This manual-wind deck chronometer by Victor Kullberg features a split-seconds chronograph and an up-and-down 30-hour power reserve indication. Housed in a gilded brass case within a fitted glazed mahogany box, the timepiece features a white enamel dial with Roman numerals and blued steel Breguet hands.

The source describes the movement as a 20-ligne gilt brass three-quarter plate caliber with fusee and maintaining power, an Earnshaw-type spring detent chronometer escapement, a cut bimetallic balance, a helical blued balance spring, and a diamond endstone. Guildhall Museum ledgers record its manufacture for Major Rivers on August 14, 1923.

Identity and Archival Ledger Record
Movement and case number 9563 identify this manual-wind spring detent deck chronometer attributed to Victor Kullberg. The catalog notes that both the dial and movement bear the maker's signature. According to catalog notes citing the Kullberg ledgers held at the Guildhall Museum, entry No. 9563 records that the watch was made for Major Rivers on August 14th, 1923. Accompanying items listed in the lot include an original fitted mahogany lockable box and a copy of Kew Class A Kew/Teddington Observatory Trials documentation.
Dial Presentation and Observed Condition
The instrument displays a white enamel dial with Roman numeral hour markers, an up/down power reserve register under 12 o'clock, and central split-seconds hands. Photographic observation confirms the Kullberg brand inscription across the dial face, housed within a glazed mahogany box. Catalog condition grading records a hairline crack within the enamel dial and notes original hands. The source condition assessment also advises that an overhaul is recommended at the buyer's expense.
