Author POV

Two hundred metres of water resistance is the highest rating in this whole stack of Grand Seikos I've catalogued, and it repositions this Sport reference — SBGE255 — away from the dress-adjacent Elegance and Heritage lines entirely: 40.5mm steel case, blue dial, steel bracelet, Spring Drive movement with the usual glide-motion seconds and power-reserve display. On my durability axis, 200m is genuinely usable territory — swimming, not just rain — which most of the Spring Drive catalogue doesn't clear. It's a reminder that 'Sport' in Grand Seiko's naming isn't just cosmetic; the water-resistance number backs it up for once.
