Most watch brands don’t make their own movements. The best watch brands make their own movements (in-house movements), and even better brands make their own movements as well as cases, dials, and hands. Jaeger-LeCoultre has the ability to make most watch components in-house, not just movements. What this does is give them an immense level of control over quality, as well as a great level of flexibility when it comes to design and experimentation. For this reason Jaeger-LeCoultre is able to produce such a diverse range of timepieces, each with unique designs and often movements.
