• Time setting: Pull the crown to the second position to adjust the hour and minute hands. The MT5602 has no date complication, simplifying setting.
• Dive timing: Align the bezel’s red triangle with the minute hand before descending; the elapsed time can be read on the 60‑minute scale.
• Maintenance: Rinse with fresh water after exposure to salt or chlorinated water; avoid extreme temperature changes; service every 5–7 years with Hourglass Emporium to ensure long‑term reliability.
