Frame Profile and Silhouette

The Ray-Ban RB3689 gold aviator sunglasses with brown gradient lenses represent the Aviator Metal II  a direct evolution of the original aviator silhouette that has remained one of the most widely recognised frame shapes in sunglasses. The teardrop lens shape drops from a slim double brow bar, wider at the top and narrowing toward the lower outer corners, creating the characteristic downward sweep of the aviator profile. Furthermore, the full-rim metal construction encircles each lens completely, giving the frame a clean and continuous outline without the open lower wire common on semi-rimless aviator variants.

Colour and Lens Appearance

The 914 Arista frame colour presents as a warm gold-tone metal finish across the entire front frame, brow bar, and temple arms. The gold tone is consistent and mid-warm in character — neither a deep yellow-gold nor a pale champagne and carries a smooth, polished surface. The 51 lens code confirms a light brown gradient  the lens tone transitions from a medium brown at the upper portion to a near-clear finish at the lower edge. Consequently, the gradient reads as warm and amber-adjacent in direct light, shifting to a lighter, more neutral tone toward the bottom of each lens.

Temple and Hardware Detailing

The temples extend from the frame front in the same gold-tone metal as the brow bar, running as slim, straight arms before transitioning into tortoiseshell acetate temple tips. The nose pads are separate adjustable silicone-style pads mounted on metal stems  a standard aviator construction clearly visible in the front product image, distinct from the integrated acetate bridges used on the Marc Jacobs optical frames in this range.

Size and Fit Reference

The RB3689 in 58mm lens width sits at the larger end of the standard aviator size range. In comparison, the same model is also available at 55mm — the 58mm produces a frame that sits wider and covers more of the face vertically due to the teardrop depth. The 14mm bridge is narrow, which is consistent with the aviator construction where the double brow bar spans above rather than between the lenses. Buyers familiar with the RB3025 Original Aviator will find the RB3689 Aviator Metal II closely related in proportion and silhouette.

Everyday Use

The RB3689 in gold with brown gradient suits a wide range of outdoor settings and lens suits natural daylight conditions. In particular, the brown gradient lens tone works well in variable light the darker upper portion reduces overhead glare while the lighter lower area maintains visual clarity for activities requiring downward sight lines such as driving or walking.
