  Chelsea Clock Company Serial Numbers

A common question we receive from clock collectors, and antique clock shoppers, is the age of a Chelsea Clock based upon serial number.

Every Chelsea Clock containing the Chelsea Ship's Bell mechanical movement has a unique serial number assigned to the movement. Movement serial numbers have been recorded since 1897, originally in leather bound books, and today on computer.

To help answer the question of age, we have provided the Chelsea Clock Company serial numbers for these movements, from 1897 through 2004. This information will indicate the approximate date of manufactuer for an authentic Chelsea Clock containing a Chelsea  mechanical Ship's Bell movement.

In some cases, a number located on the exterior of the clock itself is not the movement serial number. In this circumstance inspection of the movement itself will determine the correct serial number, and authenticity. This requires disassembly of the clock.

Windward Instruments strongly recommends this service be performed only by Chelsea Clock Company.
