HYT light module
And then there was light.
As an R&D engineer at Preciflex SA I invented the patented, industry-first light module that illuminates HYT's fluidic watches using mechanical energy. At the push of a button, a dedicated spring barrel spins a micro-generator at incredibly high speed to power light emitting diodes that bring the watch face to life. The module was employed in the limited edition HYT FLOW watch.
