The English watchmaker Thomas Prest was one of John Roger Arnold's most able workmen and apparently made some of his best watches. In 1820 he patented a form of keyless winding mechanism, patent no. 4501, which was occasionally used by Arnold.
A year later, Prest started business on his own account at Chigwell Row which after his death in 1855 was continued by his son, Thomas Prest.
