Clicking sound from a Sub-C

[salty_snack]

So I've had my Sub-C for about two weeks now and have loved most every minute of it. I have noticed a clicking sound coming from the watch however and wanted to get some input.

First off... when winding the watch using the crown there are distinct clicks (15 clicks per revolution of the crown) which I am assuming is normal. (this occurs even with the mainspring unwound) My other watches make more of a buzzz.....buzzz sound where each turn of the crown corresponds to dozens of very small "clicks" but since this is my only Rolex at the moment I have nothing to compare too.

The sound in question occurs due to the automatic winding mechanism most likely. It occurs somewhere between 1 and 2 revolutions of the rotor and never in the same rotor position twice in a row. (for example... It will click with the rotor at 1 o'clock... the rotor will swing 360 degrees back to the 1 o'clock position and the clicking sound can be heard before the rotor makes it back around to the 1 o'clock position a second time, 720 degrees.

Because the clicking sound is nearly identical to the sound the watch makes while being wound by hand I don't believe the rotor is contacting the movement or case back and it is, in fact, just the winding mechanism.

Just wanted to know if anyone has had a similar experience and if it is a problem or normal for the 3135.
