FORTIS Cosmonautis Official Cosmonauts Chronograph B-42 Ref. 638.10.11 M self-winding UW-50 cal.

On the ISS, this loyal partner can always be read with precision, even when used outside the station, thanks to its Super-Luminova coating. Solid stainless steel and sapphire crystal with anti-reflective coating on both sides also ensure that good feel that you need for such demanding missions. The precision of the Swiss automatic movement (ETA 7750) can even keep pace with the natural orbit speed of approximately 28,000 km/h and delivers absolute exactness. Of course, few of us will ever find ourselves repairing a sun sail on the ISS, but one thing is clear: with the FORTIS 638.10.11 Official Cosmonauts Chronograph, you will be perfectly equipped for challenges here on earth too. This watch has been the star of the FORTIS Cosmonautis Collection for decades.
