Below is some history "So I used my wrist watch for time," Gordon Cooper Faith 7

Accutron Astronaut seen on Gordon Cooper's Wrist Prior to Faith  7

Gordon Cooper - MA-9 Faith 7 -  Omega Chronograph & Bulova Accutron Astronaut:  The final Mercury Mission on May 15th, 1963,  sent Gordon Cooper into space for 34 hours,19 minutes and 49 seconds  orbiting the earth 22 times.  He piloted the Mercury-Atlas 9 or Faith 7 and slept some.  This particular mission emphasized the need for instruments not reliant on the instrument panel.  The X-1 pilots like Chuck Yaeger of Rolex wristwatch fame and the first pilot to break the speed of sound, joked that the Mercury Astronauts had no need to "pilot" the spacecraft, as the crafts were designed for fully automatic control.  He described the Mercury 7 as "Spam in a Can".  He was proven quite wrong ,though,when due to technical problems Gordon Coopers Space capsule lost power. The situation became dicey when CO2 levels and temperature levels rose. Gordon Cooper mastered the controls and using his celestial knowledge was able to calculate the correct pitch for re-entry into the earths atmosphere. Making even a slight miscalculation would have been grave.  A sharp angle into the atmosphere would result in destructive g-forces, a too shallow trajectory would cause the tiny capsule to bounce off the atmosphere and head back into space.  Amazingly Cooper used the capsule window to draw lines determining the precise orientation before firing the reentry rockets.
So I used my wrist watch for time," he later recalled, "my eyeballs out the window for altitude. Then I fired my retrorockets at the right time and landed right by the carrier." (via Wikipedia)

Gordon Cooper's Bulova Accutron Astronaut

So which wrist watch did he use?   In actual fact Gordon Cooper was wearing two wristwatches: An Omega Chronograph and a Bulova Accutron.  As to which watch he used for reentry calculation - well the Omega Speedmaster enthusiasts will say an Omega Speedmaster and the Bulova Accutron collectors will say the Accutron. Although the majority are on the side of the Omega Speedmaster - Most of the consensus rests on the fact that Gordon Cooper brought the Bulova Accutron along on Faith 7 to double check the timing of the Omega Speedmaster. Gordon Cooper used the Omega Speedmaster to monitor the firing sequence of the retro rockets for atmospheric reentry. Upon returning, NASA presented Gordon Cooper with a Timex Wristwatch as a welcome back gift.  This watch cropped up at a Heritage Auction in 2009 together with a letter written by Gordon Cooper himself, acknowledging the authenticity of the watch. With the return of Gordon Cooper in the Faith 7 the Mercury Era had ended and NASA had their sites set on the Gemini and Apollo Missions.  Every component and aspect of the Mercury Missions were analyzed by a crew of newly appointed NASA engineers.  New equipment and instruments including wristwatches worn by the astronauts  were chosen for rigorous testing.
