Watch stops after wearing for a few hours - Rolex Submariner Oyster Watch for Men

Almost all automatic wristwatches made today have an 18-24 hour "power reserve" when fully wound. A 24 hour reserve is actually very, very good. I can't think of a modern self-winding wristwatch that has a 48-hour power reserve because that would require a super-long or much larger mainspring than would fit in a modern watch movement / case. There may be some hand-crafted or super-premium watches that can do this, but only a very select few.
Manual wind railroad pocket watches, which were some of the finest and most accurate mechanical watch movements ever made, generally had a 40-hour power reserve. That extra capacity was created by using a large mainspring to store the extra energy. These mainsprings could be used because of the much larger size of these watches, compared to modern wristwatches.
If you are concerned about keeping your watch ticking, even when you're not wearing it, you might want to look at a "watch winder"--basically, a small watch case that rotates the watch for you, keeping the automatic winding rotor moving and the watch ticking. In addition, sitting at a computer all day will wind your watch much less than walking and otherwise moving around. Even though you're wearing your watch, if you're not moving, you're not winding it.

A Rolex watch is automatic.It needs to be worn 8 hours per day to store enough power to run 36 hours off the wrist.Assuming that you are wearing the watch daily if it still stops there is a problem with the auto winding or mainspring.As a new watch it will be under the Rolex guarantee so return it to the place of purchase.If you dont have a guarantee contact www.rolexrepairs.co.uk for advice or a free estimate.

Two words: Wind it! When any self-winding (automatic) watch runs down from not wearing it you have to manually wind it to get it going again. Once you've done that the movement of your wrist will cause the self-winding rotor mechanism to keep it running as long as you are reasonably active and wear it everyday. Just wind it about 40 turns and you'll be good to go. Oris is a great watch company and you should enjoy it for many years.

normally automatic watch need to wear at least 8hrs in a day ,then it works for next 30hrs.if it stops or loosing time, it indicates that needs service with lubrication .

These watches are self winding (mechanical spring), so need to be worn (or gently oscillated) to wind them up.

The catalogue for this watch says it should run for 72 hours when fully wound.

Depending on when the watch was made, it could be that it needs a clean.

Try wearing it for a few days to see if it keeps going.

Hi
The watch needs a clean and service. Please take it to a watchmaker

You have to wind the watch till it is fully wound (significant resistance should be felt).
It doesn't matter how many times you wind it (1 or even 40) - what matters is the strength of the spring.
Do as follows:
At any time in the morning wind the watch up till you feel there is no more winding left (should be quite tough). Memorize the time you did it.
Leave the watch (or wear it) till it stops completely.
Count the hours your watch did work (from the time you wound it).
Now you know exact power reserve for your watch.
It is advised to wind the watch 2-3 hours before the power reserve is gone.

Rate me.
, please.

There can be hundereds of causes why your watch isn't working properly, so, I'll not name them.
One is clear- without help of skilled watchmaker your watch will NEVER work properly.
NOTE: It may sound very strange, but mechanical watches do NOT like to be left without job.
Next time you decide to leave mechanical watch aside for long time- do not forget to wind it up once in a 2-3 days even if you are not wearing it.
This will help to prolong watch movements life and keep timekeeping steady and accurate.

Your watch is an automatic watch which means it winds itself as long as you are wearing it. If you don't wear it for several days it will stop working. To solve this situation buy an automatic watch winder to keep your watch in while you are not wearing it and it will keep the correct time.
