Baume & Mercier (French pronunciation: [bɔm ˈe mer-sjej]) is a Swiss luxury watchmaker founded in 1830.

The Swiss watch manufacturer established a branch in London in 1851 under the name "Baume Brothers", which led to expansion throughout the British Empire.

By the late 19th century, the company had an international reputation, and its timepieces had set accuracy records and won a number of timekeeping competitions.

In 1919, Baume & Mercier was awarded the Geneva Seal, the highest international distinction of the time for watchmaking excellence.
