Pocket watches converted into wristwatches hold a unique place in horological history, blending the elegance and craftsmanship of a bygone era with the practicality of modern wristwatches. These conversions typically involve adding lugs and a leather strap to the original pocket watch case, creating a timepiece that can be worn on the wrist while preserving its vintage charm. The Audemars Piguet Quantieme Perpetuel reference 25 726BA is an exquisite example of such a conversion, originally designed as a pocket watch and later transformed into a wristwatch officially by Audemars Piguet. Crafted in yellow gold, this timepiece features a beautifully detailed silvered dial with Roman numerals and multiple subdials, showcasing its perpetual calendar complications. The watch is powered by the manual-winding Audemars Piguet Caliber 5020, a movement renowned for its precision and complexity. The perpetual calendar function displays the day, date, month, and leap year, requiring no manual adjustment for months with varying lengths or leap years, making it a marvel of watchmaking engineering. The conversion retains the original case design, enhanced by the addition of gold lugs and complemented by a refined leather strap, making it suitable for modern wear. The Audemars Piguet Quantieme Perpetuel 25 726BA, with its serial number N°1, is a highly collectible piece, further authenticated by its accompanying box, warranty, and Certificat d’Authenticité. This watch is a testament to Audemars Piguet’s timeless craftsmanship, blending the historical significance of pocket watches with the functional elegance of wristwatches.
