In the world of mechanical watches, there is a common conception (or rather misconception) that all brands produce their own movements. For obvious reasons, the brands themselves are largely responsible for perpetuating this idea. However, as with most things, it doesn’t quite align with reality. In fact, quite the opposite is true. A large number of brands outsource their movements in their entirety, either from a third-party, like Sellita or Vaucher or, if they are part of a larger group (e.g., the SWATCH Group or Richemont), they may borrow movements from their fellow members. Sometimes these movements are modified to suit that brand’s specific needs, both technical and aesthetic. Sometimes they are not. In reality, there are relatively few true watch manufacturers or, in other words, companies that are completely vertically integrated and capable of creating their own movements from scratch. There are a number of good reasons for this, but chief among them is the cost and expertise required. That’s why even some of the most well respected names in the industry have been known to use externally-sourced movements from time to time. Here are four examples that might surprise you.
