Kirov double marine chronometer set
Record status
Individual type · partial
Period
circa 1960
This lot consists of a double marine chronometer set manufactured by Kirov, dating from the period around 1960. The chronometers are housed within a brass-trimmed wooden box that includes electrical contacts and an on/off switch, measuring approximately 11-3/4 inches by 6-3/4 inches by 7 inches.
Each of the two chronometers features a fusee movement with a detent escapement and a 56-hour duration. The dials display power reserve indicators and are signed in Cyrillic, with consecutive serial numbering. The movements are fitted with helical hairsprings. The set includes a winding key, a locking box with its own key, and an instruction manual. The auction description reports that the movements are running as of the time of cataloging, though accuracy and power reserve duration have not been tested.

- Casing and Mounting
- The two chronometers are mounted within a shared wooden box featuring brass corner reinforcements and trim. The movements are secured using a gimbal system, which maintains their orientation. The housing is designed with functional integration, incorporating three electrical contacts and an on/off switch. The total footprint of the assembly is approximately 11-3/4 inches by 6-3/4 inches by 7 inches.
- Condition and Accessories
- However, it notes that no testing was performed regarding the specific accuracy of the chronometers or the duration of their power reserves. The set is sold in its current state, with the recommendation that service may be required. The set is accompanied by several original components, including a winding key, a wooden locking box with its respective key, and an instruction manual. A file of associated paperwork is also provided.
- Movement and Dial Construction
- The chronometer set comprises two individual 56-hour clock movements. These are constructed with fusee and detent escapement mechanisms, which serve to provide consistent force and timekeeping regulation. The movements are further equipped with helical hairsprings. The dials are designed with dedicated power reserve indicators, allowing for the tracking of the winding state. The dials are marked with Cyrillic script and feature consecutive serial numbering, confirming their paired configuration within the set.
