MILUS Tirion Triretrograde is carbon dial arranged on two levels, with reflections that make the blackened surface seem to shimmer. The openworked part reveals a bit of the movement, some rubies, the blackened bridges holding the watch's famous seconds complication, which is held in place by blued screws, the harbingers of mechanical watchmaking performed according to the strictest rules of the art. This latest incarnation of the Tirion TriRetrograde is an ode to contrasts made to draw the eye. The fine bezel and generously dimensioned sapphire crystal show off a complex dial. The hands are edged in red with a crest of luminescent mass. Everything is designed for perfect legibility of time even in the dusk, and, naturally, to show the lighthearted dance of the seconds hands. Indeed, while the minutes and hours tick away at a regular rhythm, the three hands in the center share a minute-long trip over three 20-second retrograde segments. This is a unique and playful choreography of time. Encircling this dynamic complication, the even hours appear in Arab numerals with bar indices for the odd hours. At 4.30, an aperture discreetly provides the date. The steel case is coated with polished DLC, giving it a ceramic-like look. It fits snuggly onto the wrist, belying its 45-millimeter diameter. The crown integrates easily into these elegant lines. Inside the case is a robust automatic Swiss ETA 2892 caliber that promises a power reserve of at least 40 hours. This Tirion TriRetrograde comes on an alligator bracelet that harmonizes well with the exceptional timepiece: it is in sleek black with red stitching.
