Bangkok Luxury Watches: Celebrating 270 Years with a Bold New Release
Vacheron Constantin, one of Switzerland’s oldest and most revered watchmakers, is marking its 270th anniversary with the unveiling of two new dial variations of the Overseas Perpetual Calendar Ultra-Thin.

New Dial Aesthetics for 2025
The first model, reference 4300V/220R-H144, pairs a gold-toned lacquer dial with 18k 5N pink gold moon phase disc, hands, and hour markers, contrasted with blue accents that enhance legibility. The second edition, reference 300V/220G-H151, stands out with a rich burgundy lacquer dial paired with 18k white gold details and the same subtle blue highlights. Both watches are fitted on meticulously finished solid gold bracelets, yet each is accompanied by two interchangeable rubber straps. For the pink gold edition, straps arrive in white and blue, while the white gold version comes with white and burgundy options. Thanks to Vacheron Constantin’s quick-change system, switching styles is effortless.
Ultra-Thin Powerhouse Movement At the heart of these timepieces beats the Caliber 1120 QP/1, an ultra-thin automatic movement measuring just 4.05 millimeters thick. Despite its diminutive size, it manages to house the full range of perpetual calendar complications including day, date, month, leap year indicator, and a moon phase. The movement operates with a 40-hour power reserve and is certified with the Geneva Seal, a mark of prestige and superior craftsmanship. This movement is based on a heritage Jaeger-LeCoultre design but has been reimagined and perfected in-house by Vacheron Constantin.

Competition in the Ultra-Thin Arena
The Overseas Perpetual Calendar Ultra-Thin holds its place among the slimmest perpetual calendar watches in the world. It surpasses Audemars Piguet’s Royal Oak Perpetual Calendar at 9.5 millimeters and Patek Philippe’s reference 5940, which measures over 8.5 millimeters. However, the crown for absolute thinness still belongs to Bulgari, with its Octo Finissimo measuring just 5.8 millimeters. Still, what sets the Overseas apart is its unique combination of wearability, refinement, and enduring design.
Design and Craftsmanship
With its barrel-shaped case and the signature Maltese cross-inspired notched bezel, the Overseas line has been Vacheron Constantin’s answer to the luxury sports watch category since 2016. It was conceived to rival icons like the Patek Philippe Nautilus and Audemars Piguet Royal Oak. These new editions continue that legacy, offering a robust 41.5mm case diameter while retaining an astonishingly slim profile. The integration of micro-adjustable folding clasps ensures both security and comfort, while the overall finish of the gold bracelet stands as a testament to the maison’s artisanal mastery.
