Actually owned the Seiko Spring Drive Moonphase. I owned #120 for a long time. Of course, deep regrets for selling it. This was before GS was introduced to America and the only way was a JDM purchase. Here's some pics from my file. I also have a listing for SNR011 as the model number.
I. have to agree. Quite a bit of watch in the under $1K USD (introductory price) category. I got myself the salmon (more. like copper rose) and the black dial. I like them. I'd even say it was worth the wait
