With Official Controlment Offices for the Rating of Watches Watch Rate Certificate and card dated 1 August 1930 and Rolex period leather presentation box.
The present timepiece is distinguished by its remarkable overall condition and its superior quality movement: at the time, Rolex movement could be of three qualities: Prima, Ultra Prima and Extra Prima. The Ultra and Extra Prima versions allowed for adjustments to position and temperature. The present watch not only features indeed a superior Extra Prima movement, but it also bear on the bridge the designation “Observatory Grade”, indicating an even higher level of accuracy.
A final layer of appeal is given by the Glasgow import stamps inside the case back, denoting the original destination of the piece. Watches shipped to England were usually shipped dismantled, and reassembled once imported. For this reason, the case number engraved on the case back is repeated on the inside of the case body, so that the two pieces would not be mismatched during the reassembly process.
