Vacheron Constantin lists Overseas Self-Winding watches in both 34.5 mm and 35 mm, but the half-millimetre difference is only one part of the comparison. The exact reference determines the case material, supplied bracelet and straps, and which specifications are documented. The 34.5 mm catalogue examples are steel and 5N pink gold; a documented 35 mm pink-gold example is reference 4605V/200R-B978.
Which Overseas references are 34.5 mm or 35 mm?
The Maison’s Overseas collection page lists Self-Winding models in both sizes, alongside separate high-jewellery models. Its English 2025–26 catalogue identifies two 34.5 mm references, while the UK product page documents one 35 mm pink-gold reference in detail.
| Size and reference | Case material | Documented supplied configuration | Movement |
|---|---|---|---|
| 34.5 mm — 4600V/200A-B980 | Stainless steel | Three interchangeable straps in stainless steel, leather and rubber, per the English 2025–26 catalogue | Calibre 1088 |
| 34.5 mm — 4600V/200R-H134 | 5N pink gold | Three interchangeable straps in 5N pink gold, leather and rubber, per the English 2025–26 catalogue | Calibre 1088 |
| 35 mm — 4605V/200R-B978 | Pink gold | Pink-gold bracelet, with dark-blue leather and rubber accessory straps | Self-winding calibre 1088/1 |
The catalogue details for the 34.5 mm watches come from Vacheron Constantin’s English 2025–26 catalogue. The 35 mm row is specific to the UK product page for reference 4605V/200R-B978. The current collection listing also includes 35 mm steel and pink-gold Self-Winding entries and 35 mm high-jewellery entries in white and pink gold; the models’ individual pages are needed to verify specifications not shown here.
What does the 0.5 mm difference tell you about fit?
It tells you the listed case diameter, not how either watch will wear on your wrist. The sources establish neither comparative wrist-fit measurements nor independent wear testing, so they cannot show that one size will feel more comfortable or suit a particular wrist better. Case material, bracelet or strap configuration, and the specific reference also differ across the available examples. If possible, compare the exact models on wrist rather than treating diameter alone as a fit verdict.

For reference 4605V/200R-B978 only, Vacheron Constantin’s UK product page lists a 35 mm case, 9.33 mm thickness and water resistance of 15 bar (150 m). It also specifies a transparent sapphire caseback and self-winding calibre 1088/1, with hours, date, minutes, central seconds and a balance-stop function. The page gives a 40-hour power reserve and a frequency of 4 Hz. These figures should not be assumed to apply to every 35 mm Overseas.
How should you compare the interchangeable straps?
Start with the complete reference, then confirm which bracelet and straps are included with that particular watch. The two 34.5 mm catalogue models each have three interchangeable straps, but their metal option follows the case material: stainless steel for 4600V/200A-B980 and 5N pink gold for 4600V/200R-H134. The 35 mm reference 4605V/200R-B978 is listed with a pink-gold bracelet and dark-blue leather and rubber accessory straps.

Vacheron Constantin highlights the interchangeable bracelet-and-strap system as part of the collection’s design. The system makes supplied configuration a useful distinction between references, but the manufacturer’s description does not establish independent claims about comfort or durability. Check with the Maison or an authorized seller that any additional strap is confirmed for your exact reference; generic straps should not be assumed to fit the interchange system.

- Confirm the reference. Match the full code—4600V/200A-B980, 4600V/200R-H134 or 4605V/200R-B978—to the seller’s listing and documentation.
- Verify material and included components. Check whether the listing is for a bracelet, accessory straps, or both, and confirm the materials against the specific reference.
- Use reference-specific specifications. The 9.33 mm thickness, 15 bar (150 m) water resistance, 40-hour reserve and 4 Hz frequency cited here belong to 4605V/200R-B978, not to the entire 35 mm range.
- Check local price and availability directly. The reviewed UK product page presents a price-on-request flow; it does not establish a universal price or availability in another region. Listings and stock can change.
Vacheron Constantin frames the collection around travel, describing it as conveying “the spirit of travel.” That is the Maison’s positioning, not evidence of independently tested travel performance.
