Pl advise

Do we need to give automatic watch a shake after adjusting the time.

Mine need a shake after tightening the crown for the second hand to move again.

New to how automatic watch works? Just brought a pair of entry level rollies recently.

Thanks.

wind up first before shaking.

Mine is brand new Air King 114200.

As i don't wear the watch daily, the watch will stop moving after some time. So i will need to adjust to current time by losening the crown and tigtening the crown after that. But the second do not start ticking unless i give the watch a shake.
By the way may i know what does winding means? I thought the watch is self winding?

Thanks.

bro, self winding only if you wear it, else u need to wind it up before it will move again

cheers

try winding up a few revolutions before shaking. this is important for the engine reliability.
try avoiding shaking before the hand starts to tick

Hi thanks for the advice. Btw, may ii know how many rounds should i turn?
Is it clockwise, after i have loose the crown and there is "something" like the spring out effect? Before i start the winding process.

i noticed (for my case) new rolex will stop for the 1st one or two times (on a weekend) after wearing full 8 hours for 5 working days. my sub and my wife date also the same. then the time will start to be slower.. what i did was on weekends, i will wind for 40 rounds. After around 1 month, my sub can no need winding anymore and i js wear for 2 - 3 hrs on weekends, and the watch is still going strong and accurate after 2yrs 3months and still counting..

If you are not sure how to do it properly, you should bring it back to your AD and they will be glad to teach you. If your AD is good and experience, they will show you a few tricks. Good thing your new watch do not have day/date, if not you will have a few more thing to turn.
Seem like you need to do this exercise (screw out and in the crown) regularly, make sure you don't cross tread when screwing in the crown.

Sorry, this doesn't sound right to me. If in the factory when they test it and it can't hold a 50hrs reserve power. They should declare as defect and not sell it. I don't think there is a break in period. Correct me if I'm wrong.

could be higher viscosity of oil in new watches that were left on shelf for some time hence slower time and lower reserve
after run in for ~1month, the viscosity reduce to the 'normal level' and distributed to all parts of movement

You might be right. The watch must be seating for quite sometime in either a very hot or very cold display shelves that cause the viscosity to change.

Learn something new any good advise for watch storage in humid conditions in SG?

[TanWL]

I read somewhere oil viscosity is higher at low temperatures and lower at high temperatures, means with heat, oil flows easier, compared to if its kept in lower temperature

In showrooms conditions, the temperature is low due to aircon, worse still, if the watch is kept on display shelf and not wind-up regularly, the movement does not get the regular 'exercise' necessary to keep the oil well-distributed

Recommended is one full winding every 4-6weeks to let the movement run
I don't think AD SEs got time to wind up so many watches in the showrooms

Usually the viscosity of oil is specify to a certain range of temperature. Example for cars is SG we use 10w-40 for our engine oil, 10 for the low temp and 40 for high temp. It guaranty that the oil will not clot up within this temperature. So if the oil used in watches is chosen correctly we shouldn't have any problem with our air-con rooms and tropical temperature, so winding now and then should not be necessary due to the oil propriety.
Losing power reserve or slowing down could be the oil is drying up or the propriety of the oil is degrading due to aging.
