The result is a deep, dark metallic surface that sits somewhere between matte and mirror, and it photographs incredibly well.<\/p><h2 class=\"wp-block-heading\" id=\"h-a-dial-that-plays-hide-and-seek\">A Dial That Plays Hide and Seek<\/h2><p>The commitment to the all-black theme runs deeper than the case. The dial is black. The appliques are black. The hands are black.
