is the key to making these two pieces feel balanced. The 39.9mm SLA017 also came with a typically terrible Seiko steel bracelet which makes the watch feel top-heavy. They left it out for the SLA025, and I see why. The waffle straps are lint-magnets, but feel very comfortable. The SLA025 feels wearable despite the 44.8mm case size (and I usually favour 34mm Rolex cases).
