see Figure 2). Key 1 Movable arbor Figure 1 Key 1 Fixed arbor Figure 2 4.2 Jewels without holes, serving as axial bearings a) Fixed, with movable arbor (see Figure 3). b) Movable, with fixed arbor (see Figure 4).

Key 1 Movable arbor Figure 6 Key 1 Fixed arbor Figure 7 4.5 Jewels contributing to the transmission of a force or movement, or both simultaneously Examples are jewels used for the maintenance of an oscillating system with pallets in accordance with ISO 6426-2. 4.6 Jewelled units comprising several jewels Examples are ball-bearings or clutch devices for automatic winding mechanisms. Each unit should be counted as a single functional jewel in the description and marking of the instrument (see clause 6).
