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 Tsuyosa Automatic Orange Dial (NJ0151-53Z): A buyer who wants a 40 mm automatic bracelet watch with a saturated orange dial, sapphire crystal and a date. Choose another reference if you need a quiet dial, a conventional strap connection, a published lug-to-lug measurement or warranty coverage that is already clear.

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.

Citizen lists WR50 / 5 bar and describes still-water swimming, so we would choose a more purpose-built model for diving. The official page does not publish lug-to-lug for the integrated bracelet; compare its proportions with a watch you already wear.
