Marine chronometer, with brass and mahogany case, by Jas McCabe; London, England, mid-19th century; dia. 4” (10.7 cm.).
This typical marine chronometer is mounted in gymbals in a stout mahogany box with brass corners to protect it at sea.
The first maker named James McCabe died in 1811 and his business was carried on under the same name by his descendants till 1883, making it difficult to date any given piece.
The seconds dial is large and clear. Beside the figure XII is an indicator to show if the chronometer needs winding. It is imperative that a chronometer should not stop at sea. The key is kept in the top right hand corner of the case.
