While you are reading this, the watchmakers at Halda are replacing the first sapphire crystal of the Space Module with the Hesalite crystal – a space proven material.
As you may know, it is mandatory to exchange the crystal before going to space due to safety precautions. Although the sapphire crystal is scratch resistant, it shatters if broken, making it a hazard in space. The Hesalite crystal, on the other hand, is more sensitive to scratches though almost impossible to shatter. Hence, making it more suited for space missions. Whenever an owner of the Space Module is going to space Halda will exchange the sapphire, and now it is time again.
Earlier, the Halda watch was tested by Swedish astronaut Christer Fuglesang onboard the space shuttle Discovery, and now it´s time for Halda to enter space again onboard a Russian Soyuz rocket, this time with another astronaut.
