Un like ordinary w inding wat ches , automatic wat ches have no " tail ho ok " and are not hung on the inner wall of the strip ed box .
The ta il of the w rist of the automatic watch has a " sub w rist , " which is integ rated with the w rist by electric al spot weld ing .
In the free state , the zen mai is S - s hap ed , and the de formation direction of the " sub - zen mai " is oppos ite to this , and has anti - ex pansion .
Its wid th is slight ly nar ro wer than that of Zen mai , and its thi ck ness is about 1.5 times that of Zen mai , and its length can almost go around the car tr idge .
When the c ran ks haft ent ers the cr ate , the " se cond ary c ran ks haft " cre ates ex pan sive fric tion against the inner wall of the cr ate , and when the c ran ks haft is fully tigh tened , it s lides .
There are two indicat ors of the full string moment and the slip moment of the automatic watch , and if the slip moment of the automatic watch is not greater than the full string moment , then the full string moment of the automatic watch cannot be ens ured .
If the moment is too large , it is easy to appear " s wing " in the watch , and the up per string gear is also easy to be dam aged .
If it is too small , it will not be long enough to keep walking , and it will be easy to stop the c lock .
The w rist watch has a fric tion release mechan ism by two elas tic f itting of the split wheel and the automatic z eng , the hand z eng for the automatic watch is forever " up dis sat is fied , " once the up - str ing moment is greater than the slip moment of the z eng , the " sub - z eng " will slip with the wall of the z eng box and release .
The " sub - Z en mai " o iling insist ence , using vis co us gre ase oil or black mol yb den um dis ul f ide , strict ly control the oil volume , and under normal circumstances , the Z en mai box should not be opened .
