Apollo Bio-Metal Dive Mask Titanium with UV420 Lenses
Made in Japan, the Apollo Bio-Metal Titanium mask pairs a corrosion-resistant titanium-alloy frame with UV420-coated tempered-glass lenses and a soft surgical-grade silicone skirt. Choose the regular Type-C or smaller Type-D fit to suit your face.
Choose your skirt fit
- Type-C, 110 cc: regular fit, with more internal room.
- Type-D, 95 cc: smaller fit, aimed at petite-to-medium adult faces.
These are different skirt profiles, so check the seal and nose access as well as the size label. Visit our Hallam store if you would like help comparing the fit.
Titanium construction and Japanese craftsmanship
The titanium-alloy frame combines strength with excellent corrosion resistance and a blast finish. It gives the mask a slim profile and a distinctive appearance, with a softer surgical-grade silicone contact surface against your face.
Tempered glass with a UV420 coating
The lenses combine tempered glass with a multilayer UV420 surface coating. Tempering strengthens the glass; the coating filters ultraviolet and some short-wavelength visible light. The peach-coloured reflection comes from that coating.

How the UV420 coating works
Apollo applies a multilayer coating to the tempered-glass lens surface. The coating reduces the light transmitted through the lens in the ultraviolet region and into the short-wavelength violet end of visible light, up to approximately 420 nanometres. This is the meaning of UV420: the number describes the wavelength range the treatment targets.
For diving and snorkelling, this helps reduce UV reaching your eyes through the lenses while you wear the mask. It is a useful feature for surface swimming, where reflected sunlight can add to exposure. Looking after your eyes also means wearing UV-blocking sunglasses on the boat or shore when the mask is off.
The coating produces a peach-coloured surface reflection. Apollo explains that its reflective appearance changes underwater, helping preserve eye contact with your buddy. Rinse away salt and sand before cleaning, and avoid polishing or abrasive products on the coated outer surface.
Care and storage
Rinse with fresh water after each use and flush away sand before touching the lenses. Use a soft cloth only after grit has been removed. Avoid abrasive cleaners or polishing the coated lens surfaces. Let the mask dry out of direct sunlight and store it with the skirt and strap relaxed.
Adjustable split silicone strap
The wide, split rear section spreads contact across the back of your head and helps keep the strap in place. Adjust the side buckles for a secure, comfortable fit without pulling the skirt tight against your face.
