1962 Lord Elgin Duncan
Interesting, the Lord Elgin Starglo and Duncan from 1955, had a case number of 4909, but had a 21 jewel movement. This version, which has the 23 jewel 770 movement, and is inscribed 1962, has the case number 1577. Outwardly the case is identical to the 1955 model, except of course for the movement ring. The case itself is 14 karat gold.
