Hi! For sale: Citizen Perpetual Calendar & Chronograph, BL5400-52A, Full Box and Papers Beautiful watch, perfect balance of tooling with a polished classy look. Only worn a handful of times (less than 10) and I've gotten a comment on it from a stranger ever single time it was worn. Selling to downsize my collection as it doesn't get much wrist time. The polishing around the bezel is an eye-catcher as well as the aviation slide rule. The slide rule is protected and encased under the crystal and can be rotated using the knob at the 8 'o clock position. Video about how to use a slide rule watch for those that don't know yet: https://www.youtube.com/watch?v=F-XxsXp5TEQ Watch is in overall great condition. The clasp has a couple of desk diving marks, but other than that the watch is like new. You can see close ups in the album below. Asking $190 or best offer plus shipping to CONUS. I accept PayPal or Venmo. Album: https://imgur.com/a/citizen-vCcgXTv Timestamp: https://imgur.com/OwpHv2q
