The Vacheron Constantin Overseas reference 4500V/110A-B483 is a definitive expression of the maison's modern sport-elegance — a 41mm stainless steel three-hander with the manufacture's in-house Caliber 5100, presented on the tool-free interchangeable bracelet system that lets the wearer move between integrated steel, blue rubber, and brown alligator with no service intervention required. The Overseas line, originally launched in 1996 and substantially rearchitected in 2016, represents Vacheron Constantin's interpretation of the integrated-bracelet sport watch category, and the 4500V remains the entry into the collection's most recent generation. The case measures 41mm by 11mm, with the signature six-sided bezel architecture flowing into a polished and brushed steel case, topped by a domed sapphire crystal and finished with a sapphire display caseback. The glossy black dial carries applied stick hour markers and dot accents at the five-minute positions, with luminous central hands and a date window at 3 o'clock. The Caliber 5100 is a self-winding manufacture movement, 30.6mm in diameter, beating at 28,800 vph with 37 jewels and a 60-hour power reserve, anti-magnetically protected by a soft-iron inner cage and visible through the open caseback. Water-resistant to 150 meters, the 4500V is the contemporary classic for collectors who want manufacture credentials without compromise. A 2020 example. Affirm financing available at checkout.
