Chromo Sync is the colour-changing member of the D1 Milano Ultra Thin family: a 40 mm octagonal steel case, 6.2 mm tall, around a light-reactive dial.
Design
The photochromic dial reacts to UV light and moves from blue towards violet outdoors, then settles back indoors, so the watch never looks quite the same twice. Brushed and polished steel surfaces frame the effect.
On the wrist
Inside is a Miyota 1L22 quartz movement, protected by sapphire glass with an anti-reflective coating. The case and bracelet are 316L stainless steel, the bracelet closes on a butterfly clasp, and 5 ATM water resistance covers rain and hand-washing.
