The Patravi EvoTec is a special and unique watch because it is the first watch to house the revolutionary movement CFB A1000. It is an innovative movement formulated and produced from scratch in the company’s own workshop. Carl F. Bucherer committed itself completely to the growing Indian market by presenting Mr. Ratan Tata with the unique and charismatic timepiece, a Patravi EvoTec DayDate wristwatch at the Swiss Ambassador’s Award for Exceptional Leadership back in 2011. It further brought home the philosophy of Carl F. Bucherer being an independent, family owned business for 3 generations.
