    Well said Bro TheKing... Watches with complications are usually more time consuming to reset!

    But one point to note though, no matter what the turn & rest timings are, its VERY IMPORTANT to know the motor's RPM too. Do see my calculation given previously in this thread for TPD.

    Just to have your example of a 1hr rotating and 3hr rest...

    If the motor turns at 8rpm, then...
    1hr would give 480turns (in that hour)
    Now, if it goes on the whole day, then the TPD would be 1440/240 x 480 = 2880TPD

    Whereas, if the motor turns at 2rpm, then...
    1hr would result in 120turns (for that hour)
    Rotating the whole day, the TPD would achieve 1440/240 x 120 = 720TPD

    These are some 'secrets' that a good winder manufacturer controls the Turns per Day!

    Could I use a timer for brand ABC and run it for 6 hours per day, so that TPD can reduce to 800? ....Provided the winder runs on AC, of course.
    U also have to set the timer to do 1 hr on and 3 hr off cycles to allow the mainspring to unwind than to be continuously rotated.

    Also watches with moonphase should be kept wound, cos resetting the moonphase can be a pain.

    with the recent discussion on winder. i have attached the links to 2 articles which is easy to read with some technical details.

    Article on Winder part I
    Article on Winder part II

    A friend of mine had a 19 year DateJust which was left on and off to wind. She called me one day for help, (thought was her notebook problem). Went to her place and she point her watch on her bedside table and told me that it wouldn't move no matter how she tries to wind the watch. I had to hit the side of the watch against my palm and it begins to move again. It is quite troublesome if one does that. I later brought the watch to a friend in China Square and had the watch service and the technician opened the watch, the lubricant oil tried up which locks all mechanism.

    To me I would try to wind not too full if you are rushing for time, and have it moved as what I do understand is that the heartbeat of the watch will get slower (or not completely swing from left to right end to end) and that will affect your watch accuracy in long run.

    for now, if my watch stop. i just manual wind it, then wear it and off i go. if i dun wear it, i just leave it alone and let it stop.

    now my question is, will winding it only when need to be use do damage to the watch? i dun mind spending a few mins doing some winding and adjustment.

    to me a good winder is one that winds the watch enough to keep power reserve. not one when you buy and then buy another timer to regulate the power.

    this is silly, can you image the watch winder selling you the winder say, here you go, set the timer as well to control the TPD.

    it is in other telling customers (potential included) that my winder is 'faulty'.

    Yes bro, you are right.

    For the benefit to all... calculation is as follow:-

    Winder turns 5 min @ 9rpm giving 45 turns
    The winding sequence adds up to (5min CW + 15min Pause) 20min
    For 360 min (6hrs), 360 divide by 20 min = 18 repetitions
    45 turns x 18 reps = 810TPD

    Mathematically, we get 810 but in actual case, it'll depend on the weight of the watch, the tilt angle, weight & construction of turntable, etc...

    Quick thinking bro!

    In the 1st setting the winder turns clockwise for 5 minutes and then pauses 15 minutes. It will repeat for 24 hours (1440 minutes)… until you turn-off the mains.

    - Motor turns 9 times in one minute, thus in 5 minutes it will turn 45 times.
    - One winding sequence equals (5 + 15 minutes =) 20 minutes.
    - In a day (1440 minutes), there’ll be 1440 divide by 20 minutes = 72 sequences; this means that the (5 minutes-15 minutes) sequence will be repeated for 72 times.
    - Multiple 45 by 72 = 3240 TPD; this means your watch will turn 3,240 times in a clockwise direction.

    Hi all. I'm a newbie and this is my first post....
    Regarding brand ABC winder with 3240 TPD, could I use a timer at the power socket to run it for 6 hours per day to bring down the TPD to 800?
    Provided the winder runs on AC, of course.

    i would if you have a perpetual or annual calendar watch, then winder is probably a must because to set the watch after it has stopped can be daunting task for some.

    also if you have more than say 4 watches to rotate, it would make sense to get a winder out of convenience.

    There are two schools of thought for watch winders. Some find it necessary (esp those who own many automatic watches & are lazy to wind them); others, not so. To me, I need to rest my watches after some period of usage so I am in the latter camp. Unless of course, I have too many automatic watches to have to rotate, then I may get one in future.

    good enough is always subjective.

    to me
    1. only 1 watch on 1 rotor
    2. ability to set TPD and direction for each rotor
    3. warranty on winder (on parts including adapter)
