Care Instructions

Water & Moisture: Your hand-assembled Watch Mod should be considered splash-resistant only. Never submerge your watch. Always remove it before showering, swimming, or using saunas/hot tubs. Ensure the crown is always secured.

Daily Cleaning: After wearing, gently wipe the case and crystal with a soft, dry microfiber cloth to remove residue. For metal bracelets, use a mild soap and water occasionally, and dry immediately. Keep leather straps dry.

Protect the Movement: Protect your watch from strong impacts, powerful magnetic fields (which affect accuracy), and temperature extremes. Do not leave it in direct, intense sunlight or freezing conditions.

Long-Term Care: Wind your automatic Watch Mod weekly if it is not worn daily. To maintain optimal performance, plan for a full movement service and gasket check by a professional watchmaker every 3 to 5 years.
