The latter information is illustrated on an oval ivory plaque, on the case\u2019s exterior. The case is a three-tier structure with a blank shield-shaped cartouche inlaid to the upper lid. There are three stickers on the exterior (see Marks). \r\n\r\nOn the interior, the lid is adorned with two illustrated notes, one of the manufacturer and one of the repair shop, and a sticker \u2013 two of them behind a Perspex panel, one exposed (see Inscriptions and Marks).

He exhibited his chronometers in Paris in 1867, in Havre in 1868 and won a Grand Medal of Merit at the Vienna Exhibition in 1873. He was a maker to H.M Emperor of Austria, and was awarded the Golden Cross and Crown and made patentee of the centre seconds chronometer. He also trained many craftsmen (Mercer, 1988: 252). \r\n\r\nA chronometer was used to find the longitude at sea by comparing the time on an accurate clock, set to the time at the ship's home port, with that of a measurement of the local time at the ship's position. It was typical for nineteenth century chronometers to be placed in brass bound, square section mahogany cases with double-hinged top and side carrying handles (Baddeley, 1993: 45)."},"onview":{"label":"Public Access","value":"0"},"title":{"label":"Title","value":"Marine Chronometer in Original Case"},"people":{"label":"Artist / Maker / Culture","value":["William Weichert"]},"classifications":{"label":"Classification(s)","value":["Navigation and Timekeeping / Magnetic and Astronomical"]},"beginDate":{"label":"Begin Date","value":"1871"},"node":{"label":"Node","value":"Heritage Malta"},"primaryMaker":{"label":"Primary Maker","value":"William Weichert"},"textEntriesObjecttype":{"label":"Object Type","value":["Chronometer"]},"textEntriesMaterial":{"label":"Material","value":["Chronometer: brass, steel, Glass; Case: wood, ivory, brass"]},"primaryMedia":{"label":"PrimaryMedia","value":"/internal/media/dispatcher/7353/full"},"inscribed":{"label":"Inscriptions","value":"Case Exterior, ivory plaque \"Willm.
