So when the house introduced a perfectly round watch in 2007, it was a real departure. Nearly two decades later, the Ballon Bleu de Cartier has become one of the most recognizable modern watches in the world, worn by men and women alike and found in almost every size and metal. If you are thinking about buying one, new or pre-owned, this Cartier Ballon Bleu buying guide covers its history, the sizes and movements, the materials and complications, and what to check before you buy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A Short History of the Ballon Bleu<\/h2>\n\n\n\n<p>Cartier unveiled the Ballon Bleu in 2007 at the Salon International de la Haute Horlogerie in Geneva, according to <a href=\"https:\/\/www.rebag.com\/thevault\/watches-101-the-cartier-ballon-bleu\/\" target=\"_blank\" rel=\"noopener\">Rebag<\/a>. The name means &#8220;blue balloon,&#8221; and it comes from the watch&#8217;s most famous detail: a blue cabochon set into the crown, which seems to float inside a protective metal arch on the side of the case (<a href=\"https:\/\/www.sothebys.com\/en\/articles\/the-complete-guide-to-the-cartier-ballon-bleu\" target=\"_blank\" rel=\"noopener\">Sotheby&#8217;s<\/a>). The rounded case was a clear contrast to the angular <a href=\"https:\/\/www.truefacet.com\/guide\/cartier-tank-buying-guide\/\" target=\"_blank\" rel=\"noopener\">Cartier Tank<\/a> and <a href=\"https:\/\/www.truefacet.com\/guide\/cartier-santos-buying-guide\/\" target=\"_blank\" rel=\"noopener\">Cartier Santos<\/a>, and its soft, pebble-like profile is a big part of why owners find it so comfortable.<\/p>\n\n\n\n<p>The design was quickly recognized. <a href=\"https:\/\/www.rebag.com\/thevault\/watches-101-the-cartier-ballon-bleu\/\" target=\"_blank\" rel=\"noopener\">Rebag<\/a> notes that it won &#8220;Watch of the Year&#8221; honors from Japanese GQ and from Germany&#8217;s Uhren-Magazin in 2009, and that Cartier released a limited edition in 2012 with a dial cut from a meteorite. Since then the collection has grown to include gem-set versions, skeleton and tourbillon models, and a long list of sizes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Signature Design Details<\/h2>\n\n\n\n<p>Every Ballon Bleu shares a few features that make it instantly recognizable. <a href=\"https:\/\/www.sothebys.com\/en\/articles\/the-complete-guide-to-the-cartier-ballon-bleu\" target=\"_blank\" rel=\"noopener\">Sotheby&#8217;s<\/a> lists the key ones:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>The round, domed case<\/strong>, with a curved crystal and caseback that give the watch its balloon-like volume.<\/li>\n\n<li><strong>The cabochon crown under an arch.<\/strong> The crown sits partly inside a guard that is part of the case itself. The blue stone is a synthetic spinel or a sapphire, depending on the model (<a href=\"https:\/\/www.rebag.com\/thevault\/watches-101-the-cartier-ballon-bleu\/\" target=\"_blank\" rel=\"noopener\">Rebag<\/a>).<\/li>\n\n<li><strong>Roman numerals<\/strong> that are subtly stretched near the edge of the dial to follow the case&#8217;s curve.<\/li>\n\n<li><strong>Guilloch\u00e9 dials<\/strong> on many references, usually in silver with a fine engine-turned pattern.<\/li>\n\n<li><strong>Blued steel sword-shaped hands<\/strong>, a classic Cartier touch.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Choosing Your Size<\/h2>\n\n\n\n<p>Size is the biggest decision with a Ballon Bleu, and the collection is unusually broad. The core sizes are 28 mm, 33 mm, 36 mm, 40 mm and 42 mm (<a href=\"https:\/\/precisionwatches.com\/new-watches\/cartier\/ballon-bleu-de-cartier\/\" target=\"_blank\" rel=\"noopener\">Precision Watches<\/a>), and <a href=\"https:\/\/www.swisswatchexpo.com\/thewatchclub\/2022\/01\/20\/cartier-ballon-bleu-a-closer-look\/\" target=\"_blank\" rel=\"noopener\">SwissWatchExpo<\/a> notes that Cartier added the 40 mm version in 2020 with an in-house automatic movement.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>28 mm<\/strong> is the smallest and most delicate, a jewelry-like size that is often quartz and frequently diamond-set.<\/li>\n\n<li><strong>33 mm<\/strong> is a popular mid-size that reads as discreet but substantial, and works on many wrists.<\/li>\n\n<li><strong>36 mm<\/strong> is the true unisex size, offered in both quartz and automatic versions.<\/li>\n\n<li><strong>40 mm and 42 mm<\/strong> are the larger, bolder sizes, typically automatic and most often chosen by men.<\/li>\n<\/ul>\n\n\n\n<p>One caution: the domed case wears differently from a flat watch of the same diameter. <a href=\"https:\/\/finewatchguide.com\/brands\/cartier\/ballon-bleu\" target=\"_blank\" rel=\"noopener\">Fine Watch Guide<\/a> points out that the larger Ballon Bleus are fairly thick, while the smaller ones are lighter and slimmer, so it is worth trying more than one size before you decide.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Quartz or Automatic?<\/h2>\n\n\n\n<p>Knowing what is inside tells you what kind of care the watch will need. Smaller sizes often use quartz movements, while the larger ones are usually self-winding (<a href=\"https:\/\/finewatchguide.com\/brands\/cartier\/ballon-bleu\" target=\"_blank\" rel=\"noopener\">Fine Watch Guide<\/a>). A quartz Ballon Bleu needs a battery change every few years, ideally with new gaskets and a water-resistance test. An automatic needs a full service every several years, and recent models with Cartier&#8217;s own movements are best serviced by Cartier (<a href=\"https:\/\/finewatchguide.com\/brands\/cartier\/ballon-bleu\" target=\"_blank\" rel=\"noopener\">Fine Watch Guide<\/a>).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Materials, Gem-Setting and Complications<\/h2>\n\n\n\n<p>The Ballon Bleu is made in stainless steel, yellow gold, rose gold and white gold, as well as two-tone steel and gold, and many versions add diamonds to the bezel, dial or case (<a href=\"https:\/\/www.sothebys.com\/en\/articles\/the-complete-guide-to-the-cartier-ballon-bleu\" target=\"_blank\" rel=\"noopener\">Sotheby&#8217;s<\/a>). Steel on a steel bracelet is the everyday choice, while gold on an alligator strap leans dressier. Women&#8217;s models often add mother-of-pearl dials and diamond accents.<\/p>\n\n\n\n<p>For collectors, Cartier has also used the Ballon Bleu as a platform for complications. <a href=\"https:\/\/www.sothebys.com\/en\/articles\/the-complete-guide-to-the-cartier-ballon-bleu\" target=\"_blank\" rel=\"noopener\">Sotheby&#8217;s<\/a> highlights chronograph, dual time and tourbillon models, with high jewelry and complicated pieces that can exceed $50,000, while entry-level models on the secondary market start much lower.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What to Check Before Buying Pre-Owned<\/h2>\n\n\n\n<p>Because the Ballon Bleu is so popular, it is also a frequent target for counterfeiters, and condition and paperwork matter more than rarity (<a href=\"https:\/\/finewatchguide.com\/brands\/cartier\/ballon-bleu\" target=\"_blank\" rel=\"noopener\">Fine Watch Guide<\/a>). Before you buy, check:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Box, papers and service history.<\/strong> A watch with its original box, Cartier papers and a recent service record is easier to own and easier to resell. The serial number on the caseback should match the paperwork.<\/li>\n\n<li><strong>The crown and its guard.<\/strong> Owners sometimes force the crown because it sits partly under the arch. Make sure it winds and sets smoothly, and that the cabochon is not chipped (<a href=\"https:\/\/finewatchguide.com\/brands\/cartier\/ballon-bleu\" target=\"_blank\" rel=\"noopener\">Fine Watch Guide<\/a>).<\/li>\n\n<li><strong>Polishing.<\/strong> Because the crown guard is part of the case, heavy polishing can blur its shape. Crisp edges are a good sign.<\/li>\n\n<li><strong>Diamonds.<\/strong> Cartier makes factory diamond versions, but aftermarket setting is common. Confirm whether any stones are original to the watch, since this affects value (<a href=\"https:\/\/finewatchguide.com\/brands\/cartier\/ballon-bleu\" target=\"_blank\" rel=\"noopener\">Fine Watch Guide<\/a>).<\/li>\n\n<li><strong>The dial and numerals.<\/strong> The printing should be sharp and the Roman numerals cleanly executed. Smudged or uneven printing deserves a closer look.<\/li>\n<\/ul>\n\n\n\n<p>For a deeper look at warning signs, read our guide on <a href=\"https:\/\/www.truefacet.com\/guide\/spot-fake-cartier-ballon-bleu-5-red-flags\/\" target=\"_blank\" rel=\"noopener\">how to spot a fake Cartier Ballon Bleu<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Caring for Your Ballon Bleu<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Wind and set the crown gently, gripping it carefully under the guard rather than forcing it.<\/li>\n\n<li>Treat water resistance with caution, especially on older or recently opened watches, and have the seals tested when the battery is changed or the watch is serviced.<\/li>\n\n<li>Ask for a light clean rather than a full refinish at service time, to keep the case and crown guard crisp.<\/li>\n\n<li>Store it in its box or a watch roll so the domed crystal does not knock against other pieces.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Shop the Cartier Ballon Bleu at TrueFacet<\/h2>\n\n\n\n<p>The Ballon Bleu&#8217;s appeal is easy to understand: a soft, round case, a famous blue crown and a size for almost every wrist.
