This men's round chronograph air force pilot watch is a great timepiece. To use it, simply wind the mechanical hand-wound movement regularly to keep it running. The stopwatch and chronograph functions are handy for timing events. The watch is water-resistant up to 3Bar, but don't wear it for long - term underwater activities. When it comes to maintenance, keep it away from magnetic fields as they can affect the movement. Clean the nylon band with a mild soap and water, and wipe the stainless - steel case with a soft cloth. Store it in the paper box when not in use to protect it from scratches.
