Specialist note
The movement of the present watch was made by Thomas Earnshaw for James McCabe. It is fitted with the typical Earnshaw spring detent escapement as well as his "sugar tong" compensation curb.
The "sugar tong" compensation curb was invented by Thomas Earnshaw and derived its name from its pincer-like appearance. This curious arrangement comprises of two arms with one pin on each. The gap between the two pins widened in cold weather and opened in hot weather.
It is generally assumed that he supplied this construction to customers needing a robust watch, hunters for example, as the more common bimetallic balances were heavier and less solid.
