A pleasant and (at least by me) unexpected introduction is the new Zenith Elite 6150, a very thin & elegant 42mm time-only watch.
"This new automatic Elite 6150 calibre is the contemporary version of the famous Elite base movement developed in the early 1990s – an ultra-thin calibre that earned the title “Best Movement of the Year” when presented at the Basel Fair in 1994." [Press Kit, slightly modified]
"In response to the demands of our times, the Zenith engineers and developers have chosen to enhance its performance, as well as its versatility by means of a minimum 100-hour power reserve, a broader 30 mm diameter, along with a central sweep-seconds hand." [Press Kit, slightly modified]
"They have also been careful to preserve the exceptionally slender nature of a movement measuring a mere 3.92 mm thick! Driven by the new Elite 6150 calibre, the Elite 6150 model is distinguished by its classicism and its understated elegance. Its slim 42 mm-diameter case frames a pure, cambered dial punctuated by sleek, graceful hands." [Press Kit, slightly modified]
