Displaying hours and minutes via central hands with luminescent fill, the blue dial with Roman numerals and luminescent indices also features small seconds at nine o'clock and date aperture between the four and five o'clock positions, while the chronograph function is accentuated with red and features central seconds, 30-minute counter at three o'clock and 12-hour counter at six o'clock. Visible through the inviting transparent back of the 43mm case, the self-winding UN-150 caliber boasts 25 jewels and builds up a power reserve of 48 hours. Featuring a fluted bezel and screw-down crown and ensuring 100m water resistance, the polished stainless steel case is mounted onto a blue rubber strap with titanium inserts and a deployment clasp.
