Tudor (formerly Tudor) was born in the 1930s as a Rolex diffusion brand. The name comes from the Tudor dynasty, an English royal family, and it gained popularity in the UK before expanding to the world. Its general-purpose movements keep prices down, while its unique designs, such as snowflake hands and bold colors, and its robust cases ensure reliability. In recent years, it has achieved COSC-certified accuracy with its in-house MT movements, and has developed a diverse collection of watches, including the Black Bay and Pelagos. It combines Rolex-style quality control with an adventurous style, and is popular as an affordable luxury practical watch. Its investment value is also on the rise, and reissued models are attracting fans.
