watches worn in space

Although the Omega Speedmaster is the most famous space watch, being worn on all moon missions, it is one of 7 watches which are NASA certified, including a range of far less glamorous Casio G-Shocks. Ironically, the watch which has possibly been in space most is one that costs a fraction of the price of a Speedmaster and is more associated with computer geeks - the Timex Datalink.

Rules as to what watches could be worn by Russian Cosmonauts were more relaxed, however, Poljot military watches were often worn. The Chinese have chosen the Fiyta Chronograph for their manned space missions.
