Overwinding a Seamaster? (2531.80 / 1120 cal)

I posted some days ago regarding my suddenly-stopped Seamaster. I took it to my AD, and before agreeing to order a replacement from one of their stores (I was lucky -- they only had one left in stock in the entire country, and Omega no longer ships them!), they insisted on having their watchmaker "take a look."

The salesperson today told me that the watchmaker determined that the watch stopped running because the gears became bound as a result of overwinding. I did not pursue the point because the next sentence out of her mouth was that they ordered the sole remaining Seamaster in their inventory and that I would be able to pick it up Friday or Monday.

However, the "watchmaker's" relayed message got me thinking. Aren't the Seamasters protected from overwinding by a ratchet mechanism of some sort? I remember reading this on the FAQ here, if not also in the manual.

Moreover, even if it were possible, I certainly couldn't have overwound the watch manually, as I had only wound it manually twice: 10 turns upon purchase, and another 10 turns about a week later. The week stopped a full week after my second "winding."

Granted, I spent a few hours in the morning of the day that it stopped running errands, so it would have been self-winding continuously, but even if a self-winder did not possess a mechanism to prevent manual overwinding (and I doubt this is true), it would certainly have to have such a mechanism to prevent overwinding as a result of wrist motion, right? That's something the wearer really has no control over.

In the end, maybe the "watchmaker" didn't know what he was talking about, maybe the message was relayed incorrectly.....or MAYBE we found exactly what went wrong with my watch. Maybe the anti-overwinding mechanism malfunctioned. But I would imagine that would lead to the mainspring breaking (I have no indication that this happened), and not the gears "binding up."

In any event, I'm just happy that I'm getting a new Seamaster. But I thought I would throw this question out: can a Seamaster be overwound?
