What Is an In-House Movement? 3 Reputable In-House Watch Movement Manufacturers

What is an in-house movement? Why do watch collectors highly value it? Which reputable in-house movement manufacturers are there? To better understand this topic, Rep Watches invites you to follow the article below. We will explain this term and suggest some reliable in-house movement watches.

What Is an In-House Movement?

An in-house movement is a mechanism produced, developed, and assembled exclusively by the brand that uses it, representing a commitment to high-quality standards. A movement acquired from an external company is not considered in-house. Brands owning in-house movements have all legal rights associated with it, including selling their in-house movements to third parties.

Types of In-House Movements Based on Production Method

Based on production methods, Rep Watches categorizes in-house movements into two types to clearly describe their differences:

  • Exclusive In-House Movements: Produced at a factory owned by the brand and only used by that brand (e.g., Moser, Rolex, Grand Seiko).
  • Non-Exclusive In-House Movements: Produced at a factory owned by the brand and used by third parties (e.g., most Seiko movements).
