Unidirectional or bi-directional winding

[spicediablo]

Is it possible to identify whether a watch is unidirectional or bi-directional winding just by moving it and listening to the winding? Sorry for a basic question....

i cant

sound also depends on case construction, some hardly hear rotor sound

by far i ever heard, bi-wind have no special sounds, but uni-wind you may heard the rotor have very soft clicking sounds when turning one direction

well maybe some uni-wind watch does not have sounds so i could be wrong

For me, I could hear the rotor spinning sound from my watch if I hold it right next to my ear and it only make sounds if it's spinned in a particular direction (for me, with the dial facing my ear and clockwise spinning direction) but not the other. I guess we could tell by that way. But I reckon it doesn't work for all watches.

geez...i thought all winding is clockwise only

For unidirectional winding, the correct winding direction is softer than the louder sound of the opposite side (which is not winding)

Depending on the movement type, usually there is a louder sound when its winding the mainspring.

Just check the Orbita watch winder website. There is almost all movement winding direction and TPD on their database.

Thanks. Just checked my Longines Master Collection triple date moonphase is clockwise at 800 turns/day...

For me, the typical movement that I mostly own is 2824-2( both 650 tpd), 2836-2( both 650 tpd) and 7750(clockwise 800 tpd) . Most  common movement, so the setup is pretty standard. Unless the in house movement might be have to read the manual before using the watch winder. You can also determined the winding direction by hearing the clicking  sound from the rotor when rotating the watches.
