Does it have a screw-down crown?

Yes. The crown screws down, which helps with its 200 m water resistance rating.

Is the bracelet easy to change?

Our take on the Orient Men's Kamasu Blue Automatic Sapphire Diver Watch - RA-AA0818L39B

The Orient Kamasu is a mechanical dive watch with an in-house automatic movement, a sapphire crystal and 200 m water resistance. Its blue dial, rotating dive bezel and stainless steel case give it the look of far costlier divers. It suits buyers who want a real automatic diver without paying Swiss-brand money. Against rivals like the Seiko 5 Sports and the Citizen Promaster, the Kamasu stands out for its sapphire crystal and in-house movement, though its bracelet and lume draw more complaints.
