Among watch components, although the hands are small parts, they represent the craftsmanship requirements of Swiss watchmaking. However, some of the technologies and equipment for processing and producing watch hands are still monopolized by Switzerland. Due to the costs of certain technologies and craftsmanship, replica watches face difficulties in imitating the hands. Therefore, the craftsmanship of the hands can be used for authentication and sometimes serves as a reference for judging the authenticity of a watch. As the first step in the visual authentication of a watch, the hand pivot is also the first authentication point we observe. Abnormalities in the hand pivot are our first warning sign. Next, we will use practical examples to illustrate the role of the...
In the evaluation and authentication of Swiss mechanical watches, preliminary inspections of the movement’s operating conditions through manual adjustment and other methods are important links in watch authentication and evaluation. For example, using the characteristics of the movement for rapid identification, such as: Rolex’s instantaneous date change, Omega’s hourly quick date change, etc. Today, I will share how to identify the authenticity of a mechanical watch through the way its date changes. Ordinary calendar adjustment method Pull the crown out to the second position (date setting position) and turn the crown clockwise to test whether the date can be adjusted normally. Pull the crown out to the outermost position, toggle the hour hand to rotate 24 hours, and test whether...
The use of a mechanical watch timing machine is an important part of watch authentication and evaluation. Through instrument testing, we can observe whether the watch is operating normally and check for risks such as potential faults. For the special attributes of some brands, the authenticity of their movements can also be judged through instrument testing. Daily rate: The display of timing error within 24 hours. The chronometer standard is +6 to -4 seconds per day. Amplitude: The swing range of the balance wheel. The normal value is 250 – 320. Most watches need maintenance when the amplitude is lower than 220. Polarization: The swing value of the balance wheel’s axis. A value within 0.8 is normal; an excessively large...
