Jaeger-LeCoultre Master Ultra Thin Moon 39

Seamaster versions
Hi Folks, settling on getting a Seamaster again (first one in 2000, gifted to Son some years ago and still in great shape) and I want the classic blue wave 41mm waveface 2220.80.00. I did notice that there is also another smooth blue faced 41mm 212.30.41.20.03.001. The later one is slightly more expensive, but other than this I don't see any difference other than the face. I prefer the original with white date and wave so I'm going down this route, but have I missed anything?

Gotham Chronograph info
I found this at a flea market for 2$ today, I purchased it so I could have another donor watch to take apart and practice on, but after a little google foo I am thinking this is too valuable to risk not being able to get it back together especially after looking at this complex movement. I could only find a few chronographs slightly similar and they were going for a pretty penny. of course condition is everything and this one is lacking a good dial, but wow what a dial. its simply amazing if you ask me.any thoughts or opinions? it has a swiss movement that i assume is ETA but the only numbers I can see on it are 2593 is that a known ETA movement?If you were me would you put in on the 'bay as is, or just go ahead and tear it apart and treat it like the $2 watch that I paid.IMG_0023.jpgIMG_0024.jpgIMG_0025.jpgIMG_0026.jpgIMG_0027.jpg

Apple watch: cool useful gadget or totally useless
It's been a week since Apple announced their latest and newest products, among which was the rumored Apple Watch.I don't think I have seen another thread here with regards to this.Jake wrote on his Rolex blog:

Collection Construction
I'm considering purchasing a ROO 44mm to add to the rose gold equation of time I just purchased and am having trouble deciding between the RG and the Plat. The RG sings a bit more to me on my wrist, but obviously it's a bit duplicative of the EoT. When all you handsome gentleman are assembling your collections, do you just go for your favorite watch in a vaccuum, or try to add some variety to avoid replicating the same general look throughout?

Cracked dial
I recently purchased a pre-owned PAM 051 from a well-established pre-owned dealer. The dealer offers its own 1-year warranty, and also has its own in-house watchmaker. I have had the watch less than two weeks, and have only worn it three times since receiving it. The third time I wore it, I noticed an imperfection on the dial that only shows up when the light hits it a certain way. In many lighting situations, it is fairly unnoticeable, which is why I did not see it right away. However, it is also the kind of blemish that, once you know it's there, you see it every time you look at the watch. Under a loupe, I can see the imperfection is actually a hairline crack in the dial, resulting in a slight upward buckling of the dial surface in that area. The crack starts at a lume dot, and runs straight through several minute hash marks. My loupe has a measuring square, and I have measured the crack to be approximately 4mm in length. The dial itself is only 34mm in diameter (the case
