Lately I have been drooling over these:
I have to say, if I had ~$75,000 lying around, it would be one of these two. As much as I love the finishing of the PD, something about that KV really draws me in. Such an interesting looking watch.
Three other suggestions you may have missed:
JLC Master Memovox International
Glashutte Original Senator Hand date (2 register black dial similar to the IWC but no power reserve)
Zenith El Primero Striking Tenth (I dont think you missed this one, but it certainly is more unique than the vanilla one--I dunno if id pay the premium for it tho)
Random subjective thoughts:
1. If I really had my heart set on a chronograph, id probably take the Zenith over the JLC
2. I prefer the minimalism of the MUT Moon to the busy face of the MC
3. I like the Memovox International, I just dont know if the time shifts when you change time zones so thats something to look into. Iif it doesnt then its just a little too pricey for a limited edition with no real complication
4. Make sure you know which ones have an exhibition caseback if that's important to you, especially if youre looking at vintage JLCs versus new ones
5. The open caseback on the Zenith striking 10th is amazing. I have not seen the others in person though
As for the original style or Royal Oak, love it or hate it, it's the original luxury sports watch. It started a trend that PP, VC, and IWC followed up with after a few years. I think its a clean and original design and the movement in the "Jumbo" time only (no seconds hand) is still considered one of the finest and thinnest automatic movements ever used. It was developed by JLC and at one point AP, PP, and VC were all using it. JLC never used it in any of their watches.
As for the Offshore models, I find them loud and silly looking. I am just not a fan of lots of rubber, carbon fiber (fancy plastic), and other odd matterials that resemble plastic on a watch. I also think large colorful watches are often worn by people seeking attention for their purchase (and themselves). Afterall, how can people not notice something the size of a tuna can with bright dials and straps? However, I think part of the attraction, is from speculators. The "End of Days" edition coveted by collectors, worn by Arnold Schwarteneger in the movie of the same title developed a cult following and its price in the second hand (no pun intended) market started to sky rocket. Then AP released a few more limited editions, and I think speculators snapped them up driving prices up and now people will by any of their limited editions with the idea the prices might go up. I find they have released so many limited editions that there is nothing limited or special about most of them. Not to mention, they have done limited editions celebrating people and bands I don't care about like NSYNC? Really, did they need to celebrate NSYNC? What will they give us next a limited edition Offshore for people that switch from Crest to Colgate toothpaste? I think an occasional special model to celebrate a company anniversary, a very special event, or someone truly unique may be worth while. I find when a company releases too many "limited editions" that are really the same watch with a differnet color strap or dial after a while it becomes tiresome and cheapens the brand. But I suppose as long as people continue to shell out money for limited editions we will continue to see them.
