Is radium used in watches today?

I'm curious to know if radium, a radioactive element once touted for its luminescent properties, still finds its way into the intricate mechanisms of watches in today's modern era. With the advent of new technologies and safety regulations, has the use of radium in watches been phased out? Or does it still hold a niche in certain luxury or vintage timepieces? Understanding the answer to this question could provide insight into the evolution of watchmaking and the safety considerations surrounding the use of potentially harmful materials.
