A fine gorge-cased grande-sonnerie carriage clock by Drocourt of Paris with an unusual Drocourt trademark and retailed by Leroy of Paris.

​

The eight-day duration movement has a silvered platform lever escapement and can be set to full grande-sonnerie strike (both hours and quarters at each quarter); petite-sonnerie (quarter striking) or silent via a lever set within the base. The backplate is stamped with the usual Drocourt D.C. trademark and serial number 21195, along with a further stylised AD mark, number 4890 and Leroy number 13693. One side of the movement plate is engraved for the retailer; Le Roy et Fils, 13 et 15 Palais Royal Paris 13693.

The white enamel dial has black Roman numerals, blued steel moon hands and a subsidiary alarm setting dial below VI o'clock.

​

The gorge case has the usual five-bail handle. 

This additional trademark of a stylised AD must be short-lived as I have not seen it on any other Drocourt clock with serial numbers close to this one, nor further apart. The number 4980 is interesting as it does run in sequence with the Drocourt grande-sonnerie movement numbers at this time that are found within the movement and not visible, as opposed to the clock serial numbers which are stamped on the backplate. This is the first example noted with the movement number also stamped on the backplate of the movement.
