How is The Samurai Series Different from Diver/Prospex?

Seiko is known for producing some of the world’s best dive watches, and three of its most popular models are the Samurai, Diver, and Prospex. While each of these watches shares many similarities, there are also several key differences that set them apart.

In terms of build quality, all three watches are constructed with high-quality materials and designed to withstand the rigours of underwater use. However, the Samurai’s angular case and bezel give it a unique appearance that sets it apart from the more traditional round case and bezel of the Diver and Prospex.

When it comes to the target audience, the Seiko Diver is designed to appeal to a wide range of watch enthusiasts, from casual wearers to professional divers. The Prospex, on the other hand, is geared towards more serious divers who require a watch with advanced features like a helium release valve and a depth gauge. The Samurai, meanwhile, sits somewhere in between, offering a balance of style, durability, and functionality that appeals to both serious divers and casual wearers. One thing that sets the Samurai apart from the other two watches is its distinctive bezel design, which resembles the armour of a samurai warrior. This gives the watch a unique and eye-catching appearance that is instantly recognizable.
