How to use the Beachmaster's Mission Timer

This short animation covers how to use the different timing complications, including setting the time, the GMT and then setting and using the patented Mission Timer to count down and up in 12 hour sections.

Please note:
This animation covers the Automatic Beachmaster functionality. The functionality for the quartz Beachmasters is the same with two small differences: When setting the GMT hand it moves smoothly rather than jumps, and this is controlled by turning the bottom crown in an anticlockwise direction.
