Hi Blaine,

Thank you for contacting Mearto with your appraisal inquiry.
Chelsea made thousands of these clocks so they are not particularly rare.
Items linked to Pearl Harbor - one of the most tragic days in the history of the US - are always sought after by collectors and can bring a large premium. If the story that this was from a Pearl Harbor ship can be corroborated with documentation (photos of it on the ship, signed affidavits or newspaper stories of its ownership) it would have a value of several hundred dollars. Without that, and in its current working condition this clock is worth $100-150 (if it does not work, it's worth half that: $50-75).

Based on the photos and information provided, and subject to examination, this is:

A vintage World War II Ship's Radio Room Clock
made by Chelsea
With a painted steel face in a black Bakelite case; this might have been fitted into a wall mount with a hinged glass door/cover.
About 7-8 inches diameter
CONDITION: Surface abrasions and some abrasions to the face. Value assumes this is in working condition.
PROVENANCE: Inherited; by repute but not documented to have survived Pearl Harbor.
$ 100-150*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, or questions/concerns, and thank you again for using Mearto.
