Russian Marine Chronometer

Partially verified

This Russian marine chronometer features a silvered dial inscribed with Cyrillic script 'ПОЛЕТ' (Poljot, rendered by the dealer as 'NOAET') and serial number 7373. The dial displays Arabic hour numerals, an upper state-of-wind indicator, and a lower subsidiary seconds dial marked with red numerals. According to the seller, the brass-housed movement is a two-day duration fusee mechanism with an Earnshaw-design spring detent escapement, cut bimetallic balance, and blued steel helical balance spring. The instrument is gimbal-mounted within an inner glazed three-tier brass-bound mahogany box with a numbered plaque, housed inside an outer protective wooden transport box fitted with leather carry straps.
