Serial Number 21332095 was reported as inaccurate.

Note: lord elgin 21 jewel ebay no.203074930441
Curator Response: Verified. [eBay #203074930441]. Movement is clearly stamped "21332095" and marked "Lord Elgin - 21 Jewels - Eight Adjustments - Elgin Nat'l Watch Co. - U.S.A." The characteristics are more consistent with the 12-Size Grade 450 classification. The second serial block of Grade 450 movements is 21,232,001-21,233,000, leading us to suspect the #21332095 movement was marked incorrectly, originally intended to be #21232095. UPDATE: This movement has been verified as marked with serial number #21232095 under the plates, confirming the theory that the top plate digit was marked erroneously. https://pocketwatchdatabase.com/search/result/elgin/21232095
