Caliber 1556 is an improved version of the caliber 1555. The bridge of the caliber1556 is however still engraved 1555. For technical details see the Rolex spare parts catalogue R20. For a note, see lot 290. The present lot bears two reference numbers, 1807 on the body of the watch, which refers to the specific characteristics of this watch and 1803 in the case back. Refs. 1807 and 1803 are identical with the exception of the bezel. The case bodies and backs were interchangeable at the factory. This watch is illustrated in ?Rolex, Collecting Wristwatches?, by Osvaldo Patrizzi, 2001 Edition, p. 266.
