Inspired by a waterproof watch from 1931, it features a distinctiveyet classic design,housed inarare platinum case.

The Collection Prive Cartier Paris

In the last decade of the 20th century, the industry was still recovering from the impact of the quartz crisis, with consumers just starting to redevelop an interest in mechanical watches. In the midst of this, Cartier aimed to reestablish its credibility as a true watchmaking manufacture. From 1998 to 2008, the Collection Prive Cartier Paris brought back some of the most iconic Cartier designs from the past century, from the to the ,combined with high quality mechanical movements. In many cases, these distinctive designs hadnt been produced for decades, speaking to the jewellers desire to place an increased focus on its heritage.

All the Collection Prive Cartier Paris - or CPCP for short - pieces housed high-quality mechanical movements, at a time when the jeweller was mostly associated with quartz. Not possessing the mechanical knowledge in-house, Cartier relied on a range of external suppliers, such as Jaeger-LeCoultre, Frdric Piguet, Piaget or - a collaborative movement manufacture between , Denis Flageollet and . All the movements were manual-winding, rather than automatic, emphasising the traditional nature of this project.

All the Collection Prive Cartier Paris watches feature small, distinctive details, intended to set them apart. With the exception of the Cintre, all of them are signed Cartier Paris on the dial, a subtle nod to their vintage pieces. They also display a central rose motif just beneath the hands, which radiates into a classic guilloch. Even the subtle engravings on the caseback are reminiscent of what they used to do in the early 20th century. As for the manual-winding movements, these were finished in-house by Cartier, with their interlaced double C pattern appearing across the collection.

Despite the brands global reach at the time, the Collection Prive models were produced in small quantities, with many explicitly limited to 50, 100 or 150 pieces. As for those that werent marked as part of a numbered series, evidence suggests that production often remained between 200 to 500 pieces. Eventually, partially due to difficulties and delays in getting parts from their various suppliers,theCPCPprogram came to an end.

The Tank Vis

When the wristwatch replaced the pocket watch, one of the first objectives was to make it waterproof. Despite being at a disadvantage because they produced rectangular watches, Cartier still tried to join in with this effort. Rumours suggest that the Pasha de Marrakesh wanted a wristwatch that he could wear whilst in the pool, which led to the development of the in 1931. Thanks to its ingenious case design, tightly secured by screws, it was waterproof.

The Tank tanche served as inspiration for the Tank Vis, which was later introduced as part of the Collection Prive Cartier Paris. This later design features the same distinct bezel construction as the vintage inspiration, with Cartier also adding four visible screws on each corner. The Tank Vis was available in time-only, wandering hours and dual time versions, across a range of precious metals.

A Classic Design

This time-only Tank Vis represents the purest incarnation of the design. It is made out of platinum, which is the most rarely used metal across the Collection Prive Cartier Paris. The case follows the classic lines of the original Tank from 1917, which was inspired by the Renault tanks which Louis Cartier saw in use on the Western Front. The polished bezel features an arched shape, sloping down as it reaches the extremities of the case. It is secured in place by four screws on each corner, which give it a distinctive appearance, setting it apart from other designs.

The top portion of the lugs are also polished and gently slope towards, resulting in a rounded and elegant profile. The sides of the case are brushed, which also creates an interesting interplay of textures, with a sapphirecabochon bringing a touch of colour. The case measures 27mm by 31mm, with a lug to lug length of 39mm. This allows the watch to remain classic in appearance, whilst also being suited to contemporary tastes. At 8mm in thickness, it also manages to maintain some presence on the wrist and easily fits under the cuff of a shirt. As with all platinum pieces from the CPCP series, this Tank Vis features a closed caseback, with a brushed finish.

As is to be expected, the dial is signed Cartier Paris at 12 oclock, a nod to some pieces from the early 20th century, which had the citys name inscribed below the brand. The dial is made out of 18 carat gold, featuring a central rose motif just beneath the hands, which radiates into a traditional guilloch. Evidence suggests that the inspiration for this central rose came from vintage Cartier clocks, which often featured the distinctive decoration. The rail track and Roman numerals are stamped directly onto the dial in black ink, whilst the blued steel hands are executed in a legible sword shape.

The Movement

This platinum Cartier Tank Vis is powered by the Calibre 437MC, which is based on a Piaget bauche. Piaget helped develop a range of calibres for the Collection Prive Cartier Collection, drawing on their mechanical expertise, notably in the field of ultra-thin movements. The manual winding nickel lever movement features 18 jewels and a mono-metallic balance.
