Vacheron Constantin Ref. 1205V/100A-B590 — Variants and collector names
Known as: OQ 33, Overseas Quartz 33, Denim Blue OQ, Ladies Overseas Quartz Steel Diamond
Production phases and changes
- 2024: Successor 1225V/200A-B590 introduced: fully integrated bracelet (no more quick-change adapter), case code change 100A → 200A, caliber update to Cal. 1207 AS
The Vacheron Constantin Overseas 1205V/100A-B590 is known in collector circles as the OQ 33 or Overseas Quartz 33 — a 33 mm ladies' watch in stainless steel with a diamond bezel and a characteristic denim-blue dial. For many buyers, it flies under the radar because it runs on a quartz movement. That's short-sighted: the 1205V is the entry point into the Overseas world on the pre-owned market under $5,831 while its automatic siblings trade significantly higher.
## What 2024 Changed on the Pre-Owned Market
In 2024, Vacheron replaced the entire 1205V line with its successor, the 1225V/200A-B590. The new model's fully integrated bracelet does away with the quick-change adapter — three interchangeable straps come included straight from the factory. The case code moves from 100A to 200A, and the caliber update introduces the Cal. 1207 AS. The previous case thickness of 9.02 mm changes with this revision. On the secondary market, this model refresh has opened up a clear price gap: 1205V examples sit lower, while 1225V pieces trade at a premium. For buyers drawn to the classic variant, that's a compelling argument in their favor.
## Why the Denim Dial Holds Up Over Time
The blue of the 1205V/100A-B590 is not a one-season trend color — it has held its own as a distinct color position within the Overseas line for years. At 33 mm, the watch wears smaller than the 41 mm men's model, but the sports watch DNA remains fully intact. The diamond-set octagonal bezel is not a cosmetic upgrade bolted on as an afterthought; it is a defining design element of this variant. Buyers of the Ladies Overseas Quartz Steel Diamond get a watch that navigates between sport and jewelry without collapsing into either category.
Brand profile: Vacheron Constantin
Vacheron Constantin (founded 1755) is part of the 'Holy Trinity' of watchmaking and sits in the absolute luxury segment ($17,493-$583,100+). Counterfeits concentrate mainly on the Overseas, Patrimony, and historical models. The brand is counterfeited less often than Rolex/AP, but super clones from top Chinese factories (VS, ZF) reach dangerously high quality.
- Maltese Cross on the crown: On fakes it's often stamped too flat, with blurry edges and the wrong relief ratio. Genuine pieces have razor-sharp contours with a specific depth of ~0.15mm
- Guilloché depth and regularity: Machine-guilloché dials (Patrimony, Traditionnelle) show absolutely even depth on genuine pieces. Fakes have microscopic irregularities, sometimes stamped rather than cut
- Geneva Seal (if present): Must be visible on the movement with a serial number reference. Fakes often just print it on; the genuine seal is raised-engraved with a specific hallmark
- Automatic rotor movement finishing: Côtes de Genève must be perfectly parallel, edges hand-beveled (45° angle, mirror-polished). Fakes show machine bevels or uneven striping
Serial number format: VC uses 7-8 digit serial numbers, engraved between the lug ends at 6 o'clock (modern models) or on the movement plate. Format varies by production year. Modern numbers since 2000 often begin with a 2-digit year code. The model reference is additionally engraved separately (e.g. 4500V/110A-B126). The engraving must look hand-engraved with slightly irregular depth, not laser-etched. The typeface is VC's proprietary serif font with characteristic details on the digits 3, 5, 8.

Buying guide: Vacheron Constantin Overseas
Market situation and price range
At $16,370 the Overseas sits in a segment where first owners sell regularly — clean pieces with box and papers are not uncommon. The jump from "good" to "very good" usually costs 1,000 to 2,000 euros more at purchase. You get that premium back on resale if the condition is preserved.
What to look out for when buying?
- Authenticity: The serial number and reference on the case must match the papers. A professional authenticity check of the Vacheron Constantin Overseas reliably rules out counterfeits.
- Condition: Check scratches on the case and bezel — professional refurbishment can leave traces.
- Service history: A documented service by the manufacturer or a certified watchmaker increases the value.
- Scope of delivery: Box, papers and warranty card make a noticeable price difference on the Overseas.
- Independent certification: The CPS-52 standard covers 52 checkpoints — from the serial number and the timing machine to water resistance. The result is secured on the blockchain and can be verified at any time.
