Very fine 18K gold keyless pocket chronometer a Tact, with one minute tourbillon regulator, in original mahogany fitted box with certificate No. 41. Three piece, massive, "bassine et filets" the reeded band with gold touch pieces, crystal back with gilt Breguet numerals and gold revolving a tact hand. Gold engine-turned with Roman numerals on a polished chapter and outer minute ring, offset subsidiary seconds and 48 hour Up-and-Down sector. Blued steel Breguet hands. Notes This chronometer is based on the Ebauche which established the unsurpassed world record of reliability and precision at the Observatory and has been individually made, using as far as possible, the original methods and machines. Some of these machines date well before 1870 and are museum pieces in their own right. However, they have been lovingly restored by Thomas Engel who had to relearn the traditional skills, since their method of operation had been lost many years ago.
