Is the Ratio II Free Diver good for actual diving?

Yes. It is rated to 1000m with a helium escape valve, well beyond recreational dive limits. The sapphire crystal and screw-down crown suit salt water use.

What is the difference between the bracelet and silicone versions?

Same watch head, different strap. The steel bracelet feels heavier and dressier; the silicone strap is lighter and easier to rinse after diving.

Yes, there is a date window on the dial. The listing lists date among its functions.

Is $249 a good price?

It is above the recent low of $199 seen on November 8, 2026, and near the top of the $199–$225 range since November 1. Waiting for a drop toward $200 is reasonable.

Does it need a battery?

No. It runs on an automatic movement powered by wrist movement. If you don't wear it for a few days it will stop and need setting and winding.

How does it compare with a Seiko or Citizen diver?

It offers 1000m rating and sapphire at a price where many Japanese divers give 200m and mineral or Hardlex glass. Japanese brands have longer service networks and more model choices.
