Sky-Dweller 336934 replica

As you all know, Rolex “doesn’t make” complicated watches, and it is true that there are not many complicated watches in the Rolex lineup for sale. The most complex Rolex is the Skywalker (officially called Skywalker, commonly known as Skywalker) with its calendar and dual time zone features. But that doesn’t mean Rolex lacks complication technology. Today, I’d like to talk to you about Rolex‘s conceptual technology, including the following one.

Rolex has many technology patents, but very few of them are “physical” and have been disclosed. The 7230 calibre, codenamed ELF, is the prototype movement of the Rolex Escapement Concept, which stands for echappement, lame, and flambage. It is a very rare “experimental prototype movement” that has been published by Rolex. Players need not doubt the authenticity of this movement, as it was sold at auction in 2018.

The Rolex ELF 7230 calibre, the prototype movement of the Rolex Constant Force escapement, was produced in 1998 with a total of 20 pieces. It can be seen that in the opening, there is a very thin “metal wire” that passes through the two “metal arms” on the left and right. This “wire” is the “constant force spring.” At the same time, we can see that there are 3 shock absorbers on the movement: the upper two are for the escape wheel, while the ELF 7230 movement has two escape wheels (usually, watches have only one), and the lower one is for the normal balance wheel.

When the movement is running, the two escapement wheels transmit power, and the “metal arm” pulls the “wire” constant force spring up and down. The constant force spring divides the power of the spring into sections of equal power to ensure that the movement always operates under the same and stable power. If the movement is insufficient and cannot reach the “power” required to pull the constant force spring, then the movement will stop running. This ensures accurate timekeeping.
