FINE, 19TH CENTURY, MARINE CHRONOMETER WITH ADMIRALTY MARKINGS. The 4" diameter silvered face beautifully script engraved "Robert Molyneux/30 Southampton Row London 2186". Has Admiralty broad arrow within the second hand dial. Blued steel hour, minute, second and up/down hands. Domed glass bezel. Mahogany box with inset brass corners, key escutcheon and ornate top plaque. Brass carrying handles. Front with an ivory disc that is engraved with Admiralty arrow and "Molyneux/2186". Also has a smaller inset ivory disc marked "2 DAYS". Box size 6 1/4". Condition overall very fine. Has an outer storage box that is a later replacement. This chronometer was sent to England in 1978, by my dad, to the famous Thomas Mercer firm for a complete overhaul and rating( all paperwork and correspondence included). The small top lid may be a replacement but I'm not positive. In his book Tony Mercer lists this exact chronometer as being made in 1841 which is probably about right because it's fitted with Molyneux's auxiliary compensation balance which he patented in 1840. An important marine chronometer and especially nice with the broad arrow mark denoting acceptance and use by the British Royal Navy.
