Regarding aesthetics, clearly that's subjective, but many traditional watch enthusiasts (such as Benjamin Clymer of Hodinkee and Ariel Adams of aBlogToWatch) have had a number of good things to say about the hardware design.
From Hodinkee's fantastic Apple Watch piece[1]: "Apple got more details right on their watch than the vast majority of Swiss and Asian brands do with similarly priced watches, and those details add up to a really impressive piece of design"
Finally, to address your initial point, I see no evidence that his software taste is less refined, nor that his hardware work is getting lazy. iOS 7, which I suspect is what you're referring to regarding his software taste, received some negative feedback when first unveiled but has since become well liked, albeit with a few lingering usability concerns, especially since they refined it with iOS 8. The Apple Watch bands alone are incredibly well designed, with a number of improvements over traditional watch bands that the Swiss ought to be ashamed they hadn't invented yet[2]. I'll give two examples.
1. If you've ever changed a leather watch band, you'll know how much of a pain it is. Most people go to a watchmaker to change them. Apple Watch bands are easily interchangeable. How obvious, right? Yet nobody else does this.
2. If you've ever bought a watch with a metal link bracelet, you need to have it adjusted for you at the store. Why? Because you need a specialist tool to do it. If you ever need to change the size, you need to go into a store to get it readjusted[3]. Again, incredibly obvious to make this user interchangeable, yet nobody else did it.
If Ive was as lazy as you say, he would have been happy to use traditional watch bands, the type that every other watch and smartwatch uses, and require users to go into an Apple Store to change them or to adjust them. Two examples of great design, off the top of my head, just for watch bands - I can't imagine how you think he's lazy.

[2] And this isn't due to a lack of innovation. The Swiss (and watchmakers of other countries too) spend a lot of time sweating the details on watch straps, buckles and deployant clasps, e.g. http://www.rolex.com/about-rolex/bracelets.html
[3] In addition, the tools for this often proprietary or vary by brand. Check out the variety of tools that are available for adjusting watch bracelets: http://www.ofrei.com/page237.html Leather watch strap spring bars (the little bit of metal that attaches the band to the lugs) are also often proprietary.
