Object description

Case and Dial

The timepiece is constructed with a sterling silver 935 case, which shows visible signs of age including surface patination and spotting. The case back is decorated with an engraved monogram. The white enamel dial is printed with black Arabic numerals and features a perimeter track with five-minute intervals indicated in red text. A subsidiary dial for constant seconds is located at the six o'clock position.

The dial exhibits hairline cracks consistent with the age of the enamel. A central red hand, integrated into the chronograph mechanism, serves as the primary indicator for the one-minute timing function. The case, dial, and movement are signed by Tiffany & Co.

Mechanism and Chronograph Function

The watch is powered by a manual-wind movement, described as a chronometer mono-pusher. This mechanism allows the operator to control the chronograph function through a single pusher, activating the central red hand.

As a mono-pusher, the watch operates the start, stop, and reset functions through the crown or a dedicated pusher. The technical details regarding the specific caliber or escapement type are not provided in the source documentation, which notes that movements or parts of mechanisms may be incomplete in sold lots.
