Platinum Watch

The Platinum Watch is a high-tier Watch type. The Gold Watch is an alternate to it. When equipped in an accessory slot or simply held in the inventory, a clock will appear in the upper-right corner of the playing screen, revealing the in-game time accurate to the last minute. A minute of Terraria game time is equivalent to a second of real-world time. It is required for crafting the Cell Phone, GPS, and 1 Second Timer.
