This 18K gold keyless center-seconds pocket watch, manufactured in 1915 by Patek, Philippe & Cie of Geneva, features a 48 mm diameter case. The watch is constructed as a four-body 'bassine' case with a polished finish and a hinged gold cuvette.
It is powered by an 18-ligne movement measuring 40.3 mm in diameter, decorated with rhodium-plated 'fausses côtes' patterning. Technical features include 21 jewels, a straight-line counterpoised lever escapement, a cut bimetallic compensation balance, and a blued-steel Breguet balance spring. The movement is fitted with eight adjustments and a swan-neck micrometric regulator. The silvered dial displays a bâton hour chapter with applied gold Arabic numerals at the quarters, an outer minute track, and an outermost seconds scale with five-second Arabic markers.
Gold 'feuilles' hands indicate the time. The watch was sold to Texeira Santos on November 18, 1943.
