If your chronograph isn't returning to zero on your MIYOTA 0S20 watch after resetting or a battery change, here's how to fix it, according to the MIYOTA 0S20 Caliber Watch Movement Instruction Manual: First, pull the crown out to the second position. Next, press button "A" to begin resetting the chronograph second hand. You can quickly advance the hand to zero by holding down button "A". Once the chronograph hand is at zero, push the crown back into its normal position. Be patient; ensure the chronograph hand completely reaches zero before you push the crown back in. Following these steps will reset your chronograph function on your MIYOTA 0S20 watch. Always consult your watch's specific instruction manual for model-specific details.
