I've had an S1 aluminum for the past year and recently bought an S0 Hermès. My watch never really leaves the face. All it is used for is to track activity in the background. And for time, of course, which is why I got the Hèrmes. All of Apple's analog faces are... lacking. I got the Hèrmes S0 so cheaply that a $79 battery replacement is worth it even if I keep it for a short while and sell it. However, getting an S2 (or higher) would be really awesome. I'm probably going to send it off for a battery replacement either way at $79 but I'm just wondering if anyone has sent a Hèrmes S0 in for battery replacement and what the outcome was. Same watch? Refurb S0? Upgraded to newer gen?
