I appreciate the compliment, but I don't think anybody is an expert on ALL things Pulsar...there are still too many unknowns (I would agree that I know more than most, but even I am still learning); the P1 just happens to be of particular interest to me (my favorite, actually!).
So, to the questions at hand...
1. This is not No. 280's first appearance on eBay...it sold for just over US$10,000 not long ago (along with No. 650, which, while not working, did have its' original boxes, which made up the difference in value). That was reasonable then, and it is still reasonable now. This was one of Archer McClean's P1s, and it is in good, original, condition (the first picture in the auction, of a P1 on a stand, is of another watch, and should be removed; in my opinion, this is deceptive, as it is NOT the actual item for sale). Certainly, the current asking price (like the $27,500 18K Calculator), is beyond all reason and completely detached from the reality of the current market (don't misunderstand me...some day these watches WILL sell for these kind of prices, but that is many, many, years down the road); actually, the last P1 listed on eBay for $25K I bought for less than $7500, and it had its' original inner and outer boxes, as well. Such a "complete package", with boxes, manual, spare magnet, etc, might go more into the $15K range, to the right buyer (there are only 7 or 8 such complete watches). As for serviceability, the majority of known P1s still seem to be in working condition after 40 years, and can be repaired by grafting in a 201-1 circuit board from an early P2 (I've done a couple of these...about a $1K fix, but the factory service on a high-end Rolex or Patek will run about the same, so that does not seem overly expensive to me, given the major historical significance of the watch, and the added value of being restored to original working condition; such a proper restoration could in no way diminish its' collectible value). My primary dissatisfaction with the current auction is that it appears to be a pretty shameless attempt to make a quick buck (I bought the first of my 9 P1s 8 1/2 years ago, and none will be for sale any time soon). I extract a scrap of solace from the fact that, short of finding some fool with a wheelbarrow full of lottery money to throw around, this watch will remain where it is, until the price drops back into the real world (I suspect all the offers have been in the $10K range, and there would be no profit in selling at that price). I think it's also important to remember that the great majority of the value is embodied in the fact that this is a P1, the first watch of its' kind, and its' historical significance, rather than the simple value of the material used to make it.
2. The awful pictures make it impossible to get an accurate count of the bracelet links, but, assuming there are 20 (most known P1s seem to have 18-20 links), that gives a gross gold alloy weight of approximately 130 grams, or 4.18ozT, giving 3.135ozT of pure gold content. With gold currently hovering around the US$1400/ozT mark, that gives a scrap, or "melt" value of US$4380, and most scrap dealers pay no more than about 80% of melt (many pay less!), so you would be doing well to get more than about $3500 for this as scrap. 3 of my P1s were "circling the crucible", in the sense that if I had not immediately purchased them, they would have been "disposed of" in this manner (so much for the notion that "no one would melt a P1 to re-cycle the gold"). With only about 50 of the original 400 accounted for (of course, that number is another story onto itself!), the loss of even a single example would be nothing short of a tragedy, to be lamented by all future Pulsar collectors.
Oh, and as for actually wearing one, I DID wear a P1 last April 4th, all day, to commemorate the 40th anniversary of the watch, and, I did again at the NAWCC National Convention last February, and on both occasions, it did attract comments. Still, I must admit it was a relief to put it safely back in the vault (unharmed) at the end of the day!
