I purchased this particular Bond Seamaster new from an authorized dealer, and know it represents one of the latest production runs for this model. One subtle change I've noticed on this SMP from previous generations I've owned is on the case back. Omega has added a new, highly detailed engraving to the case back, the purpose of which I assume is to increase the difficulty of counterfeiting. Here's a picture of the case back - the new engraving is bottom right corner of the case back:
Now here's a close up of the engraving itself. As you can see, it's pretty complex. The Omega symbol is surrounded by a simulated three dimensional globe. Texturing has also been applied to the engraving, as is evident in the Omega symbol inside the globe. While not impossible to duplicate, I'm sure the tooling necessary to do so would further drive up the cost of producing a fake SMP - hopefully making it cost prohibitive to do so.
