Abstract

PURPOSE:To provide the title method by which a real product can be distinguished from a forgery without fail and which makes forgery difficult. CONSTITUTION:A distinction mark 9 is made on the tip of the minute hand 6 of a watch 1 during watch production using a transparent ink containing a fluofescent material which emits fluorescence upon infrared irradiation. The tip of the minute hand 6 is irradiated with an infrared ray having a given wavelength capable of exciting the fluorescent material, and fluorescence from the mark is detected to judge this product to be real. The distinction mark can also be placed on the case 2, protective glass 3, dial 4, numerals 5 on the dial 4, hour hand 7, second hand 8, or other parts of the watch 1. The title method is applicable also to other products including bags.
