FAQ

1. Is this chronograph second wheel an original CITIZEN/MIYOTA genuine part?
Yes. It is an original MIYOTA factory part, made in Japan.

2. Which movements is this chronograph second wheel compatible with?
It fits MIYOTA 6S10 and 6S20 quartz chronograph movements—they share the same base caliber (15 ligne, 4.90mm height). The primary difference is date position: 6S10 has a date at 3 o’clock, while 6S20 has the date at 4:30. The 6S20 offers 1/20 second chronograph precision, while the 6S10 offers 1/5 second precision.

3. How does this part relate to the 1/20 second counter and chronograph minute counter?
The 6S10/6S20 series features multiple chronograph subdials: the 1/20 second chronograph hand at 12 o’clock and the 60-minute totalizer at 3 o’clock. This part typically drives one of these subdials—verify the 12H or 3H marking on your old part.
