2. התקנה
2.1 טעינה ראשונית
Upon receiving your watch, ensure it is fully charged by exposing the dial to a bright light source (natural or artificial) for several hours. The Eco-Drive movement stores energy in a power cell, allowing the watch to operate for extended periods in darkness once fully charged.

4.1 ניקוי
Regularly wipe the watch case and sapphire crystal with a soft, dry cloth to remove dust and smudges. For the brown leather strap, use a slightly damp cloth and mild soap if necessary, then dry thoroughly. Avoid harsh chemicals or abrasive materials that could damage the watch or strap.
4.2 עמידות במים
This watch is water resistant to 100 מטר (333 רגל). It is suitable for swimming and snorkeling but not for scuba diving. Always ensure the crown is pushed in completely before any water exposure. Do not operate the crown or pushers while the watch is wet or submerged.
4.3 Light Exposure and Storage
To maintain optimal performance and ensure continuous operation, expose the watch to light regularly. When not in use, store the watch in a location where it can receive ambient light, or in a well-lit area, to prevent the power cell from depleting.
