Nice to see this post on X-33s and also to see old posters I had read when I got both gen1 and gen2 years ago. Just pulled out the gen1 and had a battery change (in Osaka Japan) for $35.00). My gen2 also had lay dormant in the collection and needed a new battery. I was having trouble synching hands to digital time so I put the watch away. Yesterday I sent it to the Tokyo Swatch Group service center and got some prices: $218usd for battery, pushers changed and sonic cleaning. Overhaul: $417usd includes replacing to newer 1666C version.
