The Old Bond Street location allows to date the movement to 1870-1880s. Samuel Suckley Benson and James William Benson founded the company S. S. & J. W. Benson in 1847.

It's most likely based on Audemars & Piguet blank.
The lever is counterpoised and has a shape of Bishop's cross, which is pointed as specific Audemars feature by H. Zantke in his book "Louis Audemars".
The same author specifies that Audemars along with Piguet was supplied the movements "Genre Anglais" (in English manner) via their London office to main British watchmakers, including Dent, Frodsham and Benson.
Escapement is Swiss lever, which is one extra sign of Swiss origin of the movement.
The balance bridge features "star" mark between Fast and Slow.
According the book "the English Watch" by T.C. Cuss, this mean that movement was finished on the Coventry's factories.
The same book states that Benson was offering watches equipped with Swiss design and US movements as well within it shop.
However a lot of clients were agree to pay extra premium when they've seen the British movement..
