Au Ministère de la Marine Marine Chronometer No. 4653, constructed between 1827 and 1831, the date of sale and price not recorded. Two-day marine chronometer, with double barrels, and waterproof bowl, in fitted mahogany box. Notes History: Unusually, the sale and manufacturing books do not record the sale date or price of this marine chronometer. It was returned for overhaul on 15 October 1859 on behalf of the Ministère de la Marine. Note: The movement of the chronometer is contained in a cylindrical brass bowl with moisture protection provided by cork gaskets and the screw-fitted bezel. Winding is accomplished by a single square througfn the stepped portion of the bezel, with both barrels wound simultaneously, the intermediate and barrel arbor wheels alI having wolf's teeth. The balance stop arm is also engaged by means of a small square through the bezel, alleviating the necessity of inverting the bowl. A thick glass in the base enables the'back of the movement and the escapement to be examined; a necessity in view of the virtually sealed case. In its layout and design, this chronometer is typical of the double barrel type constructed by Breguet. The box and fittings of this chronometer are well refined; a hinged observation lid with a spring catch replaces the more usual sliding panel, an the system used to lock the bowl in the horizontal position is particularly elaborate. In all this instrument is certainly amongst the most refined examples of the double barrel
