Seiko Business-A 8306-8070 Fluted Bezel White Linen Crosshair Dial

In the 1960s, Seiko introduced the Business-A line, designed for young professionals who wanted practical yet refined timepieces. The Seiko Business-A 8306-8070 from 1967 is a perfect example of this concept, powered by the 8306 automatic movement with a hand-windable 30-jewel caliber based on the 8346 movement.

This model embodies the premium spirit of its era with a cushion shaped case and a refined fluted bezel, giving it a distinguished presence. The silver linen dial features a subtle crosshair pattern, raised baton indices, and sword-style hands, complemented by a clean date only display for balanced elegance.

Inside beats the 8306 automatic movement, operating at 18,000 bph, renowned for its reliability and equipped with a bidirectional quickset date.

This example remains in good working condition with a serviced movement, overall clean dial, light signs of wear on the crystal and unpolished case, which still retains its sharp edges and original brushed finish. The fluted bezel remains crisp, and the case back engravings are clearly visible.

A fine representation of Seiko’s golden era of watchmaking, the Business-A 8306-8070 blends mechanical sophistication and timeless style, making it a worthy addition to any vintage Seiko collection.
