I have for sale a manual wind Longines in a 14kt yellow gold case with a mystery dial. Case: The 34 mm case is 14kt yellow gold. The hallmark says K+H I think. I believe that it was cased in the United States. There wear consistent with age. Crystal: The crystal is not original and has some scratches. Movement: Runs and keeps time. Service history is unknown. It been neither worn nor serviced while in my possession (at least 7 years). I am not sure what movement it might - I thought perhaps a 23zs. Someone here may have an idea. Dial and Hands: The dial is original and in fair condition. It has patina as can be seen on the pictures. The markers are gold with black inserts. the minute hand looks original as well. Crown: The crown is worn - it can still be used to wind the watch but the new owner may consider replacing it at some point. Strap: The strap and buckle are not original. Price: 300 USD (or reasonable offer) including shipping to the Continental US with FedEx (or USPS registered). The watch is in Los Angeles. Photo: Video:
