Powered by a solar quartz movement, the H851, the SNJ025 offers analog time that is synchronized and set by an electronic crown and the supporting digital screen. Using two locking pushers on the left case flank, the screen offers a handful of additional functions, including a digital display of the time, a calendar, local time (second time zone), a chronograph, and an alarm. All of these functions are both very basic and quite useful, with minimal interface between you and the end function itself. Indeed, while the user interface is very easy to understand, it can seem a bit limited as the upper pusher is used as both an “action” button for some functions and as the trigger for the tiny screen’s backlight. So you can have your chronograph, but you can’t easily read it in the dark.
