Marathon Black General Purpose Quartz Operating instructions

Hello! I've reviewed the user manual for the Marathon watch WW194004. This document includes instructions on how to set the time and details some of its key features, such as its water resistance and shock-proof capabilities. I understand it also has a stop-second feature and an End-of-Life battery display. I'm ready to answer any questions you may have about this watch.
How do you set the time?

What does it mean when the second hand advances in 4 second increments?

What is the replacement battery?
