The documented references share a 41.5 mm case, 8.1 mm thickness and 5 bar (50 m) water resistance, but differ in dial, calibre, edition status and listed straps. The UK page displayed £119,000 including tax for the burgundy-dial 4300V/220G-H151 when accessed in 2026; that is a regional price for one reference, not a guaranteed price for the whole family.
What are the Overseas Perpetual Calendar’s specifications?
Vacheron Constantin’s product pages for the documented references list an 18K white-gold case measuring 41.5 mm in diameter and 8.1 mm thick. They specify 5 bar (50 m) water resistance. These are manufacturer specifications, not independent test results.
The H151, B945 and H119 pages identify a self-winding calibre 1120 QP. For the H151, Vacheron Constantin lists a 29.6 mm movement diameter, 4.05 mm movement thickness, 276 parts, 36 jewels, a 40-hour power reserve and a frequency of 19,800 vibrations per hour (2.75 Hz). The skeletonized B946 uses the separately designated calibre 1120/3 QPSQN/1; its official page also lists a 40-hour power reserve.
The H151 page lists hours and minutes, hand-indicated day and month, leap-year indication, perpetual calendar and moon phase. Vacheron Constantin says its calendar “will display the correct date until 2100” and describes the moon phase as two gold moons against a starry sky. The H151 page also lists a transparent sapphire caseback, antimagnetic marking and Hallmark of Geneva certification.
How do the four documented references differ?
Reference numbers matter: dial finish, calibre designation, limited-edition status and supplied strap combinations are not identical across the family.
| Reference | Dial and edition | Calibre | Listed straps | Price information |
|---|---|---|---|---|
| 4300V/220G-H151 | Burgundy lacquered dial; edition status not stated on the official UK page. | 1120 QP | Burgundy and white rubber. | £119,000 including tax on Vacheron Constantin’s UK page when accessed in 2026. |
| 4300V/220G-B945 | Blue lacquered dial; edition status not stated on the international page. | 1120 QP | Dark-blue rubber and grained calfskin. | Not stated on the cited international product page. |
| 4300V/220G-H119 | Azure lacquered dial with tone-on-tone moon disc; manufacturer-described limited edition of 200 pieces. | 1120 QP | White and blue-denim rubber. | Not stated on the cited product page. |
| 4300V/220G-B946 | Skeletonized dial; edition status not stated on the cited page. | 1120/3 QPSQN/1 | Dark-blue rubber and grained calfskin, alongside the bracelet. | Not stated on the cited product page. |
Specifications, strap listings and availability can change; use the reference number to check the current listing rather than assuming another variant’s details apply.

What is the difference between the standard and skeleton versions?
The documented standard H151 and B945 have lacquered dials and use calibre 1120 QP. The B946 is the skeletonized version and lists calibre 1120/3 QPSQN/1. Its official page lists a bracelet as well as dark-blue rubber and grained calfskin straps. Those are reference-specific differences; the available specifications do not establish a difference in measured accuracy, practical performance or wearability.

Vacheron Constantin’s UK page showed £119,000 including tax for reference 4300V/220G-H151 when accessed in 2026. Treat that figure as the displayed retail price on one regional page at that time: it is neither a family-wide price nor a secondary-market valuation, and the official listing can change. The cited pages do not establish comparable prices for the other references, current global availability or resale values.

What to verify before choosing a reference
- Match the full reference number to the dial and movement you want; the skeletonized B946 uses a different calibre designation from H151 and B945.
- Confirm the current regional price and availability directly on the listing for that reference.
- Check the listed strap set against the exact reference. For replacement or alternate straps, confirm compatibility and clasp or buckle fit rather than assuming an accessory for another Overseas model will fit.
