People have been skeptical that a watch can have both the day and the calendar function, and at the same time ensure the accuracy of the watch. Mainly because the mainspring needs to provide energy to make the date wheel turn properly. First, when the last hour of the day is coming to an end, a lot of energy is concentrated on rotating the date disc, which may affect the transmission between other gear trains; second, the date disc will cause friction on the movement dial, This affects the running time of the movement; in addition, the instantaneous jumping date may be insufficient or skipped.
For the above power transmission problems, fake Rolex solved it with a cam. Every minute of the watch, a part of the energy is stored on this cam, and when the date dial needs to be turned, the cam releases the energy. And the friction between the date plate and the movement, Rolex solved by adding gems between them.
The day calendar type is Rolex’s flagship series, and this series of watches can also enjoy the latest scientific and technological achievements of replica Rolex at any time. The first fake Rolex day-date watch was equipped with the Cal.1055 movement, and the free spring and screw fine-tuning balance wheel allowed replica Rolex’s day-date watch to maintain a competitive advantage at that time. By 1959, the Cal.1555 movement was born and used in the new day-date watch. Cal.1555 has a compensating screw balance wheel. Once it was launched, it was praised continuously, and it is known as the “most practical and luxurious” movement of Rolex. This movement had high accuracy and good shock absorption at the time, and its influence among watch friends still exists until now.
The stop-second ensures that the wearer can ensure that the second hand stops temporarily when adjusting the time of the watch, and realizes a more convenient and accurate time adjustment. Another change for fake Rolex day-date watches is the use of a sapphire crystal. Also in the 1960s, sapphire crystals began to be widely used on watches. The crystal of this material is not only not easy to scratch, but also fits the case better than the traditional acrylic crystal, providing better water resistance.
