Chopard Dual Time XL 'Onyx & Diamonds' Tank | Reference 5093/1
An Oversized Dual-Time Rarity from the 1970s
The Chopard Dual Time XL Tank, Reference 5093/1, is an opulent and highly distinctive creation from the golden design era of the 1970s. Crafted in solid 18K yellow gold and shaped in a commanding oversized tank case (24 x 46 mm), this dual-time marvel combines horological ingenuity with sculptural aesthetics.
Its standout feature: a dramatic black lacquered dial designed in the spirit of onyx, contrasted by a factory pavé-set diamond subdial at the bottom-right corner—a sparkling second time zone that radiates vintage glamour.
A Dual Heartbeat in Gold
Housed within the gold case are two independent manually-wound mechanical movements, each with its own dedicated L.U.C.-signed crown—original and untouched. This clever architecture allows two time zones to be tracked simultaneously, a rare function at the time, especially in a watch that looks more like a jewel than a tool.
The construction is robust and artful, a fine example of Chopard’s creative watchmaking during the pre-Quartz era.
No Retailer Signature—Pure Manufacture Provenance
Most examples of Reference 5093/1 were retailed under Kutchinsky in London, often featuring co-signed dials. This particular specimen, however, bears no external retailer stamp, allowing the pure Chopard design and craftsmanship to shine unadulterated—an important distinction for purist collectors.
Dial, Condition & Service
The dial remains in overall great condition, with minor but present marks in the top-left and bottom-left quadrants. These imperfections remain discreet and go largely unnoticed during wear. The black lacquer finish plays beautifully with light, while the diamond pavé second dial remains dazzling and intact.
The mechanical integrity has been fully restored by our in-house watchmaker, and the piece is backed by a 12-month warranty.
