O.K. you're reading the manual to your new automatic wrist watch and you come across 28,800 pulsations per hour. Huh!? What!?! Why? Let CTWG break it down. The 28,800 are the oscillations made by the balance in the watch. The little pallet jewel (the red teeth you see snapping forward and back) is the source of energy, literally, from rotating energy to oscillation energy. This becomes a controlled way to let down power! Count up all of these small but powerful strikes (1.5 million p.s.i.) and there are your vibrations per hour. Typically faster is better, lighter is better. 18,000 was the old standard speed and 28,800 is the modern fast speed. Many other speeds are used but there it is! CTWG

Oh it sounds easy... and it is! Still, I know people in the watch business that still do not know how to set a G.M.T. watch. Follow these simple instructions, most G.M.T.'s function with two hour hands, so set one hour hand to the outward bezel of the watch. Next, set the hour hand used on the normal dial, (it typically moves independently to set the date and the time). There is is! You have set two time zones. Now CTWG, what about the scary 24-hour outward bezel “it is not americanized to our time system? Yes, it can be tough to subtract 12, but we must advance as a culture. Besides, the bezel almost always has a dark/light look to indicate day/night time (use this to your advantage). Happy setting CTWG
