The Montblanc Iced Sea 0 Oxygen Deep 4810 is a 43 mm titanium dive watch with a COSC-certified automatic movement, approximately five days of power reserve and a stated water resistance of 4,810 metres. Montblanc also says it conforms to ISO 6425. Its name and depth rating make it an extreme-specification diver, but the number alone does not determine whether it is the right watch for a particular wearer or use.
What the Iced Sea 0 Oxygen Deep 4810 is
Montblanc positions the Deep 4810 within its Iced Sea collection. The official US product page identifies the model as reference MB133268; Montblanc’s Romanian page uses reference MB135634 for a watch with the same model name. Those reference numbers are market-specific identifiers in the cited listings, so check the exact regional product page before comparing or ordering.

Glacier-inspired design
The blue sfumato dial has a glacier pattern that Montblanc links to the Mer de Glace, which the brand describes as the largest glacier in the Mont Blanc Massif. Montblanc says it creates the texture using the gratté-boisé technique, scraping the dial surface with a selected piece of wood. The detailed listing describes white luminescent rhodium-coated Arabic numerals and indexes.
The case back carries a three-dimensional relief depicting a diver beneath ice. Montblanc also describes the collection strap as interchangeable and equipped with a fine-adjustment system; check the listing for the particular reference and market for the included configuration.

What “0 Oxygen” means
Montblanc says its Zero Oxygen technology is intended to reduce fogging caused by temperature changes, prevent component oxidation and preserve movement oils. These are manufacturer claims, not independent test results established by the cited product pages.
How to assess the depth rating
The 4,810 m / 481 bar figure is Montblanc’s stated water resistance, while the brand separately states that the watch conforms to ISO 6425. These specifications describe the watch as presented by its manufacturer; they should not be treated as a recommendation to take it to that depth. For a comparison with another diver, look beyond the largest depth number.
