New Montblanc Iced Sea 0 Oxygen Watches: Specs, Sizes And Pricing

Montblanc continues to build on the success of its dive watch lineup with the latest additions to the Iced Sea Automatic Date 0 Oxygen collection, introducing three distinctive new references that combine robust diving specifications with fresh materials, textures, and dial executions.

The new releases arrive in 41 mm and 38 mm case sizes, offering collectors a wider range of options while preserving the collection’s signature glacier-inspired aesthetic and professional dive-watch capabilities.

Glacier-Inspired Design Meets Technical Dive Performance

A defining element of the Iced Sea collection remains its richly textured dial, inspired by the surface of glacial ice. This distinctive motif returns across the new models, creating strong visual depth while maintaining excellent legibility.

The 41 mm grey dial version features a striking sfumato glacier-pattern dial, where the textured surface interacts beautifully with light. Large applied hour markers and bold hands, all treated with luminescent material, ensure clear readability in low-light conditions and underwater environments.

Its stainless steel case receives a distressed finish, achieved through a special coating process followed by brushing with a hard mineral material, giving the watch a more rugged and tool-oriented appearance. Complementing the case is a unidirectional rotating bezel with a black ceramic insert, reinforcing the professional dive-watch character.

Mounted on a matching stainless steel bracelet, this reference offers a cohesive and robust look, priced at € 5,300.

Limited Edition 700 with Unique Subfossil Wood Dial

Among the most distinctive novelties is the Montblanc Iced Sea Automatic Date 0 Oxygen Limited Edition 700, which introduces an unusual dial material rarely seen in modern sports watches.

This model features a dial crafted from subfossil wood fragments embedded in clear resin, creating a richly textured surface where every piece is visually unique. Because of the natural composition and arrangement of the wood particles, no two dials are exactly alike, adding an exclusive character to the limited edition.

The watch is housed in a 41 mm stainless steel case and paired with a brown ceramic unidirectional bezel, carefully coordinated to match the warm earthy tones of the dial.

Limited to 700 pieces, this edition is offered on a stainless steel bracelet and priced at € 5,900.

Coral Red Limited Edition in a More Compact 38mm Case

Montblanc also introduces a more compact and vibrant version with the Iced Sea Automatic Date 0 Oxygen Limited Edition 300.

Sized at 38 mm, this model retains the recognizable glacier-textured dial design but presents it in a bold coral red tone that immediately stands out within the collection. The bezel follows the same color theme, with a darker red section marking the first 15 minutes, an essential functional detail for dive timing.

The stainless steel case combines brushed and polished finishes, while its softly curved lugs are designed to enhance wrist comfort and wearability.

Collectors can choose between a matching coral red rubber strap or a stainless steel bracelet, making this reference versatile for both sport and casual wear.

This limited edition is restricted to 300 pieces and carries a retail price of € 4,500.

Shared Technical Specifications

Despite their visual differences, all three new references are built around the same solid technical platform that defines the Iced Sea collection as a capable modern dive watch. Each model offers 300 meters of water resistance, reinforced by a screw-down crown and protected by a sapphire crystal, ensuring durability for both daily wear and underwater use.

At the heart of the watches is the automatic Calibre MB 24.17, based on the Sellita SW200, beating at 28,800 vibrations per hour and delivering a 38-hour power reserve. This proven movement provides reliable timekeeping performance while remaining well-suited to the collection’s sports-watch character.

Another standout feature is Montblanc’s 0 Oxygen construction, a technology designed to eliminate oxygen inside the case. Beyond preventing fogging during sudden temperature changes, this system also helps preserve the long-term performance of the movement by reducing internal oxidation over time.

Depending on the model, the watches are fitted with a unidirectional rotating bezel featuring either a ceramic insert on the 41 mm versions or an aluminium insert on the 38 mm edition. All versions can be paired with an interchangeable stainless steel bracelet equipped with a double-folding clasp and fine adjustment system, allowing for improved comfort and adaptability on the wrist.
