The center crown, on the
link case next to three o'clock, cycles through the modes, including time, a second timezone, an alarm, and a chronograph. While you do have the choice of an hourly chime, and yes you can set the second time
link to any time you
link want (meaning you can account for non-full hour GMT offsets, like Newfoundland or Sri Lanka) the Momentum UDT does not have a backlight for the digital screen.
