George Daniels, CBE, FBHI, FSA, AHCI was an English horologist who was considered by some to be one of the best in the world in the field of luxury mechanical watches and timepieces during his lifetime. He was a watchmaker who all but completely built 23 pocket watches and 2 wrist watches as well as a number of clocks all by hand. Daniels commented often that "a watch has historic, intellectual, technical, aesthetic, useful and amusing qualities" and he sought to make watches that did each of these things while consistently improving on the technical and horological aspects of each watch he made. As at December 2022, George Daniels watches only sat behind Patek and Rolex watches by reference to value and number of watches sold, with 6 watches achieving prices in excess of USD$1.5 million. This makes George Daniels watches the first independently made watches to achieve this result.

A true contemporary diver's watch is in accordance with the ISO 6425 standard, which defines test standards and features for watches suitable for diving with underwater breathing apparatus in depths of 100 m (330 ft) or more. Watches conforming to ISO 6425 are marked with the word DIVER'S to distinguish ISO 6425 conformant diving watches from watches that might not be suitable for actual scuba diving.
