At 109g on Squale's included strap, the Squale 50 Atmos Ocean Blasted 1521-026 wears perfectly on my 7-inch wrist. Its combination of curved lugs and light weight make for a very fuss-free wrist feel and, for my tastes, the proportions are perfect.
UTC is 24-hour time, which begins at 0:00 at midnight. 12:00 is noon, 13:00 is 1 p.m., 14:00 is 2 p.m. and so on until 23:59, which is 11:59 p.m. Time zones today are a certain number of hours or hours and minutes behind or ahead of UTC. UTC is also known as Zulu time in the world of aviation. When European Summer Time is not in effect, UTC matches the time zone of the United Kingdom.
UTC used to be called GMT (Greenwich Mean Time), after the Royal Observatory located in the Greenwich area of London. UTC is also sometimes called Z or Zulu time. A time may be written as e.g. 21:45Z with the Z indicating UTC. The Z is for zero, and Zulu is the two-way radio pronunciation of Z.
