On the wrist, the SPB313 shines. The curvature of the cushion case hugs the wrist phenomenally and I can't help but think that the extra thinness makes a non-negligible difference here. There's a ton of depth under the curved sapphire crystal, accentuated by the white dial that stands out, not only contrasted against the black
link bezel but in a world of black-dialed divers.
