You've raised a good question. An excellent topic!
Firstly I can't "stop wearing an Apple watch", simply due to the fact that I've never had one!
But as a long-time watch collector and big fan of Apple products since the purchase of my first Ti PowerBook G4 back in 2001, I anticipated the release of the Gen1 AppleWatch some 8 or so years ago with great enthusiasm. And I was fairly sure I would purchase one to add to my collection of watches and other Apple collectables.
However on reading the first official reviews on MacWorld and elsewhere I was in for a disappoinment - although no doubt tens of thousands of buyers were highly delighted - and still are.
Although I found the design and build quality pleasing, it was news of the battery 'life' - or rather lack of it - which was an immediate turn-off. Some slight improvements to battery autonomy appeared with subsequent models but there was no way I could live with a watch which required recharging several times a week or perhaps every day depending on use, given that my other electro-mechanical watches (60's Bulova Accutron, '74 Omega Speedsonic f300 etc) would function for 12months+ and even up to 2 years respectively - with a watch almost 50 years old!. Plus when required I can change the button cell battery in 4 minutes. I've never tried that on an Apple watch and don't plan to.
So related to your original query, instead of purchasing and wearing an early Apple watch, around 2015 after a fair amount of research I bought a Seiko SKX007 auto mechanical 200m diver watch, and very pleased I did as it's still in impeccable condition with original box and papers - plus it's value has soared X3 from what I paid originally. Had I bought an early AW I'd probably be lucky to recoup even the original price (unlike an original iPhone1,1) which I recently sold.
You mention the Cartier Santos, a model I know quite well, especially the auto versions, and although a very pleasant dress watch, not quite my style. Actually I bought one for my wife over 25 years ago, and she"s worn it only twice since.... 😢 Info in the second part of my blog
