Without it, you couldn\u2019t keep time on the go, let alone accurately. The technology was created nearly four hundred years ago and went largely unchanged until recently. Now that <a href=\"https:\/\/www.bobswatches.com\/luxury-watches\/\">luxury watches<\/a> are starting to play around with hairsprings &#8211; from finding new materials to working on their production in house &#8211; we\u2019re starting to hear, and see, more about this imperative watch component.

Either way, it\u2019s a flat coiled spring, usually made of metal, that\u2019s attached to the balance wheel. The hairspring causes the balance wheel to oscillate and controls how fast, and thus keeping time accurately. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Created in 1675 and credited to the work of Christian Huygens, the hairspring was, and remains, revolutionary in watchmaking. You can even say it\u2019s responsible for taking the watch mainstream &#8211; as it made early pocket watches more portable, reliable and affordable objects to own.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-35942 size-full\" title=\"Vintage Rolex Explorer Movement\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Movement-Vintage-Rolex-Explorer-1016-2.jpg\" alt=\"Watch Movement Hairspring\" width=\"1000\" height=\"675\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Movement-Vintage-Rolex-Explorer-1016-2.jpg 1000w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Movement-Vintage-Rolex-Explorer-1016-2-300x203.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Movement-Vintage-Rolex-Explorer-1016-2-768x518.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/Movement-Vintage-Rolex-Explorer-1016-2-563x380.jpg 563w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>\n<h2><b>So, how does the hairspring work?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Hairsprings make sure that the balance moves at a steady rate. When the hairspring coils and uncoils, it propels the balance wheel and each swing of the balance then allows the gear train to move forward in a set amount &#8211; which is translated into time by the rest of the movement.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Practically, it works similarly to the pendulum of a clock, but is portable and durable as it moves around on your wrist. In fact, over the course of a year, an average hairspring will oscillate 500 million times. Yes, you read that right. That means this component has to be extremely durable &#8211; it also has to be resistant to magnetic fields and temperature changes &#8211; two things that can disrupt the rate that it compresses and decompresses. And so with these challenges in mind, a select few have taken on the challenge of redesigning the hairsprings used in their watches.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-8072 size-full\" title=\"Vintage Rolex Daytona Hairspring\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2016\/02\/vintage-daytona-paul-newman-6239-movement.jpg\" alt=\"Vintage Rolex Hairspring\" width=\"800\" height=\"523\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2016\/02\/vintage-daytona-paul-newman-6239-movement.jpg 800w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2016\/02\/vintage-daytona-paul-newman-6239-movement-300x196.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2016\/02\/vintage-daytona-paul-newman-6239-movement-768x502.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>\n<h2><b>What companies are working on hairspring innovation?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">There are a variety of companies who are now building their own hairsprings in order to get out from under the heel of a select few manufacturing titans. These companies are producing and distributing their hairsprings to other watchmakers, but what we\u2019re most interested in are the handful of manufacturers who are innovating new designs with new materials in-house.

But being Rolex, they weren\u2019t going to just take on production, they were going to create something new. That\u2019s when we were introduced to Parachrom, an exclusive alloy of niobium and zirconium used to make their patented hairspring. The coiled-alloy is of course resistant to magnetic fields as well as temperature and pressure changes, but in-house innovation made it \u201810 times more accurate\u2019 than a traditional hairspring when exposed to shocks. It was also upgraded with a blue-hue oxide layer finish in 2005 to reinforce its long term stability.\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-35446 size-full\" title=\"Omega Seamaster Planet Ocean Movement\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/07\/Omega_600M_5D3_5091-Edit-copy.jpg\" alt=\"Omega Hairspring\" width=\"1440\" height=\"960\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/07\/Omega_600M_5D3_5091-Edit-copy.jpg 1440w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/07\/Omega_600M_5D3_5091-Edit-copy-300x200.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/07\/Omega_600M_5D3_5091-Edit-copy-768x512.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/07\/Omega_600M_5D3_5091-Edit-copy-1024x683.jpg 1024w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/07\/Omega_600M_5D3_5091-Edit-copy-570x380.jpg 570w\" sizes=\"(max-width: 1440px) 100vw, 1440px\" \/><\/p>\n<h3><b>Swatch Group, Rolex and Patek Philippe &#8211; Silicon Hairspring Project<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">What\u2019s better than one of the greatest watchmakers coming up with a new hairspring solution? The three top watchmakers joining forces to do so, of course. All-stars Swatch Group, Rolex, and Patek Philippe got together to work on a silicon hairspring in the early 2000\u2019s in collaboration with the Suisse d\u2019Electronique et de Microtechnique. They quickly patented the technology and got into a legal squabble with Sigatec who was also working on this at the same time. It got settled with undisclosed terms.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-27958 size-full\" title=\"Patek Philippe Hairspring\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/02\/Patek-Phillippe_5D3_5251-Edit.jpeg\" alt=\"Patek Philippe Hairspring\" width=\"1440\" height=\"960\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/02\/Patek-Phillippe_5D3_5251-Edit.jpeg 1440w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/02\/Patek-Phillippe_5D3_5251-Edit-300x200.jpeg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/02\/Patek-Phillippe_5D3_5251-Edit-768x512.jpeg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/02\/Patek-Phillippe_5D3_5251-Edit-1024x683.jpeg 1024w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/02\/Patek-Phillippe_5D3_5251-Edit-570x380.jpeg 570w\" sizes=\"(max-width: 1440px) 100vw, 1440px\" \/><\/p>\n<p><span style=\"font-weight: 400;\">But what came out of the joint-effort were three different silicon hairsprings from the world\u2019s most prestigious watch manufacturers. But why silicon? Well, it was kind of the natural next step for hairsprings as it\u2019s incredibly light, durable, anti-magnetic, and can withstand both temperature changes and pressure changes with ease. The problem is it\u2019s hard to work with, so it really did require a big effort. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Patek Philippe unveiled their Spiromax\u00a9 hairspring in 2006, and Swatch\u2019s Breguet released their own silicon balance spring that same year. The Spiromax hairspring has been improved over the years, now holding several patents for its geometry and the addition of an inner boss making it highly accurate. And it took them a bit longer, but in 2014 Rolex finally unveiled their own silicon composite version, the Syloxi\u00a9 hairspring, which features an entirely new attachment to the balance staff.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-5135 size-full\" title=\"Vintage Rolex Hairspring\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2014\/06\/movement-vintage-datejust-reference-1500.jpg\" alt=\"Rolex Hairspring\" width=\"1000\" height=\"667\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2014\/06\/movement-vintage-datejust-reference-1500.jpg 1000w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2014\/06\/movement-vintage-datejust-reference-1500-300x200.jpg 300w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>\n<h3><b>Zenith &amp; Tag Heuer \u2014 Carbon Composite Hairsprings<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Carbon composites were another clear choice for new a hairspring material due to its durability and extreme resistance to magnetic fields and temperature variations. In 2017, two big players pushed forward with their own variations of the material &#8211; Zenith unveiling their new Carbon-Matrix Carbon hairspring strengthened with carbon nanotubes alongside the release of their Defy 21. Using a complex series of chemical baths and reactions, they were able to grow the carbon composite at the molecular level on top of a silicium wafer instead of traditional etching methods. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Around the same time, TAG Heuer released their carbon-composite hairspring, the Isograph. TAG Heuer leveraged the freedom of design this material lends to really customize the hairspring, creating a spring that allowed for \u2018perfect concentric oscillations.\u2019 Plus, the carbon composite\u2019s low density makes it lighter and more shock resistant. So much so, they claim it withstood both metal and silicon hairsprings when tested up to 5G. <\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-35943 size-full\" title=\"Rolex Parachrom Hairspring\" src=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/e42eb0ca-7d3a-4ee7-ad66-686e6e6796bb.jpg\" alt=\"Parachrom Hairspring\" width=\"1665\" height=\"1097\" srcset=\"https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/e42eb0ca-7d3a-4ee7-ad66-686e6e6796bb.jpg 1665w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/e42eb0ca-7d3a-4ee7-ad66-686e6e6796bb-300x198.jpg 300w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/e42eb0ca-7d3a-4ee7-ad66-686e6e6796bb-768x506.jpg 768w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/e42eb0ca-7d3a-4ee7-ad66-686e6e6796bb-1024x675.jpg 1024w, https:\/\/www.bobswatches.com\/rolex-blog\/wp-content\/uploads\/2019\/08\/e42eb0ca-7d3a-4ee7-ad66-686e6e6796bb-577x380.jpg 577w\" sizes=\"(max-width: 1665px) 100vw, 1665px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The hairspring is the beating heart of your watch.
