SIGNED OMEGA, SPEEDMASTER PROFESSIONAL MODEL, REF. ST 145.022 -69 ST, MOVEMENT NO. 30'589'960, MANUFACTURED IN 1970

The reference 145.022-69 ST is the last model Speedmaster where the case back makes no reference to the moon landing. This model is also the first to have a painted Omega logo, rather than an applied metal one. The present model features a stepped dial, a rare and extremely sought-after “dot over 90” bezel”.
