A very fun thread! Thanks.
Yes, each will sell.
Favorites. Least favorite first, date and monza. Not a fan of dates, especially on a speedy, so rarity doesn't make it better. It's still an awkward date. Monza is not bad, just not a favorite with the yellow. Seems a little washed out compared to the subdials. Don't like comparisons to rolex, but even though it is inevitable, this Omega does it better. The rotary monza was a fun engine. The revs were insane. Not sure it was worthy of a watch, though. Also skeptical of so-called prototypes. But it'll sell.
Alaska, like everyone else says, is great. Not sure it'll be an overall high percentage winner but it'll do well. What's not to like (other than the FBI knocking on your door and taking your watch.)
Gold speedy is nice and will sell. Can't imagine it being much higher than 50k when you factor in the buyers premium.
Ultraman will sell. Me, I'd rather have Eugene's put together racing dial. Big bucks for Ultraman is a tough sell for me, at least when the choice is the moonshine vs Ultraman money.
I don't know the 2998 market well. It seems out of my reach so I tend not to follow it. The 2998-1 hands are beautiful, like you said. I have noticed that an otherwise nice watch with bad hands will always be disappointing. Once you see bad hands you can't unsee them, especially if everything else is nice. It's like they jump out. These hands elevate the whole watch. I would guess that a buyer would get warm fuzzy feelings whenever they looked down at their wrist wearing this. It's a favorite.
The apollo-soyuz is my favorite and best buy. The pushers are awkward but could be replaced. It has the right case, which is the biggest issue when missing. It is number 076, per Phillips extra pictures and was previously sold around 26k. At 20k i might be a buyer. The serial number is right, the dial and hands properly aged, it even has dirt around the pushers. I think this has the potential for highest percentage over estimate.
Like you said, pictures are very good. After asking for additional pictures, they sent me a folder of high quality picture from multiple angles. Kudos.
Thanks for this thread. Fun to imagine owning any of these, even if fantastical.
Good luck to the sellers and buyers.
