Under the rider at 6 o'clock, #HYTWatches has concealed two LEDs. Once activated, they flood the entire #H4Metropolis dial with blue light. At night, the yellow fluid is energised by this light source, becoming perfectly visible. Did we mention that this #H4Metropolis #watch is a first for #HYT and for #watchmaking ? by hytwatches
