I have both an 1st gen Apple Watch and a series 3. My 1st gen is stainless, sapphire and ceramic, and want to swap the guts of my Series 3 into my 1st gen. Is this possible?

Thank you everyone. I guess I should’ve expanded a bit more on my reasoning why I feel “value” on my question.

I forked out Benjamins on a step up from the lower tier aluminum, ion, composite option. I got my Series 3 as a raffle, and comparing the two, it feels as if the new came out of a Cracker Jacks box, and feels cheap, compared to the kick ass feeling of stainless, sapphire and ceramic back.

There is the “value” I personally see seeking advice, or suggestions. I guess, I could also just sell both, and just fork out the difference.

First-world problems are a darn thing nowadays. Thanks all.
