A rare 18-c yellow gold open face pocket watch from Patek Philippe will be sold at an auction in Oklahoma later this week.
A number of items will be put up for sale at the Apple Tree Auction Center in Newark, US, on August 28 and 29.
Other goods up for sale at the event include more than 750 lots of coins, watches and jewellery.
The Patek Philippe is the top lot of the Unclaimed Bank Deposit Box Contents Auction, and is estimated to sell for around $5,000.
Founded in 1839, Patek Philippe is a Swiss manufacturer of luxury watches and other items, famed for its innovative approaches to watch design and manufacturing.
As well as selling a variety of men's and women's gold watches, it also makes fine gold jewellery crafted from 18-c gold and other metals, including rings and earrings.
Patek Philippe recently created a one-off gold watch to be sold at the Only Watch auction in Monaco in aid of charity on September 24.
