    Could hacking damage a movement?

    I noticed a while ago that a few watches in shop windows have their crowns pulled out in the Ďtime settingí, hacked position. I always thought it odd but thinking about it, it makes sense to put the break on an auto movement when the watch goes in the box, rather than letting it discharge the power reserve, then having to hand wind a few turns when it goes back on (which Iím told one should avoid in autos).

    Question is: does leaving the watch hacked cause damage to a partially wound mainspring which is being held under tension?

    Iíve noticed a few sellers do this and it seems odd to me: why wouldnít the default be to keep the crown in its usual position, the case sealed and avoid the chance of catching the crown and stressing the stem by mistake?

    IANAWM but given normal running involves main springs unwinding and winding, it seems unnecessary to worry about it.

    I look forward to hearing from the experts.

    Not good stop a spring under tension for weeks better let it run out.

    Doesn't make sense on an automatic watch, just let it run down and rewind next time you wear it.

    I can understand pulling the crown out to take pictures etc.

    I think it's more common with Quartz watches as that can save the battery life.

    i suspect it's because they are told to do it with quartz watches to save battery and don't know the difference..

    I never get why people photograph watches with the crown out. It just looks awful, which kind of defeats the point. Just set the time and take the photo, easy!

    Ha you know I bet you're right. Sad state of most dealers.

    Itís typically done to display the watch in the preferred ten-past-ten handset orientation.

    Who told you that crown winding a depleted automatic is bad for the movement?

    As stated, in order to set and hold the hands at a certain position. Nothing worse than the hands obscuring dial details on a watch sales pitch or even worse a blurred photo. The crown out gives you time to take a few photos so you can pick the best.

    Some of the listers on SC should try it sometime

    I just remember reading it in a few places than hand winding a mechanical pits too much torque on the mechanism. It may be nonsense, theres a lot of here say in this hobby, after all!

    EDIT

    **that should have read hand-winding an auto**

    It's pretty common knowledge that the 2824 doesn't like regular hand winding:

    Although, I don't know why you'd need to hand-wind an automatic so often that it became a problem?

    Great observation.

    ...of course we are all assuming that the OP does know the difference, in which case I'll get my hat.

    Thanks for sharing this - there are so many contradictory "old wives tales" surrounding automatics that I'd not taken this one on board before.

    I hand-wind my small collection of dailies, well, daily - and this is something it seems I need to stop doing.

    Does anyone know if the same issues affect the closely-related Sellita SW200-series movements?

    And Valjoux 7750?

    Iím familiar with the fundamental difference between quartz and an automatic.

    My question relates more to whether itís better to leave the watch hacked when itís put away, so to avoid handwinding an auto, or whether this in itself may cause harm to the mainspring and thus itís better to allow the spring to discharge regardless.

    In the past Iíve bought cheap quartz that have a little spacer keeping the crown out that you have to remove before first use.
