White gold is finished with Rhodium and carries a white tone. Gold is softer and heavier than steel, and is a common material on dress watches.

Rose gold is gold alloyed with copper. Different brands use different shades of rose gold by changing the amount of copper in the gold.

Yellow gold is the classic gold we are all familiar with. Gold watches are typically 18kt, which means that the gold is 75% pure.

Titanium is a very lightweight metal that is also quite strong. Titanium watches are well-suited for all-day wear due to their light weight.

One of the most durable metals used in watchmaking, and one of the heaviest too. Famous by the Platinum Rolex Day-Date and Daytona, and many prestigious dress pieces.

Ceramic is incredibly lightweight and scratch-resistant, but prone to shatter if dropped.

Two-Tone refers to a mix of two materials, such as gold and stainless steel, or platinum and stainless steel.
