### **Metric Breakdown:**

- **Brand (10% Weight): 8.5/10**

Seiko is widely respected for its robust craftsmanship and history of innovation, particularly in the realm of dive watches. The Prospex series is recognized as one of the best value propositions in the dive watch category, offering serious diving functionality at an accessible price point.

- **History & Innovation (10% Weight): 8.0/10**

The SPB213 is part of Seiko’s long-standing legacy in the dive watch world, originally drawing inspiration from Seiko's 1965 diver watch. While it doesn’t introduce groundbreaking innovations, the model continues Seiko’s tradition of reliable and well-made diving watches that reflect decades of refinement.

- **Rarity (10% Weight): 7.5/10**

This model is part of Seiko’s regular production, making it readily available, but it holds appeal due to its position as a high-quality mid-range diver’s watch. It doesn’t have the exclusivity of a limited edition or rare model, but it is appreciated by enthusiasts for its functional and aesthetic qualities.

- **Material (10% Weight): 8.5/10**

The SPB213 is constructed from stainless steel with a super-hard coating, which ensures it can withstand rugged conditions. The sapphire crystal with anti-reflective coating on the inner surface adds to its durability, and the overall quality of materials is above average for its price range.

- **Movement (10% Weight): 8.2/10**

The watch is powered by Seiko's in-house automatic caliber 6R35, which features a 70-hour power reserve. While not as high-end as some Swiss counterparts, the 6R35 is known for its reliability and decent precision for a watch in this price category.

- **Complications (10% Weight): 7.5/10**

The SPB213 is a straightforward dive watch with a date function. While lacking any additional complications like a GMT or chronograph, it performs its core diving function well.

- **Functions (10% Weight): 9.5/10**

The watch excels in its intended purpose as a dive watch, offering 200 meters of water resistance, a screw-down crown, and a unidirectional rotating bezel for underwater timing. It also has excellent lume on the hands and markers, powered by Seiko's proprietary Lumibrite technology, making it highly legible in low-light or underwater conditions.

- **Dials & Design (10% Weight): 9.0/10**

The design of the SPB213 stands out with its blue dial and gold accents, which is both functional and stylish. It combines classic diver elements with a modern aesthetic, making it versatile enough for both casual wear and professional diving use. The dial layout is clear and easy to read, with Seiko’s typically excellent attention to detail in its finishing.

- **Versatility (10% Weight): 8.8/10**

While primarily a dive watch, the SPB213’s polished case and elegant design allow it to be worn in more formal settings as well, providing good versatility for a sports watch. However, its large size may not appeal to those with smaller wrists or those looking for a slimmer option.

- **Cohesiveness (10% Weight): 8.7/10**

The design, movement, and functionality of the Seiko Prospex SPB213 are highly cohesive, aligning with Seiko's goal of producing robust, functional, and affordable dive watches. The watch integrates well within the broader Seiko Prospex lineup, offering a balance of form and function.
