Omega Speedmaster Professional Moonwatch Sapphire Sandwich (3573.50.00)

July 15th, 1975 marked the beginning of an important chapter in space exploration. On that day the United States launched an Apollo rocket, referred to as the Apollo Soyuz Test Project (ASTP) Command Module and the Soviet Union sent Soyuz 19 into space.

Two days later a remarkable thing happened: the two spacecraft representing these former adversaries in the space race docked and the three astronauts and two cosmonauts met in the middle where they shook hands, exchanged gifts and spoke with each other as they orbited the Earth.
The ships remained docked for 44 hours after which they separated, and manoeuvred to use the Apollo to create an artificial solar eclipse which allowed the crew of the Soyuz to take photographs of the solar corona. Another brief docking was made before the ships concluded their own journeys separately. The Soviets remained in space for five days altogether, the Americans for nine.
It was the first time that spacecraft built by different nations had docked and signalled an era of cooperation in space which would lead to the efforts to build a permanently occupied space station. The mission also marked the end of an era - it was the final flight of the Apollo spacecraft.
While the Apollo-Soyuz mission is best remembered for its political significance, it also resulted in some major technological achievements as neither of the spacecraft, which were completely different from each other, had been built for the purpose of docking.
The American crew was commanded by Thomas Stafford and included Vance Brand and the last of the original seven Mercury astronauts to make it into orbit, Donald K. "Deke" Slayton who had long been grounded due to a heart problem. The two-man Soviet crew included Valeri Kubasov and the first space walker, Alexei Leonov.
The ASTP Command Module splashed down on July 24th, 1975 after 217 hours, 30 minutes in space.

The Apollo era had ended. It would be six years before another American astronaut would fly in space aboard the reusable Space Shuttle. All of the Shuttle astronauts were equipped, of course, with OMEGA Speedmasters.

THE OMEGA SPEEDMASTER PROFESSIONAL APOLLO-SOYUZ "35TH ANNIVERSARY"

When astronaut Lieutenant General Thomas P. Stafford (USA) and cosmonaut Lieutenant General Alexei A. Leonov (USSR) shook hands in the docking hatch which linked their respective spacecraft, the space pioneers, along with their crews, were wearing Omega Speedmaster Professional chronographs on their wrists.

Commemorating a handshake

The 35th anniversary of their historic handshake is commemorated with the release of the Omega Speedmaster Professional Apollo-Soyuz "35th Anniversary" chronograph in a limited edition of 1975 watches.

A meteorite dial

The dial has been created from a meteorite which survived its entry into our planet's atmosphere and the high-speed impact with the terrestrial surface. The meteorite's unusual structure is the result its very high temperature when it enters the Earth's atmosphere, followed by a period of cooling. The dial is a single piece cut from the meteorite; accordingly, because no two pieces of the meteorite are exactly alike, each watch in this limited edition is absolutely unique.

The black colour of the meteorite dial is the result of a surface oxidation process. The silvery seconds hand and chronograph counters appear in the meteorite's natural colour.
The Omega Speedmaster Professional Apollo-Soyuz "35th Anniversary" chronograph is a fitting tribute to a pivotal moment in space exploration. A handshake in orbit between these two former space race adversaries demonstrated to everyone back on earth that it was possible to move forward in a new spirit of cooperation.
