History: The Rebberg watch movement was named as such because the location of Aegler's factory was on a street called - you guessed it - 'Rebberg'. This is a lever escapement movement with a cut bimetallic temperature compensation balance with Breguet overcoil balance spring. The Rebberg movement had a good long run - 1902 to 1927, but it was eventually replaced by Aegler's new line - the Hunter.

Info: The Aegler watchmaking company was established in Biel / Bienne in 1878 by Jean Aegler. Biel / Bienne is on the language boundary between the French and German speaking parts of Switzerland, hence the dual name for the town. Biel is German, Bienne its French counterpart.

Hermann Aegler made ebauches (unfinished movements) of a small size. After Rolex was founded they started importing Aegler’s movements and used them to make a variety of “wristlets,” selling them principally in the UK and in the British Empire, above all in Australia and New Zealand. His belief in the wristwatch format was confirmed by a precision test at Kew Observatory in London on 15 July 1914, when a 25-mm Rolex “wristlet” attained a Class A certificate, previously won only by much larger pocket watches.

Although Aegler was a completely separate legal entity than Rolex - it was owned by the Aegler and Borer families - starting in 1936, they only produced watches for Rolex and operated as a subsidiary of the Rolex brand. Eventually, in 2004, Rolex completed the legal acquisition of Aegler and Aegler became a de jure as well as de facto division of Rolex. For this reason, movements made by Aegler from 1936 on are considered "In-House" Rolex mechanisms as they were only available in Rolex products.
