Roth Brothers of New York were initially contracted (from circa 1942) by the U.S. Maritime Commission to source pre-owned chronometers, pocket chronometer movements and other accurate watch movements (such as rail watches and even automobile timepieces - mostly by makers such as Waltham) for re-casing and use on naval vessels. By 1944 Roth Brothers had started production of their own marine chronometers to satisfy demand from the war effort. However, mostly due to competition from Hamilton - who ramped-production of chronometers from around 1942 (most notably their model 21), Roth Brothers production run was very small hence very few Chronometers by them survive.
