Description

[Detailed explanation of the idea] The present invention relates to the structure of a watch dial.

Generally, the conventional manufacturing method for watch dials is as follows:
As shown in Figure 1, in order to improve the three-dimensional effect and decorativeness,
A method has been adopted in which the abbreviations 2, marks, names, window frames 3, etc. are fixed to the dial 1, but due to the strength and processing of the dial, the dial body, abbreviations, marks, names, window frames, etc. The thickness of 0.2 to 0.3 m/m or more is required.

Therefore, the total thickness of the dial including everything is 0.4 ~
Wristwatches that were required to be thin (0.6 m/m or more) had to be printed with abbreviations, marks, names, window frames, etc., which resulted in the drawback of a monotonous, flat appearance. Furthermore, in order to change the surface pattern, color tone, etc., a huge number of man-hours are required for masking processing, which has the disadvantage of being a major factor in increasing production costs.

This invention solves the above-mentioned conventional shortcomings,
The object is to provide a dial having a three-dimensional appearance without increasing the total thickness of the dial, including the abbreviated characters, marks, names, window frames, etc.

Another purpose of the present invention is to expand the variety of designs by changing the patterns and colors of the dial body, abbreviations, marks, names, window frames, upper dial plate, etc. In other words, one dial plate is divided into multiple thin metal plates, and the dial body, which serves as one of the substrates, has abbreviated characters,
The mark, name window frame, etc. are fixed, and the other dial top plate provided with the through hole is closely fixed to the dial body. Furthermore, by applying the same or different patterns and colors to each board, the purpose was achieved through a synergistic effect.

A detailed explanation will be given below based on examples.

Example 1 In Fig. 2, a is a plan view, and b is a sectional view of the main part.The dial body 1 is made of 0.12 mm thick phosphor bronze material, and after plating, 0.2 mm thick material is used. Abbreviation 3
Keep it fixed. Next, a pattern is applied to the surface of the dial upper plate 2, which is pressed out from a 0.2 mm thick phosphor bronze material, and after plating and lacquer spraying are applied, it is adhesively fixed to the dial body 1. At this time, the through hole in the abbreviated character part of the upper dial plate 2 is formed by press punching so as to have a larger gap than the abbreviated character, and the through hole for the minute scale 5 is also formed by press punching. be. When colored plastic 4 was filled in the gap between the abbreviated letters fixed to the dial body and the through-hole on the top of the dial, and the through-hole that became the minute scale, a dial that looked like it was inlaid with natural precious stones was created. I was able to obtain Also, because the dial surface is flat, hours, minutes,
By attaching the seconds display hand 6 very close to the dial surface, errors in reading hours, minutes, and seconds can be significantly reduced.

As shown in the above embodiments, the present invention is capable of providing contradictory characteristics of thinness and three-dimensionality at low cost, and is of great significance. We also changed the size and shape of the through-holes on the top of the dial, and changed the color tone of the colored plastic filled in the gaps.
Combining colors creates a wide range of variations, and is an extremely effective idea for expanding design variety.

Claims (1)

[Scope of utility model registration request] In a watch dial formed by closely fixing a dial body made of a thin metal plate with a pattern, surface treatment, etc. and a dial top plate, abbreviations, marks, and window frames fixed to the dial body. The dial top plate, which has a through hole formed to have a large gap and a through hole serving as a minute scale, is fixed to the dial main body, and the abbreviations, marks, window frames, and the top of the dial plate are fixed to the dial main body. 1. A watch dial, characterized in that the gap between the dial plate and the through hole forming the minute scale is filled with colored plastic.
