The present reference reprises Omega's famous Calibre 321, which is visible through the sapphire crystal caseback. The 39.7mm case is inspired by the original 3rd generation Speedy (reference 2915-3) at which point the case size was increased from 38mm. The bezel ring is polished black ceramic with a white enamel tachymeter scale. Other familiar features include a stepped black dial, 'moonwatch' hands and a vintage Omega logo.
