Turn the Digital Crown to set the weight, turn again to choose the karat, confirm the synced spot price and read the estimate. Subtle haptics confirm each step. The watch keeps your last synced prices, so it works even when your iPhone is out of reach. WIDGETS Keep your saved gold price one glance away with Lock Screen and Home Screen widgets: spot price, a quick value for your last calculation and a per-gram table for every common karat. A Control Center button opens the calculator directly. OFFLINE ENGINE Every calculation runs on your device with exact decimal arithmetic — it works in Airplane Mode. KaratMaster never downloads prices: the spot price is always the value you enter, shown with the time you last changed it. TRANSPARENT MATH See exactly how the result is produced: 10.00 g × 75.0% = 7.500 g pure gold 7.500 g × spot price = gross value gross value × payout % − deductions = estimated value Deductions are always listed separately — never hidden in the final number.
