A **replica** of the **Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin** (likely a counterfeit version of reference 4300V/000R-B509). It features a 41.5mm rose gold-tone case and integrated bracelet, a deep blue dial with perpetual calendar complications (day, date, month, leap year, and moonphase indicators), and 150-meter water resistance. **Note:** This is a fake—authentic Vacheron Constantin pieces are Swiss-made luxury timepieces retailing for over $90,000, not affordable mass-market items.
