This may be a strange thought, but I wish that Omega would focus on their bracelets as much as they focus on their movements. They are bringing all kinds of innovations to movements--and that is important. They should be commended for that. But my Aqua Terra Small Seconds has no on-the-fly micro-adjust whatsoever (the only downside to an otherwise incredible watch). I know they are finally bringing a micro adjust to the Speedmaster Professional, and, again, that's great. But their solution is still not as good as Rolex's easy link adjustment. Also, Omegas are often strap monsters (Speedy especially), but they use old-fashioned spring bars. They should have a quick swap system--like, say, the Cartier Santos.

Take some of the brains that are doing such great things with movements, and have them spend a few years think about on-the-fly bracelet adjustments and quick swap straps/bracelets. I'd get much more utility out of that kind of innovation than a 0/+2 seconds movement regulating system. And why not do both?

Can’t beat the JLC Ultra Thin Moonphase. 

This is what I do. I wear an Oura ring and get basically the same functionality as a smart watch, but my wrist is free for my mechanical watch rotation. It works great.  

I reserve this for days when I’m doing serious lawyering and I want an extra edge. 
 

I think the problem is just with the Santos because of the special end links. Here’s a link from their site:

I think I can speak from authority on this one. I’ve owned the Santos (large) for more than a year, and I just bought the Tank XL yesterday (literally). 
 

I love just about everything about the Santos. I very often get compliments on it from non-watch people. The interchangeable strap system is amazing. However, one bad thing on that note, Delugs was the best source for compatible straps, but Cartier is apparently cracking down on them by enforcing a patent. That means the only source for additional straps will be Cartier, which does not do online sales, takes months to get a custom-made strap, and is way, way overpriced. 

As far as the Tank goes, I went to the AD planning to buy the large size Tank. I thought because the large Tank Must is the same size as Tank Louis Cartier, it would work for me. But it was actually really, really small on my 7.25 inch wrist. The XL, which I thought was going to be too big for a Tank, is actually a perfect size for me. It also has the advantage of being a mechanical movement and having a beautiful silver guilloche dial—instead of the flat white dial of the smaller models. (I’m attaching a picture.) So I went with the XL, and I’m very happy with that decision. 
 

Which is better? Close call. I’m in the honeymoon phase with the Tank right now, but on the whole the Santos is probably the more flexible piece—it can be formal or sporty or anything in between. 

Not to be to nitpicky, but it was actually worn on the lunar surface by Buzz Aldrin during the Apollo 11 EVA—not Neil Armstrong. Aldrin and and Armstrong both had Speedmasters, but there was a problem with the mission clock in the LEM, so Armstrong left his Speedmaster in the capsule in case they needed backup. Of course, the Speedmaster was subsequently worn on every other Apollo mission. (Though Dave Scott wore a Bulova during the third EVA on Apollo 15.)
