My Citizen Ecodrive needed the first capacitor change after 17 years of daily wear. Literally zero service to the watch before that.
Also I really really don't buy that this mechanical movement won't need service every couple years like pretty much any mechanical watch out there. Where do you take the decades part from?
Probably the ruby that the spinning parts sit between and only need to be relubricated occasionally. I'm just going of what I've seen on service videos.
