If the arms have gone on your Ray-Ban RX3547V Oval, the two figures to match are 145mm and metal — the length and material of this aftermarket pair, cut for the oval front's hinge position. Oval fronts curve continuously rather than meeting the arm at a flat edge, so a temple built for a square or rectangular RX model won't seat cleanly here.

An oval front isn't quite the same shape as a round one, and the hinge angle reflects that — arms cut for a true round frame can sit slightly off on an oval front even at the same length. That's a fit detail more than a durability one; once the arm is properly seated, oval-metal temples wear the same way any slim metal arm does, mostly at the hinge screw and the tip sleeve rather than along the metal itself.

Frequently asked questions

What if the arms arrive and the hinge doesn't line up with my frame?

Because each pair is listed against a specific model, in this case the 3547, mismatches are rare, but you're covered by a 14-day return window if the mm arms don't align with your hinge.

What material are the arms made from, and will the color match my frame?

The arms are molded in an acetate or metal finish that matches the style of the 3547 closely, though very slight shade variation is possible since they're independently produced as separate aftermarket parts rather than cut from the same batch as the frame.

Are these official Ray-Ban replacement parts?

These are compatible aftermarket arms, independently produced to match the 3547's hinge and mm length. They aren't manufactured or supplied by Ray-Ban, just built to the same measurements so they attach correctly.

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

Replacing both arms on the 3547 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 mm hardware itself.
