Rolex might be the most recognizable watch companies in the world and flatly a world-famous brand. Even still, there are a few things people might not know about the watch giant and its iconic green and crown logo.

Here are a few of those fun facts about Rolex.

Almost all the parts of a Rolex watch are made in-house and the completed product can take a whole year to make. The watches are all handmade and hand-tested.

Rolex HQ is very secure.
