Watch In Focus - Cartier Ballon Bleu


The curved case gives the watch the first part of its name, the gently sloping sides puffing up the case to its famous voluptuous proportions


The double butterfly clasp blends the strap into one complete bracelet to keep the aesthetics clean and simple


The blue cabochon in the crown, a trademark of Cartier timepieces, lends its name to second half the watch's title


The crystal follows the curve of the case perfectly, completing the illusion of being an inflated ballon


The guilloched dial, roman numerals and blued hands are typical Cartier; as is the hidden signature at seven

Cartier Ballon Bleu

Posted 28th Nov 2011

Cartier has always been pushing boundaries when it comes to watch style and design. Although other manufacturers have made their name by producing wonderfully exquisite and ornate movements, Cartier prefers to stun its audiences by making timepieces and accessories that have original visual appeal. You know when you’re looking at a Cartier.

Rectangular watches are a staple diet for Cartier, the Tank and the Santos being two good examples, but that isn’t the limits of Cartier’s imagination when it comes to watch design. The Pasha, originally designed as a water-proof watch for the Pasha of Marrakech in 1933, has a grille covering the crystal and a chain securing the screw down crown protector – details that would otherwise seem out of place, yet have proven very popular.

The Santos drew men away from their pocket watches and got them interested in wrist worn watches, previously considered to be a woman’s accessory. Design and fashion is something Cartier is very qualified to make decisions about, and the Ballon Bleu, launched in 2006, is evidence of that.

The name comes from the two most prominent details on the watch, the blue synthetic sapphire ‘cabochon’ mounted in the crown, and the swollen, spherical shape to the case is reminiscent of a balloon. The cabochon is a trademark detail of Cartier’s but the Ballon Bleu’s case shape is entirely unique. Its three-dimensional form is almost impossible to gauge via images alone, as is the incredible quality that allows the shape to be made.

Impressively, the case curves at a graduating rate that blends seamlessly into the domed crystal, really emphasising that balloon shape whilst also maintaining a smooth, simple appearance. The balloon ‘knot’ is formed of a continuing loop around the crown, which also cuts into the crystal and is mirrored on the dial. The dial itself is classic Cartier, silver guilloche, small black hands and Roman numerals. The simplicity makes the watch – there is no doubt that the right balance has been achieved to make the watch both easy to use and good to look at.

Cartier hasn’t stopped there with the Ballon Bleu. The 2011 ‘Extra-Flat’ watch is large at 46mm, but is also, as the name suggests, very thin. It still retains some of the original curve, but has obviously been deflated slightly to fit within the new svelte proportions. More excitingly for 2011 was the prototype ‘ID One,’ a platform for demonstrating the future technology in horology. The case, made from ‘niobium-titanium,’ is hypo-allergenic and highly wear-resistant. More interesting though, is the ‘zerodur’ hairspring and the ‘carbon crystal’ balance wheel, escape wheel and lever. Zerodur is a glass-like ceramic material with high magnetic and temperature resistance, and carbon crystal is a very hard, also glass-like material that requires no lubrication.

What this means collectively is a watch that does not need regulation or adjustment at any point of its life – a completely maintenance-free watch. And this sums up Cartier nicely. They don’t do what people expect, but when they do, everybody pays attention.

    What is it with cartier of late? This ‘blue ball’ affair is an another example of an over complicated case construction, that smacks of finding a way to compensate for a fairly poor watch. They did it with the W7100037. It takes 16 (approx) screws to take the case down. And doesn’t even have a screw down crown! They seem to be becoming the JLC movement equivalent in the case department. The ball affair feels quite nice though, if you like that metrosexual slippery, smooth sort of thing. No names.
