What Does Our “%” Logo Mean in Seiko Mod Watches?

Precision, Original Design, and Responsible Mod Watchmaking

In the world of Seiko mod watches and custom mod watches, branding is often loud.
Logos are oversized, stories are exaggerated, and borrowed identities are everywhere.

Watchbrick chose a different path.

Our “%” logo is intentionally minimal — not because we lack identity, but because we believe a well-built custom mod watch should be defined by precision, process, and integrity, not by imitation or marketing noise.

This article explains what the “%” logo really means, how it connects to NH35 and VK63-powered mod watches, and why Watchbrick takes a very different approach to design and legality in the Seiko mod space.

A Logo Designed for Mod Watches — Not for Hype

A mod watch is fundamentally different from a mass-produced factory watch.

Whether it’s powered by an NH35 automatic movement or a VK63 mecha-quartz chronograph, every mod watch relies on:

• Mechanical tolerances

• Manual assembly

• Careful adjustment, not automation

In watchmaking, perfection does not exist.
What exists is control within acceptable margins.

That is what the “%” symbol represents.

It stands for:

• Measured precision

• Engineering honesty

• Performance within tolerance

The logo reflects how real watches are built — not how they are marketed.

What “%” Means in Mechanical Watchmaking

Every mechanical or mecha-quartz movement operates within defined ranges:

• Daily rate variance

• Beat error

• Amplitude stability

An NH35 movement, for example, is not designed to be perfectly accurate to the second. It is designed to be reliable, durable, and serviceable within a controlled performance range.

The same applies to VK63 movements, which combine quartz accuracy with a mechanical chronograph feel.

The “%” logo acknowledges this reality.

Rather than pretending mechanical watches are flawless, Watchbrick embraces transparent, measurable performance.

Why Watchbrick Avoids Traditional Logos and Borrowed Branding

In the Seiko mod market, it is common to see watches that rely heavily on familiar logos or visual cues to create perceived value.

Watchbrick deliberately avoids this.

The “%” logo communicates:

• No borrowed legacy

• No imitation branding

• No claim of affiliation

It keeps the focus where it belongs:
on movement quality, assembly precision, and original design.

The Problem With Off-the-Shelf “Seiko” Logo Dials

In the broader mod watch market, it is easy to find dials printed with a Seiko logo, sometimes sold online for as little as USD $5.

While widely available, these dials carry serious legal and ethical risks.

Seiko is a registered trademark.
Using Seiko-branded dials in watches that are not official Seiko products creates clear trademark infringement, regardless of how common these parts appear in online marketplaces.

This is one of the most misunderstood issues in the Seiko mod world.

Availability does not equal permission.

Why Watchbrick Uses Fully Custom Dials Instead

At Watchbrick, we intentionally do not use Seiko-branded dials — even though they are cheap, accessible, and widely circulated.

Instead, every Watchbrick custom mod watch uses a fully custom-manufactured dial, developed directly with our partner factories.

This process includes:

• Original dial layout design

• Custom selection of applied indices (hour markers)

• Font spacing and proportion adjustments

• Careful colour tuning under different lighting conditions

• Multiple sampling and revision rounds

Whether a watch uses an NH35 automatic movement or a VK63 chronograph, the dial is treated as a functional component, not just a visual surface.

Custom Dial Development Is Hard — and Intentional

Creating a proper custom dial is time-consuming and costly.

It requires:

• Tooling and mould development

• Physical samples, not just digital renders

• Colour matching beyond screen accuracy

• Rejected batches and rework

This investment is significantly higher than buying generic logo dials — but it ensures that every Watchbrick mod watch is:

• Legally compliant

• Original in identity

• Built with long-term credibility

Original design is not the easy path.
It is the responsible one.

% as a Symbol of Craft, Control, and Accountability

Every Watchbrick custom mod watch is made to order.

Each build involves:

• Individual movement inspection

• Manual hand installation and alignment

• Case fitting and sealing by hand

The “%” logo reflects this mindset:

Quality is not absolute — it is achieved through control.

It is a reminder that real craftsmanship happens within margins, not slogans.

Why This Matters to the Wearer

For the customer, this approach means:

• No trademark grey areas

• No misleading branding

• No confusion about what the watch represents

You are not wearing a watch that imitates a factory product.
You are wearing a purpose-built custom mod watch, assembled by hand, powered by genuine TMI NH35 or VK63 movements, and finished with a dial designed exclusively for this build.

Final Thoughts: Precision Over Imitation

The “%” logo is not a branding trick.
It is a design decision rooted in engineering logic and responsibility.

It reflects:

• The realities of mechanical watchmaking

• The controlled tolerances of NH35 and VK63 movements

• A commitment to originality over shortcuts

In a market full of borrowed identities, Watchbrick chooses restraint — and lets the work speak.
