The finely designed and constructed pivoted balance with gold counter-balancing weight is a possibly unique feature of this chronometer. No.410 was issued to the following Royal Navy ships:
1818: H.M. Surveying Ship Shamrock, Captain Martin White RN, surveying the English Channel, the Irish Sea and the Bristol Channel.
1822: H.M. Surveying Ship Kangaroo, surveying brig, Master Anthony De Mayne, RN, surveying the West Indies particularly the Gulf of Florida, Cay Sal, New Providence, Nassau and Jamaica. No.410 was used in determining the latitude and longitude of these places. During the period she was surveying, Kangaroo was struck by lightning and two of the chronometers onboard her ceased to function -- this necessitated their being replaced. Arnold No.335 and No.410 were sent out to Port Royal and De Mayne had to break off his surveying and go to Port Royal to collect them.
1833: H.M.S. Firefly, Schooner, Lieutenant Commander John J McDonnell RN, on the North America and West Indies Station, No.410 was issued to him 2 March 1833.
1832: H.M.S. Reindeer, Brig, Captain William Walpole RN, on the Falmouth Station, No.410 was issued to him 2 September 1832.
1835: H.M.S. Curlew, 'Cherokee' Class Brig-sloop, Lieutenant Commander The Honourable Joseph Denman RN, operating off the Coast of Africa, No.410 was issued to him in 1834. In 1836 it was transferred to the charge of Lieutenant Edmund Norcott RN and continued to be used on the Coast of Africa.
