Well, I really like the Space Black SS Bracelet 42MM for $1099. I'm not sure if I like the SS with sport band ($599). I had a Citizens Divers watch which the rubber strap was affixed to the case, and on two occasions, the rubber strap cracked and I had to send the entire watch in for service.
Since then, I've never purchased a watch with a strap thet I can't replace myself. I question the durability of it. Now, take a look at the SS with Black Modern Buckle, it has a loop on both top and bottom of the dial. I wonder if this loop can be unscrewed to replace the strap. The downside, it's offer only in 38MM ($749) not 42MM.
All of the bands are easily replaced with the mechanism that holds them in place. There is no need to remove the leather from the connector. Apple has created a connector to swap bands in a matter of seconds. It's one of the biggest selling points.
