How does the two crowns and pushers work on my LYJ II watch ?Updated a year ago

Here is how the 2 crowns function:

60-Minute Timer on Subdial:

The 60-minute timer on a subdial is often used as a stopwatch. This subdial allows you to measure elapsed time up to 60 minutes

24 Hour Clock on Subdial:

• The 24 hour timer subdial correlates to the main time.  For example, if the time is 8:00PM, then the 24 hour subdial will display 20 which essentially is 20:00 with 24 hour time.  It’s helpful at allowing you to quickly read AM/PM at a glance. 

Note
- The top pusher and bottom pusher on the watch serves as a stopwatch function.
- There is no date dial on this watch.
- The watch does not have an automatic hand movement.
