Very rare “rattrapante” timer
A Minerva special
Heuer who patented this functionality in 1916 called this type of timer the “Microsplit”
As promised we are now presenting the 8 different timers in the green velvet Minerva filled box. Diameter 51, thickness 19.4 mm. “Base metal” (probably chromed nickel). Fully functional, 9 jewel movement, beating at 360 000/hr! We date it to the 1950s or earlier.
