First, check the appearance of parts Rado watches

Rado watches from the shell the appearance of the watch mirror, dial and second hand so check the hours. Trachoma and obvious case should be no scratches, angular symmetry; back cover and the shell of the rotary joint Department should closely; two watches ring the same distance with the case, install the ear hole Huang rear foot should be in case the location of center or favor, the depth of the hole due to ring easy to fall off the watch; watch mirror should be no defects and scratches, transparent light; 3 pin installed correctly, pin and needle, the watch should be between the mirror and dial the correct security clearance; dial and pointer coating finish is good, no scar, dial the full scale lines or luminous points; head and about 0.1-0.3mm between the case of the gap.

Second, check the sensitivity of Rado watches

Rado watches of the sensitivity of its balance is automatically swing flexibility. Inspection methods are:

(1) had not had any winding watch has stopped walking about gently shake, shake with the power to observe the second hand move around: if the second hand stopped moving around in a very short period of time, it indicates only watch the full-fat After the can all finish the article (ie, no torque Clockwork), high sensitivity; if the second hand to move around a long time, it indicates only full winding watch can not be completed all the post (that is winding also stored torque), the sensitivity is not high machine malfunction or watch

(2) to stop the move did not go to winding watches, and slowly turned his head to observe the second hand start: The rotation of the article to less second hand description of the earlier start of the watch the higher the sensitivity; the other hand, the sensitivity of low or watch machine has other faults. But pay attention to watch as gossamer Quickly stiffness than traditional frequency (18,000 cycles / hour) on the watch a little more than winding confidential to swing. High sensitivity of watches, on foot after a winding longer continue walking.

Third, check the Rado watches the spacing and location of the pointer

Gauge needles watch mirror, and three between the dial needle should remain between a certain distance, or create another watch grazing affect the normal operation of machine. Check dial needle through observation. Hour and minute hands of the location and interaction of normal checks whether the method is: the minute hand and hour hand appropriated for 3:00, 9:00, observe whether the two pins at right angles; Slide 6, the two are into straight needle; appropriated for 12 points whether the coincidence of the two needles.

Fourth, check Rado for sale on the article body

The normal watch section should be easy. Turning the head when the article first feel more loose, gradually more and more tightly on, when the rotating head can not move forward, the instructions on the winding has been completely filled and the article body working. If the rotation handle section head, the place "Cha  abnormal noise, or produce such phenomena as the top gear skid, it indicates a failure on the article body.

Fifth, check the watch dial Needle Needles should be flexible in the allocation of watches, reliable and uniform rotation pointer. Inspection should be focused on checking points of friction with the wheel and the center axle tightness. Needle in the dial, if not partial loose or tight feeling, shows the normal sub-wheel friction and fuel amount, whereas the allocation of needle mechanical failure.

If you buy a Rado replica , then you can follow the above method to check whether the condition of your watch to buy for themselves to judge whether it is good form.
