The fresh look and new size set this debut apart: The 41 mm stainless steel case provides for the necessary degree of presence on your wrist, while its clear, no frills design make the Regulator Classic Date an extraordinarily contemporary companion. Its straightforward aura is lent greater impetus through the use of exclusively Arabic numbers and the high-quality, galvanized dial. Fine details such as the guilloché interior of the display for hours and seconds, the hand length precisely coordinated with the scale and the thrilling contrast between matted and polished surfaces provide for an aesthetically pleasing overall image.

In terms of technical refinements, the Regulator Classic Date boasts a date window featuring a magnifying glass. What’s more, it can be perfectly read even in the dark, as the dial and hands are equipped with highlights and inlays made of Super-LumiNova. And you can have fun taking a dip with it, as it is water-resistant up to 10 bar.

With the Regulator Classic Date, Chronoswiss has also selected color and material combinations to create a non-conventional, self-winding watch boasting equal mastery of watchmaking and timeless design. Whether puristic and bright with a dial in galvanic silver, dark with a ial galvanized in matte-black, or rather more unconventionally in deep midnight blue with black accents—this date could turn into a lifelong love.
