1910 rare early round silver vintage Rolex watch

A very rare early round silver vintage Rolex watch. The case measures 34 mm in diameter. The rare double-hinged case is marked silver, stamped A (Alliance Horologere, registered in 1910), signed Rolex and numbered 582432. The Swiss jewelled movement is signed Rolex on the under side of the wheel. The white enamel dial has unusual Arabic numerals, which were originally lumed, with a sunken subsidiary seconds dial. The dial is signed Alliance Horologere, Rolex, above the centre. (Rolex may have been added at a later date.)
