Japanese brand Seiko applies a 41mm bezel-less case design in titanium, reducing weight by approximately 40 percent compared to steel while maintaining the collection’s faceted geometry. Each reference features a distinct dial colour, including [purple, gray, and black](https://www.trendhunter.com/trends/edo-purple), with patterns combining horizontal lines and radiating textures inspired by Tokyo’s urban skyline. All three models are powered by Seiko’s automatic Caliber 8L45 movement, offering a 72-hour power reserve and accuracy rated at +10 to -5 seconds per day. The movement is visible through a sapphire caseback finished with a wave pattern across the rotor and bridges. Each watch is fitted with an integrated [titanium bracelet](https://www.trendhunter.com/trends/ming-3706) featuring a three-fold clasp, alongside 100 metres of water resistance and Lumibrite on the hands and markers for visibility in low light.
