LonginesThis gentleman's wristwatch, produced by Longines and bearing the serial number 4223671, was delivered on October 28, 1926. It is constructed with a four-body sterling silver case measuring 35 mm in diameter, featuring a polished finish, straight lugs, a rounded bezel, and a hinged case back with an interior silver cuvette.
The matte silver dial is equipped with radium-coated Arabic numerals and skeletal hands, incorporating two auxiliary guilloché registers for constant seconds and a 30-minute chronograph count, plus an outer fifths-of-a-second track. The movement is a gilt brass Caliber 1333 containing 18 jewels, a straight-line lever escapement, a monometallic balance, and a self-compensating Breguet balance-spring. Chronograph functions, including start, stop, and return-to-zero, are operated via a single coaxial button integrated into the winding crown.
The dial, case, and movement are each signed by Longines.

- Case and Dial Construction
- The watch is housed in a four-body solid sterling silver case featuring a polished exterior. The design utilizes a rounded bezel and straight lugs, with a hinged case back that reveals an internal silver cuvette. The dial is finished in a matte silver and features radium-coated Arabic numerals. Time and chronographic information are displayed through two auxiliary guilloché-patterned registers: one for constant seconds and one for the 30-minute chronograph totalizer. The perimeter of the dial is printed with a scale divided into fifths of a second to facilitate precise timing. The hands are skeletonized and also treated with radium coating to improve visibility.
- Condition and Identification
- The auction description provides a grading assessment for the watch, assigning a 'Grade A' status to the overall piece. Individual components are graded numerically: the case is assigned a grade of 3, the movement is assigned a grade of 3*, and the dial is assigned a grade of 2. It is noted that an overhaul for the movement is recommended for the future owner. Authentication of the watch is supported by the fact that the dial, case, and movement are all individually signed by the manufacturer, Longines. The watch is further identifiable by its serial number, 4223671, which correlates with the documented delivery date of October 28, 1926.
- Movement and Chronograph Mechanism
- The timepiece is powered by the gilt brass Caliber 1333, which contains 18 jewels. The mechanical architecture incorporates a straight-line lever escapement and a monometallic balance paired with a self-compensating Breguet balance-spring. The chronograph functionality is managed via a single coaxial button located on the winding crown. This mechanism provides the user with control over the start, stop, and return-to-zero functions of the chronograph hand and associated registers, streamlining the interaction between the wearer and the complications of the watch.
