Only produced in 999 examples (each individually numbered on the caseback), this extremely rare yellow gold limited edition Speedmaster, was manufactured in 1992 to celebrate 50 years of the important calibre 27 CHRO C12 (Omega's first column wheel chronograph), which later became the famous "321".

Just serviced by Omega UK & under their warranty for two years, this beautiful 42mm black dial manually wound chronograph (calibre 863 with 72hr power-reserve) was also the very first Speedy to feature a sapphire crystal glass. Fitted to a brand new rich brown Omega alligator strap with yellow gold folding clasp, water resistant to 50m. Accompanied by an Omega box, service papers, and Omega archive certificate.
