The Rolex factory in Chêne-Bourg had to be evacuated briefly yesterday afternoon because of what was described as a dangerous chemical reaction.
Many different chemicals and heat processes are used to prevent watch components corroding. Some are recognised as potentially carcinogenic – many are poisonous.
Around 30 had to leave while both internal teams and Geneva firefighters made the workplace safe.
No one was injured and staff could re-enter after about a couple of hours.
