James Walter Benson, 62 & 64 Ludgate Hill, one of London's premier retailers of good and top quality watches from before the 1880’s. Makers of their own wristwatches from 1910, they continued to retail many Swiss made models. NB: Benson sold a variety of different models under the 'Tropical' name over the years, this being perhaps the most interesting of them all and the only one so well appointed. This model originally cost 6 guineas in a stainless or silver case, with cases also in 9 and even 18 ct - see the copy I show of Benson's advert from the period.

The dial with the usual hair crack (at the bottom and barely visible), otherwise in fine original condition showing few signs of age. On a new/old stock black leather strap with stainless-steel buckle and loop, a perfect match in my opinion. Serviced and guaranteed.
