No, wOS 4 GM has brought a fair amount of speed improvements to my series 2. I bought AppleCare+ on launch day so I'm going to try and take advantage of all 3 years of coverage (2 more years to go). Apple Watch sadly has poor resale value on eBay.
If you end up buying the series 3 Hermes, please take pictures of the unboxing experience and share them with us.
(Other side note: Apple I believe still has a no questions asked 2 week return policy. AKA use the watch for two weeks and return it if you don't like it. Buying directly from Hermes though is tough because once you open the box, they don't accept returns.)
