Seiko Presage Classic Open Heart Watch, SPB471J1
Seiko Presage Classic Open Heart SPB471J1 Men's Watch with Black Dial
The Seiko Presage Classic Open Heart SPB471J1 charms with its vibrant black dial, framed by steel-grey hands and indexes. The partially open dial adds depth to the watch and allows you to observe the movement of the mechanism – a detail that makes the model particularly sophisticated and interesting. The subdued colour scheme and strong, high-quality steel case together create a sturdy and timeless look that works naturally in both casual everyday settings and more formal attire.
Seiko's 6R5J caliber automatic movement with manual winding offers approximately 72 hours of power reserve, a day display, and a stop-seconds function for precise time setting. The double-curved sapphire crystal with anti-reflective coating improves readability in different lighting conditions, and the transparent, screw-down caseback completes the unique look, revealing the movement from the back. In addition, the 100-meter water resistance makes this model a worry-free companion for everyday use.
