The green-dial Montblanc 1858 Iced Sea Automatic Date Boutique Edition is reference MB130810. Montblanc lists it as a 41 mm automatic watch with a date display and 300 m water resistance. Those are manufacturer specifications, not independent measurements; the available information does not support firsthand claims about wrist comfort, legibility or finishing.
What is the green Boutique Edition?
MB130810 is the green-dial Boutique Edition in Montblanc’s 1858 Iced Sea Automatic Date collection. Montblanc describes its dial as a glacier pattern made with the gratté-boisé technique. The brand’s listing is the primary reference for this edition’s identity and specifications: Montblanc 1858 Iced Sea Automatic Date Boutique Edition.
Montblanc says the collection’s glacier motif draws inspiration from the Mer de Glace. That design context is useful when considering the textured dial, but it does not establish how the pattern looks under every lighting condition or how it reads on the wrist.
What are MB130810’s listed specifications?
| Specification | Montblanc’s listing for MB130810 |

These values are attributed to Montblanc’s product description; they are not independently measured here. The 300 m rating is a stated water-resistance specification, not evidence in itself of a reference-specific certification document or an inspection of this particular watch.

How is it different from the standard blue MB129369?
The standard blue model, reference MB129369, is a related watch but a different configuration. Montblanc lists that model at 41 mm in diameter and 12.9 mm thick, with a two-tone ceramic bezel and an interchangeable steel bracelet. Those details belong to MB129369 and should not be assumed for the green MB130810.
| Detail | Green Boutique Edition MB130810 | Standard blue MB129369 |
|---|---|---|
| Dial | Green glacier-pattern dial; gratté-boisé technique, per Montblanc | Blue glacier-pattern dial; gratté-boisé technique, per Montblanc |
| Diameter | 41 mm, per Montblanc | 41 mm, per Montblanc |
| Thickness | Not stated on the cited Boutique Edition page | 12.9 mm, per Montblanc |
| Bezel detail | Unidirectional; material and exact configuration not stated on the cited Boutique Edition page | Two-tone ceramic, per Montblanc |
| Bracelet detail | Not established by the cited Boutique Edition page | Interchangeable steel bracelet, per Montblanc |
Montblanc’s pages for the two references are MB130810 and MB129369. Confirm the product reference when comparing listings: collection names and similar case diameters do not make the specifications interchangeable.

What does Montblanc’s 500-hour test establish?
Montblanc describes its Laboratory Test 500 as a program lasting 500 hours, or nearly three weeks. Its service guide says the program simulates daily wear, repeated crown adjustments, different climatic conditions, and normal as well as more demanding use of the watch’s functions. Montblanc also says each watch that passes receives an individual certificate: Montblanc service guide.
This is a description of Montblanc’s testing program, not proof that an individual MB130810’s certificate has been examined. The available sources also do not establish an ISO 6425 certificate for this exact reference. If a particular watch’s test documentation or dive-watch certification matters to a purchase, ask the seller or Montblanc for reference- and serial-specific documentation.

What should you verify before buying?
- Reference and condition: Check that the listing and watch identify as MB130810, rather than the blue MB129369 or an Iced Sea 0 Oxygen model.
- Fit: The listed 41 mm diameter alone cannot predict wrist feel. Thickness, lug-to-lug dimensions, bracelet fit and your own wrist are relevant; the cited Boutique Edition page does not establish all of those details.
- Configuration: Confirm the actual bezel, bracelet or strap, adjustment options and included accessories for the specific watch. Do not infer MB130810 compatibility from another Iced Sea reference.
- Price and availability: These depend on region, seller and date. The available sources do not establish a current local price or stock status.
- Documentation and support: Ask what warranty, service history and any individual test or certification documents accompany the watch.
A boutique retailer also identifies the green Boutique Edition as reference 130810 and corroborates its 41 mm case, MB 24.17 automatic movement and 300 m rating, but this is secondary retail information: boutique retailer listing.
