Not Peltier.
Might not even be a Watermelon. If it's a newer MK patch, it doesn't qualify for the name.
Edit: I rushed to the link so fast that I didn't see your comment on the date. -- to me the pattern did seem more recent.
Edit #2: Didn't seem totally standard but closer to the Color 1 - Color 2 - Color 1 model than to the classic MK Patch and Ribbon pattern. Not sure what to make of the base glass. Been awhile since I fished out my modern MK patches. Suppose I should've done that before replying, or at least before the 2nd edit. *sheepish*
