Setup, Compatibility & Care
To ensure your Montblanc Iced Sea remains in peak condition, wind the crown periodically if the watch has not been worn for more than a day to keep the movement active. Because this watch is a specialized zero-oxygen model, all maintenance, including battery changes or internal adjustments, must be performed by an authorized Montblanc service center to preserve the hermetic seal and the oxygen-free interior. Rinse the watch with fresh water after exposure to saltwater to prevent salt crystallization, and avoid exposing the sapphire crystal to high-impact surfaces to prevent scratching.
