This SR3447 pair shares the same round metal construction, 50mm eye size, and 145mm temple length as the rest of the line, and the UV400 polycarbonate lens comes in the same range of tints, G15 green, brown, grey gradient, brown gradient, or black mirror, so the choice of lens is independent of which frame color you pick.

Gunmetal reads cooler and greyer than a straight black, with a faint metallic quality to the finish that a flat black coat doesn't have. It leans more industrial than the warmer gold options in this line, and pairs naturally with cooler-toned outfits or silver-toned watches and jewelry rather than the warmer accents that suit the gold finishes better.

Frequently asked questions

What material is the frame made from, and how sturdy is it?

The SR3447 is built in durable acetate or metal depending on the Round style, designed to hold up to daily glazing, adjustment, and wear at the optician's the same way any other everyday frame would.

Is there a warranty if the hinge or frame breaks down the line?

Every SR frame, including the SR3447, is covered by a 3-year warranty against manufacturing defects, and at €49.00 for the frame alone plus free worldwide shipping, it's an affordable base for any prescription.

Can I just pop clear lenses in myself without going to an optician?

If you don't need a prescription, you can fit a clear CR39 lens into the SR3447 yourself along the Round rim's groove — this is an independent SR design, not a Ray-Ban or Oakley product — though an optician is recommended for anything requiring correction.

What if the frame doesn't suit my face once I see it in person?

You can try the SR3447 on and return it within 14 days if the Round shape or the 145mm fit isn't right for you, before you've had it glazed with lenses at your optician.
