Meta CEO Mark Zuckerberg has been spotted wearing the Bulgari Octo Finissimo Ultra COSC, the world's thinnest mechanical watch, measuring just 1.7mm in thickness. Priced at $590,000 (around Rs 5 crore), it’s a limited edition with only 20 units produced. The watch features 170 components in its ultra-thin case and is highly accurate, losing only 0.2 seconds per day. Each watch comes with a custom case that stores, sets, and winds it automatically.
