During the 1970s, Omega was busy plotting the future of the Speedmaster. The most recognized prototypes from this era used the "Alaska" codename, but there were plenty of other rare examples being created and tested as well. Both of these watches were produced in 1974 in the aftermath of the Apollo program and exhibit several features that would become part of the consumer line of Speedmasters. The watches both employ a tonneau-shaped stainless steel case and are powered by the famous Lemania 5100 based Omega caliber 1045 movement that was used for the actual Alaska III prototype and later for the Speedmaster that respected collector Chuck Maddox dubbed "The Holy Grail" of Speedy movements. Available at auction from Christie's, both timepieces are extremely rare — but the Ref. 11001, which shows the most wear due to harsh testing by both OMEGA and the Swiss Institute is the only known example of a post-NASA test result watch.
