History: The Hunter 10 1/2 Superbalance was introduced in 1935 with Swiss patent 188077. This new model replaced the earlier Hunter 10 1/2's which were graded according to their timekeeping accuracy. The new series was only manufactured at a single quality point. Superbalance movements from the perios 1935 - 1945 were occasionally made with 16, 17 and even 18 jewels. In certain cases the endstones are enhanced with screwed chatons. In very rare cases, sapphires are used in place of rubies. The appearance of the text "Patented Superbalance" on the mechanism is the best indication that you are looking at a Superbalance and not a basic Hunter 10 1/2 (which are labeled "Prima", "Extra Prima" or "Ultra Prima". However, to confuse things, the Superbalances are also labeled '10 1/2" H'.
Manufacturer:
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.

Until 2004, 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 if they were a subsidiary of the Rolex brand. Aegler even changed its legal name to be more "Rolex-like". 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 to 2004 considered "In-House" Rolex mechanisms as they were only available in Rolex products, despite the fact they were made by Aegler.
