Watch is generally measured in the amplitude of swing, Switzerland early AM201 and GD – 50 type that we have produced. It is the use of so-called “Angle method” to measure, so, before measurement must choose good watches being measured corresponding balance wheel Angle.
Watch the water after the following methods:
After 1, watches, such as wet by water, can use a few layers of toilet paper or easy to moisture absorption of the flannelette bag tight closely, about 15 centimeters in near 40 watts of light bulbs, bake for about 30 minutes, the water vapor in the Omega seamaster 300 can be moisture. Avoid by all means will watch Omega seamaster 300 near the fire baking directly, lest make Omega seamaster 300 thermal deformation.
2, the Omega seamaster 300 itself, pan out, anti wear on your wrist, water can be removed after two hours. If water is serious, immediately send best watch shop clean oil, remove moisture movement, in order to avoid rusting parts.
3, with granular silica gel with watches have water in a closed container, hours later, remove the watch, the water is all but disappear. This method simple and economic, accuracy and life of the Omega seamaster 300 are without any damage. Has water absorption after many times of silica gel, and can be dry for several hours under 120 ℃, water absorbing capacity of renewable, also can be used repeatedly.
Watch at the time of test swing with instruments, there are several important related indicators:
1, swing head: watches after 24 hours and go full string under the two states, respectively, measure the two surfaces (surface and bottom) and three vertical (next, turn left, and turn on), the five changes position of the swing, with compared with position, take the biggest difference as a swing. Swing head also watches an important index of the performance, also can reflect on and balance spring and its design and assembly quality, usually require drop below 50 degrees.
2, swing flat vertical difference: watches in the condition of full string, respectively, measure the two surfaces (surface and bottom) and three vertical (next, turn left, and turn on), the five changes position of the swing, with a watch on the surface of the plane position and compared several vertical position, get the biggest difference as a swing flat vertical difference. Swing flat vertical difference also watch the position error is an important indicator of performance, often require flat vertical difference below 50 degrees.
3, the lowest elevation 24 hours swing: watch in real 24 hours later, the vertical plane (generally choose the left position) the lowest swing is not less than 180 degrees. Watch in the case of high swing low than the swing when the performance is better, especially for a watch with calendar attachment, the requirement of minimum 24 hours facade swing is particularly important.
Watch is generally measured in the amplitude of swing, Switzerland early AM201 and GD – 50 type that we have produced. It is the use of so-called “Angle method” to measure, so, before measurement must choose good watches being measured corresponding balance wheel Angle. In the instrument were used to detect the watch, a complete test unit needs a correction Omega seamaster 300 meter and amplitude meter. Before the clock on the maintenance, I saw in the school Omega seamaster 300, amplitude meter only can be seen in a watch factory. Shows that it is generally only pay attention to watch how quickly the precision of the swing and precision are equally important and interrelated, the technical index of the swing is bad, divide the peace sign too poor watch, must also go bad. Especially in calibration balance wheel balance, adjust the position error, must want to refer to swing, swing the concept of demand higher theoretical level maintenance personnel of the clock.
