Cartier Stepped Case Jumbo "New York" ref.15716 de 1975

This model is the Cartier Ref: 15176 (New York boutique version). This is the rarest variation of the Stepped Tank series. It was the only model that was gold-plated in a "brass" metal alloy case (the Paris and London variations were gold-plated on "steel" cases). It was produced around 1975-76 at the Cartier boutique in New York.

The reference 15715 was the only reference that had a "Four screws" back cover (the other models had snap-on cases), another important point to mention is the unusual crown with the elongated spinel cabochon and the slight area in the case design to protect the crown. This was the only reference that had serial numbers unlike the Paris and London versions. These case serial numbers in the stepped case should always start with the number 12-0 followed by its 4-digit case serial number. The other references did not have a serial number on the exterior of the case and were lightly/superficially engraved with the Cartier brand and text. The Stepped Case Jumbo had an ETA 2512/Cartier caliber 78-1 movement signed '' Cartier Inc '' (Only the Cartier ETA calibers from the US market were signed Cartier Inc). Serial number research indicates that only 2500 pieces were produced before production was discontinued at the end of 1976, making it an extremely rare and difficult-to-find watch in optimal condition due to the natural materials used.
