Blood In The Water, Water In Its Blood: A Brief History of Squale. Any history of the dive watch would be incomplete without a thorough look at Squale. But despite its illustrious history, this small Swiss brand is still largely unknown to all but the most hardcore dive watch nerds.
The official abbreviation for Coordinated Universal Time is UTC. This abbreviation arose from a desire by the International Telecommunication Union and the International Astronomical Union to use the same abbreviation in all languages.
The UTC is based on an atomic clock to which adjustments of a second (called a leap second) are sometimes made to allow for variations in the solar cycle. Coordinated Universal Time is expressed using a 24-hour clock but can be converted into a 12-hour clock (AM and PM). UTC is used in plane and ship navigation, where it also sometimes known as Zulu. UTC uses the Gregorian calendar.
