Apollo Bio-Metal Dive Mask Titanium with UV420 Lenses

The Titanium Apollo Bio-Metal Mask employs titanium alloy as the material of the metal mask frame. Titanium alloy is known as the highest-quality and expensive metal that has the maximum specific strength among practical metals, about half the weight of iron, and excellent corrosion resistance. Small sized frame can only be realized by only metal frame both the breadth of vision and the field of three dimensional vision for both eyes are the number one in the world.

FLANGE TYPE
At a time of purchase, you can choose the mask flange type from type-A, type-B, type-C and type-D. The color of flange is limited to black only.

UV420 LENS
The multilayer coating on the surface of tempered lens cuts wavelengths of blue through ultraviolet region from approximately 420 nm.

It is widely known that light rays with ultraviolet rays of 380 nm or less are harmful for the eyes and the skin. However, recently it has become apparent that light rays in the wavelength range between 420 nm and 380 nm within the visible ray also cause deterioration and diseases of eyes, such as oxidative stress and reduction of lutein.

For that reason, cuts in this wavelength range is now recommended every where including spectacle lens manufacturers.

More Stylish with UV420
The surface reflection of peach color is added to the multilayer coating, for further enhancing the bio-metal stylish design.
It does not spoil eye contact property underwater in diving since the reflection characteristics change underwater.
On the other hand, on land, it transforms your bio-metal mask to a more stylish and attractive mask in addition to the UV 420 cut.

Carrying Case
The Titanium Apollo Bio-Metal Mask comes with the exclusive carrying case which is extremely durable and waterproof. It protects the bio-metal mask Titanium from any damage during the transportation.

CAUTIONS FOR USE
Please do not polish the coating surface (the outside surface of the mask) with abrasive etc. Also, rubbing with sand etc attached may scratch the coating so please be sure to wipe off moisture with a soft cloth etc. after flushing with running water etc.

Mask Specs

Type-C (inner volume 110cc)

The type-C design is a universal shape that suits everyone the most, and it has been adopted since the introduction of the bio-metal mask. Its merits are soft fit and ease of ear clearing. 

It will ensure an effective wide field of view to the travelling direction in the water as the lens surface plane is set slightly upward.

Type-C is the first launch of the flange in the bio-metal series, and it has been the best-selling design.

The outside surface is matted finish for easy cleaning, preventing adhesion of dirt and Virile appearance. 

Double-lip Structure

A lip is the periphery of the diving mask flange that is in contact with the face. The double-lip Structure has one additional lip toward the inside of the flange in addition to the conventional lip that is structured toward the outside of the flange. The double-lip Structure doubles the total area in contact with the face, consequently reducing the contact pressure on the face and improving the waterproofing.

Advanced double-lip Structure

The “advanced double-lip” structure has a larger arc cross-sectional shape periphery, which gradually weakens the pressure on the outer periphery of the face toward the outside so that it hardly leaves marks on the face.

Stabilizer Structure

The flange of the stabilizer structure wraps the frame around the lower and side surfaces of the frame. This Structure has overcome the weakness of a conventionally shaped flange that tends to bend from the root of the connection portion with the frame. As a result, the stabilizer structure has achieved very stable mounting while the inner volume remains at a minimum.

Twin-curve Structure

The curved circumferential surface effectively uses different curves at the inner and outer surfaces so that the periphery gradually changes the thickness of the cross-section. This Structure optimally controls the amount of the bend and contact pressure of the circumferential surface when mounting.

Wide vertical view

The frame is tilted downward by a further five degrees compared with type A and B, and the lens frame is set as close as possible to the forehead. This Structure has gained a downward field of view and consequently achieves a wider vertical field of view.

Superfit

It is designed to fit more diverse face types compared to other models by selecting material and optimizing the size and shape of the area that fits the face. Its wearing feel is very soft and better to get used to.

Machined Aluminum Alloy Frame.

The luxurious aluminium alloy machined frame delivers accuracy and quality without compromise.

The high-quality frame material with a high degree of accuracy is produced by a luxurious machining process, and the surface thereof is subjected to a plasma coating (part of bio-metal mask pro) or hard alumite processing (aluminium frame) in order to much improve luxury and durability. 

Wide 3D vision with Metal frame –  in the world (Design Patented)

The metal frame attains the width of the centre portion of frames as only 7mm. It feels like a single-lens mask.

Polished by craftsmen in Japan

Metal frame, especially “Migaki (polished) by Craftsman’s hand.
Only underwater mask Crafted in Japan.

Stick to the Lens

Another feature of the bio-metal mask is a wide lineup of lenses.
1-Standard lens made of tempered glass.
2-Polarized lens – laminated – high-quality polarizing plate with the excellent polarizing property.
3-Highly durable bio-AR lens suppresses surface reflections to a minimum by the multilayer coating.
4-Wide range of the off-the-shelf vision corrective lenses made of optical glass.

It is possible to choose a lens that suits you from this lens lineup.

Silicon Anti-adhesive Sheet

The silicon component volatilized from silicone rubber will stubbornly adhere to the inner surface of the mask lens. It is a thing quite difficult to remove. To avoid this, we put the silicon anti-adhesion sheet on the inner surface of the mask lens at the time of manufacturing.

Because of the low coefficient of viscosity with this protection sheet, the sheet can be easily removed and also repeatedly reused. After the mask is used, wash and dry the mask, then put back the protection sheet on the inner surface of the mask lens. It minimizes the occurrence of fogging due to the volatilized silicon even after long-term storage.
