PUR Adhesive for Assembling Smart Watches

Market Trend for Smart Watches

According to the Global Smartwatch Model Tracker, despite the continuation of inflation and geopolitical unrest in 2022, worldwide shipments of smartwatches increased by 12% this year. And to make things even more exciting, thanks to their rapidly expanding local market, India's smartwatch market grew by 171% YoY in Q3 of 2022, becoming the largest smartwatch market worldwide!

When it comes to smartwatches, the entry-level model has helped the Indian market tremendously since it has less expensive costs and lighter operating systems. Nevertheless, due mostly to their higher selling costs, High-Level OS smartwatches make roughly ten times as much money as simple smartwatches.
