This amazing watch features a radio - controlled timekeeping system. It can pick up signals from four global regions to adjust the time automatically, offering supreme convenience. It comes with a 1/1 second chronograph that can measure up to 60 minutes precisely, an aviator slide rule, and a world time function for 24 cities. It's a highly versatile pilot's watch with great functionality and practicality. The watch has a sleek black dial, sapphire crystal glass, and 200 - meter water resistance. Keep in mind that the radio - controlled function doesn't work in Australia as there are no transmitting stations in range. It only works in Europe, USA, China, and Japan. But you can still adjust the time manually. Check the instruction manual for more details. It has Calibre G1502, a chronograph, and belongs to the Promaster Land series. The case and bracelet are made of stainless steel with a push - button buckle. The case size is 45.9mm, and it has a sapphire crystal.
Using this watch is easy. For the radio - controlled timekeeping, just make sure you're in Europe, USA, China, or Japan where the transmitting stations are available. If you're in Australia or other areas without these stations, you can always adjust the time manually as described in the instruction manual. To use the chronograph, press the relevant buttons to start, stop, and reset the 1/1 second measurement up to 60 minutes. The aviator slide rule can be used for various calculations related to flight. The world time function allows you to quickly check the time in 24 different cities. When it comes to maintenance, keep the watch away from strong magnetic fields. Since it's 200 - meter water resistant, you can wear it while swimming, but avoid high - pressure water situations like deep - sea diving. Clean the watch regularly with a soft cloth to keep the sapphire crystal and black dial looking good.
