Case: Shaped mahogany, two pieces, front door opens with a blade system, the release being made on a gilt rod on the right side of the cabinet. Door mounted on two pivots, top and bottom. Balance wheel premounted on a large brass bracket, itself screwed to the back of the case. Movement also screwed onto the latter.
Dial: Silvered brass. Main dial in 5 pieces, each assembled with screws to a brass base plate. Outer ring indicating the hours in Roman numerals and a railroad minute track with an oversized line every 5 minutes. The hours and minutes are bordered on both sides by a saute piqué guilloché pattern. Seconds ring revealing the clock escapement and numbering every tens in Arabic numerals, bordered by two lines guillochage en sauté piqué. Railway minute track.
Equation of time indicated on a portion of the barleycorn guilloché dial, completed by a railroad minute track and saute piqué pattern over ~180°.
Numerals from 45 to 15 minutes. The rest of the dial is closed by two half- moons, each pierced to accommodate the winding squares. Engravings filled with black wax.
