The present watch is part of a small series of gold coin watches, given reference numbers 800 to 809, using different coins such as
US$5 (ref. 800), US$10 (ref. 801), US$20 (ref. 802 & 803), CHF100 (ref. 804), Pesos 50 (ref. 805) and others. No other coin watches were since made by Patek Philippe.
It is preserved in very good overall condition and believed to be one of only four examples of a reference 805 to have appeared in public to date.
