IWCのインスタグラム(iwcwatches) - 4月25日 22時00分

As part of the type testing process, #IWCWatches puts the movement with all its sub-assemblies through its paces and simulate ten years of wear and tear. Among other things, we turn the rotor several million times or check the workings of the chronograph over thousands of cycles. To finish off, we put the balance and escapement through a series of strenuous tests. In an accelerated wear test, we carry 2.5 billion vibrations.
