Rare Excelsior Park Rational Rattrapante Stopwatch, ca. 1960
"Rattrapante" means there are 2 hands for stopping intermediate times. If you press the crown once, one hand stops and the other continues running. If you press it a second time, the stationary hand closes again to start running.
For the expert, the high-precision movement, although unsigned, is easily identified as an original Excelsior Park movement by the Excelsior Park-typical spare parts compartment. Rational was a trade name under which Excelsior Park marketed its high-precision stopwatches.
50mm case diameter, white, unrestored, flawless dial, metal case, perfectly immaculately preserved dial with rare 100-second scale, 60-second scale and 30-minute counter, original blued steel hand, very good condition, functional.
This rare piece of (military) watch history starts and runs (accuracy not tested)
EZ 2: Good condition for its age! Barely any noticeable signs of age or wear, runs smoothly, dial flawless, sometimes you have to press several times to reset the second hand to zero. We generally recommend a service for watches of this age.

Swiss watchmaking
Excelsior Park was founded in 1866 by Jules-Frédéric Jeanneret in Saint-Imier as the watchmaking business JF Jeanneret. In 1888, Jeanneret's three sons took over the company. Samuel Jeanneret continued to run the older company Veuve Jules-Frédéric Jeanneret. Albert Jeanneret then founded Albert Jeanneret & Frères and in March 1891 Albert Jeanneret applied for a patent for a chronograph. In 1893 he left the factory to his sons Henri Jeanneret-Brehm and Constant Jeanneret-Droz who separated again in 1902. Henri continued the company under the name Jeanneret-Brehm & Cie. Constant initially worked on his own account and in 1912 bought the Leonidas watch factory.
When the heyday of timepieces for sports enthusiasts began in the 1930s, the company launched an exceptionally wide range of timepieces under the Exelsior Park brand name, also incorporating chronograph calibers from other Swiss manufacturers. The company was so successful with this range that it began developing its own calibers. These successes and numerous honors testify to its high status. Excelsior Park also supplied chronograph movements for companies such as Gallet & Co. , Zenith , and Girard-Perregaux .
