What distinguishes it
Look beyond the reference.
Miyota’s current product page specifies a 5.10 mm height and nominal five-year battery life. It also emphasises the pusher’s click feel, showing that tactile character is not exclusive to mechanical chronographs.
For the enthusiast
Read the reference with a zero: 0S20. The 24-hour display is distinct from the elapsed-minute register. Compare its operation and layout with TMI VK63 rather than assuming every quartz chronograph uses the same reset mechanism.
