Wings II keeps the winged brow detail of the base Wings model on a squared metal front, taking a 140mm metal arm to match, which is the spec this compatible pair is cut to. The winged front changes where the hinge sits relative to a plain square frame, so arms cut for a standard square-metal Ray-Ban won't necessarily line up the same way.

Because the winged front is more structurally distinct than a plain square one, it's worth confirming the front itself is undamaged before replacing the arms — a cracked wing detail isn't something a new temple fixes. Where the front is intact and it's just a temple that's bent or has a worn hinge, swapping the arm is the more sensible repair next to sourcing an entire replacement frame in this shape.

Frequently asked questions

My hinge feels loose — will new arms fix that, or is it the frame that's worn?

A new 140mm arm includes its own hinge barrel, so if the wobble is coming from worn threading on the arm side of the 3697, replacing it usually restores a snug, tight fold.

Is it worth buying new arms instead of a whole new frame?

Replacing both arms on the 3697 costs from €26.95 with free worldwide shipping, far less than a new frame, and it's backed by a 3-year warranty against manufacturing defects on the 140mm hardware itself.

Are these official Ray-Ban replacement parts?

These are compatible aftermarket arms, independently produced to match the 3697's hinge and 140mm length. They aren't manufactured or supplied by Ray-Ban, just built to the same measurements so they attach correctly.

Can I replace just one arm, or do I have to buy both?

You can order a single side if only one arm on your 3697 is broken or scratched, or buy the pair if both need replacing — either way they match the 140mm length exactly.
