Seiko Unisex Presage Classic Series SPB523J1

Seiko Presage Classic Series SPB523 – Compact Automatic with 72-Hour Power Reserve

The Seiko Presage Classic Series SPB523 combines classic design with modern mechanical watch technology. The compact 36mm stainless steel case, the high-quality automatic movement, and the balanced proportions make this model a versatile unisex watch for both men and women.

Compact 36mm Stainless Steel Case

With a case diameter of 36mm, the Seiko Presage SPB523 wears particularly well-balanced on the wrist. The case length of 41.4mm and the height of 12.5mm emphasize its compact proportions.

The stainless steel case is treated with Seiko's Super-Hard-Coating, which makes the surface more resistant to wear and tear.

Automatic Movement Caliber 6R51

Inside, the mechanical Seiko Caliber 6R51 with automatic winding is at work. The movement can also be hand-wound.

The power reserve is approximately 72 hours, allowing the watch to run for about three days after being fully wound. The movement features 24 jewels and a hacking seconds function for precise time setting.

Sapphire Crystal and Exhibition Case Back

The dial is protected by a dual-curved sapphire crystal. An anti-reflective coating on the inside improves legibility and reduces distracting reflections.

The screw-down exhibition case back allows a view of the mechanical movement.

Stainless Steel Bracelet with Folding Clasp

The stainless steel bracelet harmoniously complements the classic design of the Presage. The lug width is 18mm, and the maximum bracelet circumference is 195mm.

The folding clasp with a push-button release on both sides ensures a secure fit and comfortable opening.
