Adelanta demasiado para haberlo movido tan poco, ¿no?, vamos, yo he probado con algunos relojes (Seiko Samurai, Stowa Antea, Hamilton Khaki y Mido Commander) y sólo uno ha variado un segundo (el Stowa), el resto como si nada, así que o no los he movido tan fuerte como en el video o ese Omega del video es muy sensible...

Vale chicos aquí va la explicación:

Conclusion and most feasible Explanation: Be careful how you sway/shake/wind your automatic watches! Do not shake them near the resonance frequency of the balance wheel. The resonance of the balance assortment is simply f = 1/2 bps (beats per second). I trust you will not damage the watch if you shake it so fast. The jolts on the escapement or watch mechanism are not as violent as e.g. when playing sports (tennis).
Obviously shaking the watch near its 1/2 bps resonance results in forces on the balance wheel that might advance the escape wheel two cycles instead of one. I have never noticed a loss from shaking, the watches always gained a couple of seconds. I noticed also that an almost unwound main spring helped showing this phenomenon.
Automatic watches without winding mechanism (like many Seikos featuring the Cal. 7S26 and many Orient movements) are best wound by swaying them in ca. 8 inch (20 cm) circles. Just think of swaying a glass of Cognac.
