This maritime magnetic compass is mounted within a gimbal ring system designed to maintain a level orientation at sea. The polished brass bezel is engraved with the maker mark W. Ludolph Bremerhaven. The internal compass card features the brand name Observator and is inscribed with the serial number 4470. The card uses Dutch cardinal and ordinal points: N (Noord), NO (Noord-Oost), O (Oost), ZO (Zuid-Oost), Z (Zuid), ZW (Zuid-West), W (West), and NW (Noord-West). The outer brass bezel is graduated with a full 360-degree scale, marked in single-degree increments with numerical values every ten degrees. The instrument is contained within a heavy cylindrical housing, likely constructed of brass or bronze, which displays a dark, weathered patina. The compass is liquid-filled for damping.
