Description
TONA MOD – Chronograph Style Watch
The TONA MOD 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 TONA MOD 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.

FAQ
- What is a Seiko mod?
- A Seiko mod is a modified watch that uses an authentic Seiko movement, combined with third-party high-quality parts. Most of our watches come in stainless steel with sapphire crystal.
- How long will it take to receive my watch?

When we receive the parts, we build the watch the same day and ship it as soon as possible after assembly. Watches in stock from time to time ship faster.
