In 1917, Louis Cartier took inspiration from the purity of the lines of the Tank watch to create a new watch shape. The two parallel brancards are an established signature of the Tank watch. Formal research made it possible to move from a square (the dial) to a rectangle (the bracelet). The secret lies in the balance between the lines and shapes, the volume and harmony that emanate from the design and lend the Tank its remarkable elegance.

In 1904, Louis Cartier granted the aviator Alberto Santos-Dumont's wish: to be able to tell the time while flying, without having to let go of the controls to check his pocket watch. Cartier broke ground by imagining a square watch in a world dominated by round ones, whose screws, traditionally hidden in watchmaking, are made visible on the bezel. Rounded edges, symmetrical bevels and curving horns that converge towards the bracelet. Original precision allows Cartier to rework the proportions of the Santos watch according to the times.

First created in the 1980s, the Panthère watch is the ultimate jewellery watch. Instantly recognisable, the Panthère watch takes its name from the bracelet which exudes lusty sensuality and the fluidity of its links which coil seductively around the wrist. An iconic style that layers elegance upon elegance: the dainty square case with rounded corners, the refined visible rivets and the dial displaying all of Cartier's watchmaking codes.

Created in 2007 from a new vision of roundness, the Ballon Bleu case is domed on both the front and back. Its emblematic crown cap, which is incorporated into the case, makes it instantly recognisable. With this watch, Cartier pays homage to the great tradition of watchmaking and brings a new twist to its codes by transforming the “rail-track”, introducing the blue bubble, and adding the optical illusion of the domed sapphire crystal.

Essentially, it is a single initial that has been duplicated. A single initial belonging to that of a Parisian family, who, from the early 20 th century onwards, went beyond the boundaries of design, under the impetus of three jeweller brothers and their father. Two intertwining Cs, these stylised letters representing Cartier are stamped on the Maison's watch cases.

Black, graphic and sloping, the Roman numerals on the case radiate out from the central axis, reinforcing the purity of the line present on Cartier watches.

The dials feature a "rail-track": a double line with a minute scale. Its design resembles the tracks of a railway line. Louis Cartier is to thank for this highly unique design.

The blue hands are the product of a watchmaking tradition found in the Swiss mountains. It’s here, whilst seeking to find a way to prevent watch hands (which at that time were not water resistant) from corroding under the tough climate conditions, where the watchmakers invented the process of bluing. This expertise has since been preserved and carried out by Cartier in a unique way: the hands are placed in kilns that are heated to over 300° for a duration of time which is calculated down to the second in order to obtain the iconic blue colour of the Cartier hands.
Producing these hands requires over 20 different procedures and over 10 different techniques such as hammering, cutting and polishing. Each second, minute and hour hand is selected and paired so that the hands placed on each watch are the exact same blue colour.

Cartier winding crowns are set with either a sapphire cabochon or a blue spinel depending on the model. They bridge the gap between jewellery and watchmaking.

Cartier's winding mechanism is adorned with a seven- or eight-sided beaded crown depending on the iconic style of the Cartier timepiece.

Engraved on the dial, the Cartier guilloché decorates the watches with a sunray motif. This decorative technique first appeared in the history of Cartier jewellery at the start of the 20th century. It consists of engraving fine lines on the plate of the dial to form different motifs such as waves or sunrays.

The Cartier signature is subtly placed at an angle in one of the Roman numerals on the dial.
