Seiktona – Chronograph Style Watch
The Seiktona is a custom-built chronograph-style watch designed for bold aesthetics and everyday reliability.
Powered by the genuine Seiko VK63 mecha-quartz movement, it delivers precise quartz timekeeping with a crisp, functional chronograph feel in a clean, sporty design.
Crafted from durable 316L stainless steel, the case and bracelet provide excellent corrosion resistance, long-term durability, and a refined finish. A sapphire crystal ensures strong scratch resistance and clear legibility, making the Seiktona a reliable daily-wear watch with a classic chronograph look.
An automatic NH35 option is available for customers who prefer an automatic movement. Please note that when the automatic option is selected, the chronograph and subdials are decorative and non-functional.
