The Overseas Chronograph is the flagship sport complication reference; secondary prices are firm because in-house Hallmark of Geneva-certified chronograph movements at this price point are genuinely rare.
The 49150/422A-9079 is the previous-generation Overseas Chronograph in steel, running Vacheron's in-house Cal. 1141 at 43mm. It occupies a specific position in the market: a genuine manufacture movement, a column-wheel chronograph, and the Overseas name, all at prices that have softened considerably since the current generation arrived. Collectors who want the bones of this watch without paying a premium for a redesigned case will find it a strong choice.
Vacheron introduced this generation of the Overseas Chronograph in the early 2000s, and it ran in steel, rose gold, and two-tone configurations until the complete 2016 redesign that introduced interchangeable straps and updated case proportions. The Cal. 1141 is a column-wheel, horizontal-clutch automatic chronograph built on an ébauche base, delivering solid chronograph execution without flyback capability. The 43mm diameter was a deliberate step up from earlier Overseas pieces and positioned the watch against the Royal Oak Offshore and Nautilus chronographs of the same era.
The ref. 49150 in steel with the 422A-9079 designation points to the blue dial variant, which is the most collected configuration of this generation. Production volume was modest by sports-watch standards, keeping supply tighter than the larger gold references might suggest.
Verify the case is free of deep polishing, particularly along the integrated bracelet lugs and the chamfered surfaces; this case was over-polished by dealers and prior owners with surprising frequency. The bracelet stretch and clasp wear are worth examining in person because replacement bracelet links and clasps for this generation can be slow to source from Vacheron. Confirm both chronograph pushers engage and reset crisply, and check that the column-wheel operation has no hesitation, because any softness there signals wear that requires movement service.
On the dial, look for any moisture intrusion around the subdial rings or the date window, as this generation's gaskets age and the 50m water resistance rating was not conservative. Finally, confirm the reference number on the caseback matches the dial configuration you are buying, since components have been swapped between service donors on the grey market.
Steel examples of this reference have retreated meaningfully since the 2016-generation Overseas became established, and honest-condition pieces now trade in the $15,000 to $20,000 range depending on bracelet condition and service history. The blue dial commands a modest premium over silver or white dials. Two-tone and full rose gold variants have their own pricing logic and move more slowly.
A complete set with original papers and box adds perhaps 10 to 15 percent over a watch-only price, less than you might expect given how few of these come to market complete.
The Cal. 1141 calls for a full chronograph service roughly every seven to ten years, involving disassembly of the chronograph mechanism, a complete movement service, and resealing. Vacheron's boutique service is reliable but priced accordingly, typically in the $2,000 to $3,500 range for a full chronograph overhaul on this caliber. A small number of independent watchmakers with Vacheron experience can service the 1141 competently and at lower cost, but confirm they have prior experience with column-wheel Vacheron ebauche movements before committing.
Community + OSINT signals haven’t landed for this reference yet. We don’t publish a rating against zero signal — the number would mean nothing. Editorial body + caliber + market value still surface above; ratings appear once the signal corpus does.
Confirm Cal. 1141 at 36,000bph through the caseback and verify the column wheel; later Overseas chronographs use Cal. 5200 at a different beat rate.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| caseback | Cal. 1141 identity and column wheel | Cal. 1141 visible through caseback; column-wheel architecture confirmed; 36,000bph movement | Cal. 5200 in an earlier generation case; any non-column-wheel architecture |
| dial | Chronograph sweep hand behavior | Near-continuous sweep due to 36,000bph (5Hz) rate; smooth appearance under running seconds | Jerky step movement of the chronograph hand; inconsistent with the 5Hz beat rate |
| case | Earlier generation Overseas Chronograph case | Consistent case profile for the earlier generation; pusher positions and crown configuration matching original specifications | Case from a different Overseas generation mixed with an incorrect movement generation |
