Russian made mechanical movement

Movement complications

Raketa has 1 “caliber” with 4 different “complications”. A “caliber” (or base movement) is a mechanical movement in its most simple form, i.e. simply showing the time (hours, minutes & seconds). “Complications” are additional functions that are added on to the “caliber” and that therefore make it more “complicated”. The Raketa Watch Factory will gradually roll-out more complications over the next few years.  Stay tuned!

Hand-crafted movements

The components of the movement are not made with computer numerical machines (CNCs). They are made by hand using Russian “old school” production methods, by men and women who transmit a little of their soul into each component that they produce. You can visit the “Raketa Watch Factory” and see with your own eyes how our specialists work.

Interesting facts about Raketa watches (using the Raketa “Big Zero” as an example):

  • 8.201 operations are required to produce this watch
  • 242 specialists are needed to produce all of its components
  • 102 components (including that of the movement itself) are on your wrist when you wear this watch model

Inside the movement

Stopper of Self-winding unit

Disconnection of automatic winding module: The Raketa movement has a function that disconnects the automatic winding module from the rest of the movement when you wind-up the movement manually. This enables to prevent the tiny teeth of wheels in the automatic winding module from wearing out. Indeed, they are not meant to turn too quickly, which they would if they were not disconnected during the manual winding. This function was in particular developed for Soviet cosmonauts: in the absence of gravity in space, the rotor of the movement hardly moves and cosmonauts therefore have to wind the automatic movement manually during their long stays in space.

Rotor (or «oscillating weight»)

Rotor (or «oscillating weight»): This “weight” oscillates each time you move your wrist and thus automatically winds up the “main spring” (see below) through a series a small wheels (automatic winding function). The Raketa rotor has 2 particularities: it’s diameter is bigger than that of the movement itself, thus giving you a spectacular view on its oscillation. It is also bi-directional, which means that it winds up the movement in whichever direction it oscillates, thus doubling the self-winding efficiency rate. This was in particular developed for Soviet submariners who often had to stay still during long periods in cramped conditions in their submarines.

Main spring

Main spring: This is the source of energy of the movement (the equivalent of the battery in a quartz movement). Once this spring is wound up (manually by turning the crown of the watch or automatically with the rotor of the movement), it slowly unwinds in 40 hours by pushing forward all the gear train of the movement.

Balance wheel & hair spring

Balance wheel & hair spring: This module is the very heart of the movement and also the most complicated to produce and assemble. It is responsible for reducing the rotation speed of the gear train to precisely the right speed that is needed to turn each of the 3 hands on the dial. Produced with a precision of up to 0.5 micron (i.e. 0.0005 mm) from a secret Russian alloy, the hair-spring is calculated to oscillate exactly 18.000 times/hour. If it oscillated more (or less) slowly, the watch would then go too slowly (or too quickly)!

Close
Gear train

Balance wheel axis: This tiny axis (3.2 mm height) must be in conformity with 36 different measures. It oscillates around its 2 pivots (tips) 18.000 times/hour (i.e. approx. 500.000 times/day, 3.000.000 times/week, 12.000.000 times/month, etc). To avoid a premature wearing of the 2 metal pivots (tips) of this axis, they are “sitting” in bearings made out of rubis stones.

Close
Jewels

Jewels: The Raketa 2615 movement has 24 ruby stones. Their purpose is to reduce the friction at the points of heaviest wear, ex: where the 2 metal pivots (tips) of the balance wheel axis rub against their bearing at a speed of 18.000 oscillations/hour. If the bearings were in metal, the constant friction of 2 metal parts would be quick & devastating. Therefore, the bearing is made out of ruby which is one of the hardest stones on earth.

Close
Gear train

Gear train: The gear train is made of 13 gear wheels and pinions (a pinion is an axis with teeth). Depending on their diameter and their number of teeth, they turn at different speeds. Three of the wheels are directly connected to the respective 3 hands (hours, minutes, seconds) and are therefore responsible for the precise speed at which these hands move along the dial.

Decoration of the movements

We take great pride in decorating as well as possible our in-house made mechanical movement and showing it to you through the case back of the Raketa watch. All the decorations, whether mechanical or printed, are made by hand at the Raketa Watch Factory. The decorations try, as much as possible, to convey the story and the values of the watch model in which the movement is assembled. For example, the Raketa “Polar” watch which is made for Polar explorers, has a decoration reminding you of polar (northern) lights that you can see in the arctic sky.
