It uses a drum-type flip display mechanism that is different from the traditional single-chip page flip structure. When the digital page is switched with the minute, it will make a gentle mechanical flipping sound. There is a 50Hz/60Hz frequency switching switch on the back, which can adapt to the power grid frequency standards in different regions. It also integrates an alarm and a warm orange backlight function. The numbers turned out in a dark light environment will reveal a soft amber halo. The beige matte shell has small spots left by slight age and traces of normal use, and there are no structural cracks or bumps and damages; it is powered by 100v, and the page turning mechanism runs smoothly. It comes with the original power cord and no original packaging box.
