The Patina and Plexi Omega Speedmaster 145.022 Protocol: Navigating the Calibre 861 Transition
The Patina and Plexi Omega Speedmaster 145.022 Protocol
The Omega Speedmaster 145.022-69 transitional step dial with Calibre 861 movement and Dot Over 90 bezel marks the exact moment Omega modernized their production line. If you are buying one today, you need to know exactly what you are looking at. The difference in price between an honest, original example and a watch cobbled together from service parts is thousands of pounds.
Visual OCR and Authenticity Verification
Authenticating a 145.022 comes down to the dial and the bezel. Unlike a Seiko 6159-7001 Hi-Beat 300m where the monobloc case condition heavily dictates the price, a vintage Speedmaster’s value lives right on its face.
The Dot Over 90 (DON) Bezel
If you are looking at a reference from 1968 or 1969, check the aluminum tachymeter bezel immediately. Find the number 90. The luminescent dot needs to sit diagonally above the zero—hence, “Dot Over 90.” If a watchmaker swapped it out for a later “Dot Next to 90” (DNN) service bezel, the value drops off a cliff. A correct DON bezel alone can swing the price from a £4,000 baseline straight past the £7,000 mark.
Step Dial Architecture
Early 145.022 dials are not flat. The central matte black section drops down into the outer minute track, creating a physical “step.” Under good lighting, this ridge casts a tiny shadow. Omega eventually flattened the dial in later iterations (like the 145.022-76), and modern service dials are completely flat as well. If a seller claims it is a ’69 but the dial is flat, walk away.
Technical Specifications & Market Valuation
Before you hunt for parts or project watches, know the baseline specs.
- Manufacturer
- Omega SA
- Reference
- 145.022 (Focusing on -68 and -69 Pre-Moon)
- Caliber
- 861 (Manual wind, cam-actuated chronograph)
- Current Market Valuation
- £3,800 (Late 70s Flat Dial) to £7,500+ (Pristine -68/-69 Transitional DON)
- Case Manufacturer
- Huguenin Frères (HF) or Centrale Boîtes (CB)
Always cross-reference the movement serial number with the production year. You can get primary source validation straight from the Omega Extract of the Archives to prove the watch left the factory exactly as it sits today.
Dealbreakers: Who This Is NOT For
Vintage Speedmasters look great, but they require compromises. Keep these realities in mind before buying:
- Zero Water Resistance: Do not swim with this watch. Vintage pump pushers and old gaskets cannot handle moisture. If you want a vintage aesthetic that can actually get wet, look at a Seiko 6105-8110 asymmetric case design instead.
- Heavy Service Costs: The Calibre 861 is tough, but overhauling an abused chronograph movement in the UK right now will easily cost you between £600 and £850.
- Dead Lume: Original tritium markers will not glow in the dark anymore. If you need a watch for night legibility, buy a modern reissue.
Asymmetrical Case Lug-to-Wrist Ratio Calculator
The 145.022 features twisted “lyre” lugs spanning 42mm in diameter but a lengthy 47.5mm lug-to-lug. Calculate if your wrist can actually support the case without overhang.
Market Acquisition Strategy
Finding a pristine transitional model requires patience. Do not compromise on the dial or bezel. When looking at auction sites, demand high-resolution macro photos of the dial step, the typography on the Omega logo, and the pusher threads.
