Case
SRE-Stainless Steel
Produced from the rocket motor
SRE stainless steel is produced using a metallurgical process. SRE stands for “Soyuz Rocket Engine”. The first step of the process involves the reduction of carbon to 0.17% (decarburisation). The second step involves the addition of 2.8% nickel and 2% molybdenum.
The story to the name
4.5 Megatons Chronograph
A glance at the Soyuz rocket from below gives you a direct glimpse into its red engines. This view was the inspiration for this model. The name “4.5 Megatons” is a nod to the rocket’s propulsive force. The model was introduced in 2015 as part of a seven-piece series.

Movement
Cal. 7750
The origins of perhaps the most successful Swiss automatic chronograph movement of all time date back to the year 1901, the founding date of the firm J & C. Reymond Frères S.A. Later, they continued to produce the legendary movement under a new company name, Valjoux S.A. The movement was all but made redundant during the Quartz crisi of the 1970s. Today, the ETA Valjouz 7750 is produced and distributed by ETA. Many of the world's best-known watch brands incorporate this movement into their timepieces in one form or another.

Soyuz rockets
To the frontiers of space and back
Soyuz rockets are launched in the Baikonur Cosmodrome in Kazakhstan and complete their journey into space in three stages. At a height of 45 km, the booster of the first stage is jettisoned. This is followed by the fairing at a height of around 85 km.
There are no fixed boundaries in space; rather, the transition between the Earth's atmosphere and space is fluid. The Fédération Aéronautique International (FAI), the International Air Sports Federation, has adopted Karaman's definition, setting the boundary at 100 km. For the US Air Force (USAF), space begins at 80 km. According to this definition, the Soyuz fairing components have crossed the boundary into space. These models can be idenitified by their white or white-red faces and the marking "Soyuz Fairing".
Soyuz TMA-18M
SOYUZ TMA-18M was the name of a flight mission to the International Space Station (ISS). It was the 44th visit of a Soyuz spacecraft to the ISS and the 150th flight in the Soyuz programme. The Soyuz spacecraft undocked Soyuz TMA-16M as a crew return vehicle since the Soyuz spacecraft have only a 210-day design life.
