Auto Rolex needs a shake to start even with hand winding

[coolerfiend]

Hi,

I recently acquired a Rolex Explorer 114270 from 2005. Service history unknown. When the watch comes to a stop, winding the crown will not cause it to start up, it needs a shake to get the second hand moving. However, I did a test where I started with it fully stopped and out of charge, wound the crown 60 times and then shook the watch for 5 seconds, then set it down, and it did run for the 48 hours of full power reserve. So, I know the hand winding does in fact charge the mainspring. It's jsut that hand winding alone will not cause the second hand to start running.

Anything to worry about here?

Thanks!
