Who should buy which.
The Sport Automatic Blue (NH7530-52M): A buyer who wants sapphire, 100 m water resistance and a mechanical movement for under $400. Skip it if you prefer slim or small watches; the Citizen NH8350 or a 38 to 40 mm diver suits you better.
The 5 Sports: A first-time automatic buyer drawn to a larger sports-watch silhouette.
Before you order.
At 42 mm and 13 mm thick it is a substantial watch; check it against one you wear. The reserve is a typical 42 hours, so it will stop if left off the wrist over a weekend.
This is a sports watch, not a substitute for a certified diving instrument. The official US store currently lists it as sold out.
