Omega Constellation (wife's)

Vintage Omega Constellation Automatic · "Officially Certified Chronometer" · cushion-case · green dial · currently non-functional

Non-functional · service required

Note 21 May 2026: photo captured (see below) — dial reads "Constellation Automatic · OMEGA Chronometer Officially Certified". Identified as Omega Constellation line — cushion-shape case, integrated jubilee-style steel bracelet, dark green dial with date window at 12 (showing "20"). Cushion-case Constellations were produced primarily in the 1970s (refs 168.0056 / 168.0057 / 168.0058 family). Hand-winding fault diagnosis below pre-dates this photo; revisit the diagnosis now that we know it's an automatic Constellation — see below.

Wife's Omega Constellation Automatic Chronometer Officially Certified — front view of the cushion-shaped stainless-steel case with dark green dial, applied steel hour markers, date window at 12 showing '20', signed 'Constellation Automatic' to the left and 'OMEGA · Chronometer Officially Certified' to the right of centre. Integrated jubilee-style steel bracelet. Vintage 1970s example, currently non-functional (winding mechanism issue per Dan).

Photo captured 21 May 2026 — used in the WatchRepair.net estimate exchange. Identification update: the dial confirms this is a Constellation Automatic (not a manual-wind De Ville / Genève / Seamaster). Cushion-case Constellation Automatics are the 1970s "C-shape" family — refs 168.0056, 168.0057, 168.0058 most likely. Caseback photo + serial number on next pass to lock the exact reference + production year.

Known faults (from Dan's reply 21 May 2026)

Used to work, but right now it's considered non-functional. Specifically: missing hand-winding mechanism. This means the manual-wind crown / arbor / clutch is either physically missing or seized — common on vintage Omegas after decades without service. Symptom: crown turns but no resistance / no power-reserve build-up.

A CW21-certified watchmaker can replace the keyless works (winding + setting components) from donor movement or parts stock. Estimated complexity: medium — depends on which calibre is inside.

Model line

Constellation (dial: "Constellation Automatic · OMEGA Chronometer Officially Certified")

Era

1970s — cushion-shape "C-shape" Constellation family (refs 168.0056 / 168.0057 / 168.0058 candidates). Confirm exact year from caseback serial.

Movement type

Automatic (dial confirms — earlier diagnosis assumed manual-wind which was wrong). Most Constellation Automatics of this era ran calibres 1011 / 1012 / 1020 / 1021. Hand-winding via crown is the secondary path on an automatic; the primary mechanism is the rotor. If the crown winds with no resistance, it's keyless-works wear; if rotor doesn't engage, that's a different repair.

Serial number

TBD — case-back engraving + inside movement

Current condition

Non-functional · sentimental keepsake · not serviced in 25+ years (confirmed via Dan's 20 Apr 2026 email). Operational status frankly unknown — could be a simple winding-mechanism fix or a complete movement overhaul depending on what's seized vs missing.

Estimated market value

$400 – $800 as-is (non-functional, 25+ years no service, condition unknown).
$1,200 – $2,000 post-service (running, serviced movement, original dial & bracelet preserved).
Range reflects 1970s C-shape Omega Constellation Automatic (cushion case, refs 168.0056 / 168.0057 / 168.0058 family) market on Chrono24 / WatchUSeek / Omega Forums sales threads. Green dial is a less common variant than silver/champagne — small premium. Sentimental value to wife exceeds market value at any point in the range; this is replacement-cost framing for insurance / inventory, not a sell signal.

Quoted price

Not yet quoted by WatchRepair.net — Dan's request asked them to estimate AFTER seeing it. Likely $399-600 range (similar to Dan's Speedmaster $399 baseline, possibly + parts for the missing keyless works). Two-watches-in-one-shipment confirmed by Hannah 23 Apr 2026 — saves a separate WatchRepairPak run.

Provenance

TBD — capture origin story (inherited / gift / purchased)

Current status

Non-functional; in service-decision flow. In conversation with WatchRepair.net — vintage-Omega specialist work. Wife wants confidence in the contractor before committing (BBB + references requested in Dan's reply 21 May 2026). Next steward action: photos of dial + case-back + movement (if openable) for estimate.

Approved contractors

Service / restoration: WatchRepair.net (Harriet Herman, FL) — vetting in progress · in conversation 21 May 2026. Same vendor as Dan's Seamaster overhaul; one shipping run could cover both watches.
Alternative path: Omega Vintage Service (factory) — for collectible pieces of historical significance. More expensive, longer wait. Only worth it if variant turns out to be high-value (e.g., Constellation pie-pan, early Seamaster, etc.).
Local alternative: a Bucks-County / Philly-area independent watchmaker, if one with vintage Omega experience is shortlisted. None identified yet.

External references — vintage Omega identification

Omega Forums: omegaforums.net — post photos in the "Vintage Omega" sub-forum for variant + value identification. Community is famously good at this.
