The CB0120-55w is a very rare limited edition green version of the CB0120. I bought this on the yahoo auctions Japan site. You can see reviews of the more common color versions around the web. It comes in a large display case, with all links installed, and will fit up to a 21cm wrist. It has the rare and desirable hidden 3-position ratchet micro adjust in the clasp, similar to the PMD56 line, but slimmer (see photos). This piece isn't pristine, and has a lot of wear marks on the case and band. The crystal is clear. The common colors (black or white faces) seem to be $3-400 used and 500+ new.

Excellent world radio/atomic H145 movement with time zone quick set "Direct flight", and a mile-long list of other features, including perpetual calendar, anti-magnetic, impact resistance, auto hand correction, etc.

Comes with clear-top display box and outer box, no papers. Cat for scale
