Henri Chatelain - Contapassi / Pedometro Meccanico da Tasca - H

Rare and fascinating antique pocket mechanical pedometer (step-counter), produced in France in the early 20th century (circa 1900–1920) and traceable to the renowned Henri Châtelain manufacture. This walking scientific instrument combines the elegance of a classic pocket watch with the precision of mechanical engineering of the era. Its operation is based on an ingenious internal pendulum system (oscillating mass) that records the jolting movement of every single step, transmitting it to the hands on the dial. Details and Features: • Dial: Stunning white enamel dial in excellent condition. Main peripheral scale graduated from 0 to 100 steps with large Arabic numerals. • Sub-dials for total count: • Left sub-dial: counter up to 25,000 steps. • Right sub-dial: intermediate counter up to 1,000 steps. • Hands: Refined original blued steel hands that create a magnificent chromatic contrast with the white background. • Case: Pocket-watch style case (gousset) in steel with a top suspension ring at the 12 o’clock position. • Dimensions: Diameter of about 45 mm (excluding crown for winding/suspension). The object presents in generally [excellent / very good] condition for its age. The case shows a beautiful patina of time that enhances its historical charm [mention any small scratches or signs of wear if present]. The mineral crystal is intact and clear. • Mechanism: Fully Functional: The internal oscillating mechanism is free and responsive; moving the instrument produces the correct internal click and the hands advance, but it has not been tested for precision over long distances. A stunning collectible piece, highly scenographic, perfect for enriching a display of scientific instruments, antique curiosities, or historical horology.
