What is a dive watch? Do only divers use dive watches? Are they practical for usage above sea-level? These are all confusing questions, but the answers are simpler than you may think. A dive watch is a watch that theInternational Organization for Standardization (ISO) has set apart for its adherence to certain standards, many of them relating to its ability to function underwater. However, the majority of people who wear dive watches (also known as diving watches or divers’ watches) never visit the seafloor. They’re perfectly practical for those of us who are not aquatically inclined, especially because they are waterproof and specifically designed to be visible in low lighting. Who couldn’t make use out of that?
