| Reference | Configuration | Bezel detail | US listed price |
|---|---|---|---|
| MB134023 | Blue dial, blue interchangeable rubber strap | Bi-colored blue anodized aluminium insert | $4,300, per Montblanc US |
| MB134022 | Blue dial, bracelet | Bezel insert detail not stated on the cited page | $4,500, per Montblanc US; bracelet has a fine-adjustment system |
Montblanc also lists white-dial and black 38 mm variants. Their exact references and configuration details are not established here, so check the relevant product page rather than assuming the blue models’ specifications or prices apply to them. The available documentation does not establish a movement or water-resistance difference between the two blue references.
What does “0 Oxygen” mean in this watch?
Montblanc describes the stainless-steel case as “totally devoid of oxygen.” That is the supported claim: the brand identifies oxygen-free construction as a case feature. Its product information does not explain the manufacturing method or quantify any resulting change in fogging, oxidation, reliability or service life. Those outcomes should not be treated as proven benefits on the basis of the phrase alone. Montblanc product information

How is the dial designed?
Montblanc says the dial takes inspiration from the Mer de Glace glacier and uses a technique called gratté-boisé to create its textured glacier pattern. The design ties the watch to the alpine subject behind the Iced Sea name; it is a visual inspiration, not a claim about the watch’s diving performance. Montblanc product information

What should a buyer verify before ordering?
- Confirm the reference number and whether the listing is for a rubber strap or bracelet; the blue configurations have different references.
- Check the current price and stock with Montblanc or the seller, since the cited US prices are snapshots and availability can change.
- For white- or black-dial models, verify that specific reference’s details instead of transferring specifications from the blue references.
- If the oxygen-free case claim is central to your choice, distinguish Montblanc’s stated feature from performance effects that its cited product information does not quantify.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
