Montblanc Iced Sea 0 Oxygen 38mm: ISO 6425 Certified with Advanced Technology
Montblanc Expands Iced Sea Collection with ISO 6425 Certified 38mm Models
At Watches and Wonders 2025, Montblanc unveiled a significant addition to its Iced Sea collection: the Montblanc Iced Sea 0 Oxygen 38mm. According to aBlogtoWatch, these new models maintain ISO 6425 certification while introducing advanced 0 Oxygen technology and new dial options.
Understanding ISO 6425 Certification
ISO 6425 is the international standard that defines the requirements for dive watches. The Montblanc Iced Sea collection has been certified to this standard since its introduction in 2022, ensuring these timepieces meet professional diving requirements.
0 Oxygen Technology Innovation
Montblanc's 0 Oxygen technology eliminates all oxygen from inside the case, providing several benefits:
- Prevents fogging due to sudden temperature changes
- Protects internal components from oxidation
- Enhances long-term durability and performance
- Each watch comes with a certificate verifying the technology
Starting April 2025, Montblanc will integrate 0 Oxygen technology into all newly produced Iced Sea models. Previous edition owners can upgrade their watches through Richemont service centers.
New Dial Colors and Techniques
The 38mm models introduce two new dial colors featuring the gratté-boisé technique:
- Glacier White (134024) - First white dial in the Iced Sea collection
- Glacier Blue (134022) - Features sfumato effect for soft color transitions
According to aBlogtoWatch, this intricate technique takes four times longer to complete than a standard dial, requiring over 30 distinct steps to achieve its frozen aesthetic.
