Valjoux 7750: The World’s Most Iconic Chronograph Movement

If you’re a lurker on watch websites and forums for a while now, then you definitely know that the movement is one of the most vital parts of a watch. In layman’s term, the movement pertains to the gears that make your watch tick. It’s like the engine that powers your timepiece. If you dig in a little deeper, you would notice that most watch enthusiasts are partial to the Valjoux 7750, also known as “the world’s greatest chronograph movement”. 

So, let’s find out below why the Valjoux 7750 is worthy of this title.

What is the Valjoux 7750?

The Valjoux 7750 is one of the most favoured chronograph movements in the timepiece industry. In fact, a lot of people claim that it is the best in its category. With that said, most famous brands nowadays use this movement to power their watches. A few of those brands include Hamilton, IWC, and even TAG Heuer.

What makes the Valjoux 7750 distinct is that it uses a three-plane cam system instead of the usual column wheel. This tweak resulted in a more responsive movement that can be produced easier compared to its column wheel counterpart. These advantages made it easier for manufacturers to use Valjoux 7750 in their watches.

Apart from the chronograph function, the Valjoux 7750 also boasts a hacking function. Modern Valjoux 7750 calibres also have 25 jewels and around 48 hours of power reserve. On top of that, it uses the Incabloc Shock Protection System to protect the calibre in case the user drops the watch or subjects it to physical shock.

Moreover, the Valjoux 7750 also plays a key role in the emergence of several other movements. Instead of recreating the wheel, a number of brands agreed to use this as a base for creating their own calibres. A few modifications include the GMT hands, improved power reserve, and different positions for the date window.
