The Montblanc Iced Sea Automatic Date in grey is a high-performance diving watch designed for adventure seekers who appreciate fine Swiss craftsmanship. Its standout feature is the glacier-patterned dial, created using the traditional gratté-boisé technique, which provides a sophisticated look suitable for both professional diving and daily wear. While its robust build is perfect for aquatic environments, potential owners should note that its specialized 41mm case and diver-focused design may feel substantial for those who prefer thinner, dress-style watches.

No, this is an automatic mechanical watch powered by the movement of your wrist. It does not require a battery.
Yes, the watch features an interchangeable system that allows you to change straps without any tools.
It is water-resistant up to 300 meters (approx. 1,000 feet).
The pattern is inspired by the textures found in the Mer de Glace glacier.
Always ensure the crown is fully pushed in and screwed down before entering the water.
If the watch has not been worn for several days, it has likely exhausted its power reserve. Manually wind the crown clockwise 20-30 times to restart the movement.
Pull the crown to the first position and rotate it to advance the date. Avoid changing the date between 9:00 PM and 3:00 AM to prevent damaging the internal date-change mechanism.
If you notice fogging, the seal may be compromised. Pull the crown out to stop the movement and take the watch to an authorized service center immediately.
To ensure the longevity of your timepiece, it is recommended to have the watch professionally serviced every 3-5 years. When setting the time and date, ensure the crown is fully screwed down after adjustment to maintain the 300-meter water resistance seal. If you have been swimming in saltwater, rinse the watch with fresh water and dry it with a soft cloth to prevent salt buildup. The interchangeable strap mechanism allows for quick swaps; simply press the release catch on the underside of the lugs to detach the strap. Avoid exposing the watch to intense magnetic fields, which can affect the accuracy of the mechanical movement.
