63 series marine watchDetailed product description：

structural characteristics
This series of instruments features magnetic electric shaft tips and bearing structures. An AC instrument is composed of a transistor rectifier circuit device attached to a DC meter, which consumes less power.
Due to the 250 degree deflection of the pointer and the use of a transparent organic glass cover, wide and clear readings can be obtained.
