Terra Gaia

# Terra Gaia

## Product Overview

Terra Gaia captures the striking beauty of natural azurite, with deep blue tones and rich mineral patterns that flow uniquely across every dial.

Some dials evoke winding rivers, some resemble the vast ocean, while others recall layered mountain landscapes. Because each dial is cut from genuine natural azurite, no two dials are exactly alike.

Each azurite dial begins with a thin slice of natural stone that is carefully cut, shaped, polished and finished before being mounted onto a brass supporting base. This construction preserves the visual depth, texture and mineral character of genuine azurite while providing the structural stability needed for everyday wear.

Every Terra Gaia therefore carries its own natural pattern, color distribution and mineral formations.

Each dial is completely unique.

Powered by the Seiko Instruments / TMI VH31 sweeping-seconds quartz movement, Terra Gaia combines quartz accuracy and low-maintenance practicality with a smoother-running seconds hand.

With ±15 seconds per month accuracy, approximately 2 years of battery life, 100m / 10 ATM water resistance, a compact 38.5mm stainless-steel case, sapphire crystal with a 5-layer blue inner anti-reflective coating, and Super-LumiNova® BGW9 on the hands and hour indices, Terra Gaia brings natural depth and individuality into a watch designed for everyday wear.

## Natural Azurite Dial

The defining feature of Terra Gaia is its genuine natural azurite dial.

Dial Construction:
Natural Azurite Stone Slice on Brass Base

The visible surface is a thin slice of genuine natural azurite.

Each piece is carefully:
- Cut
- Shaped
- Polished
- Finished
- Mounted onto a brass supporting base

The brass base provides additional structural stability while allowing the natural stone itself to remain the visual focus of the watch.

## Every Dial Is Completely Unique

Natural azurite develops irregular mineral patterns, color variations and formations that cannot be reproduced exactly.

This means:

Every Terra Gaia dial is completely unique.

One dial may resemble flowing rivers.
Another may evoke the depth of the ocean.
Others may reveal layered formations that recall mountain landscapes or geological strata.

The watch shown in product photography represents the overall character of the material, but the exact dial received by the customer will have its own individual pattern.

This variation is not a defect.

It is an inherent characteristic of genuine natural stone and one of the defining features of Terra Gaia.

## TMI VH31 Sweeping-Seconds Quartz Movement

Terra Gaia is powered by:

Seiko Instruments / TMI VH31 Sweeping-Seconds Quartz

The VH31 is a fully quartz-regulated movement with a smoother-running seconds hand.

Unlike a conventional quartz watch where the seconds hand generally moves once per second, the VH31 advances the seconds hand in smaller, more frequent steps.

This creates a noticeably smoother visual motion while retaining the everyday convenience and accuracy of quartz.

Functions:
- Hours
- Minutes
- Sweeping Seconds
- No Date

Terra Gaia is:
Quartz

It is not:
- Automatic
- Mechanical
- Solar

## Movement Accuracy

Official VH31 accuracy:

±15 seconds per month

This is the preferred customer-facing specification.

Although this works out to roughly ±0.5 seconds per day on average, the official monthly figure should be used rather than presenting the converted daily figure as the main specification.

Approved wording:

Accuracy: ±15 seconds per month

## Battery

Battery Type:
SR920SW

Battery Voltage:
1.55V Silver Oxide

Approximate Battery Life:
2 Years

Actual battery life can vary depending on operating conditions.

Approved customer-facing wording:

Battery Life: Approximately 2 years

Do not guarantee exactly two years for every individual battery.

## Low-Maintenance Quartz Ownership

The VH31 is a low-maintenance quartz movement and does not require the same periodic mechanical servicing routine as a traditional mechanical movement.

Recommended routine maintenance includes:
- Battery replacement approximately every 2 years
- Inspection of the case gasket during battery replacement
- Inspection of sealing components
- Water-resistance testing after the case has been opened

Because Terra Gaia is rated to 100m / 10 ATM, checking water resistance after opening the case is particularly recommended.

If the movement develops a major fault, complete movement replacement may sometimes be more practical than carrying out a full movement overhaul.

## Operating Temperature

Specified VH31 operating temperature range:

Approximately -5°C to +50°C

Extreme temperatures or frequent large temperature changes may temporarily affect quartz timekeeping performance.

## Why We Call It “Sweeping-Seconds Quartz”

The VH31 is sometimes described in the market as a:

Meca-Quartz Movement

However, the more technically accurate description is:

Sweeping-Seconds Quartz Movement

The VH31 remains a fully quartz-regulated movement.

Its key visual characteristic is the smoother movement of the seconds hand.

For Terra Gaia, Shopify AI should preferably use:

TMI VH31 Sweeping-Seconds Quartz

instead of describing it primarily as meca-quartz.

## Sapphire Crystal with 5-Layer Inner AR Coating

Terra Gaia uses:

Sapphire Crystal with 5-Layer Blue Inner AR Coating

The anti-reflective coating is applied to the underside / inner surface of the sapphire crystal.

This helps provide:
- Strong everyday scratch resistance
- Better dial visibility
- Reduced distracting reflections
- A clearer view of the natural azurite surface

## Super-LumiNova® BGW9

Terra Gaia uses:

Super-LumiNova® BGW9 on the Hands and Hour Indices

Both the hands and hour markers use BGW9 luminous material.

This improves time readability in low-light conditions while maintaining a clean daytime appearance.

## Compact 38.5mm Case

Terra Gaia uses a compact and balanced case architecture.

Case Diameter:
38.5mm

Lug to Lug:
45.0mm

Thickness:
11.55mm

Dial Opening:
31.5mm

Lug Width:
20.0mm

These proportions give Terra Gaia a balanced wrist presence without feeling oversized.

The relatively compact 45.0mm lug-to-lug also helps keep the watch restrained across the wrist.

Actual fit will still depend on wrist shape and individual preference.

## 316L Stainless-Steel Case

## Why Choose Terra Gaia?

Terra Gaia is designed for customers who appreciate natural materials and want a watch with a genuinely individual appearance.

Its character comes from the contrast between:

Organic natural stone
and
precise modern watch construction.

The azurite dial brings:
- Natural variation
- Mineral depth
- Rich blue coloration
- Organic patterns
- Individual character

while the VH31 movement, sapphire crystal, 100m water resistance and stainless-steel construction provide everyday practicality.

Unlike a conventional colored dial where every watch is intended to look identical, the natural azurite surface means:

Every Terra Gaia develops its own visual identity.

## AI Customer Service Knowledge

Is the dial real azurite?

Yes.

Terra Gaia uses a genuine natural azurite stone slice mounted onto a brass base.

It is not a printed imitation stone pattern.

Is every dial unique?

Yes.

Every Terra Gaia dial is completely unique.

Natural azurite varies in mineral pattern, color distribution and formation, so no two dials will look exactly the same.

Will my watch look exactly like the photos?

Not exactly.

The product photographs represent the overall color and character of natural azurite, but the exact mineral pattern will vary from watch to watch.

The individual dial received by the customer will have its own unique appearance.

Is the variation a defect?

No.

Differences in pattern, mineral formations and color distribution are natural characteristics of genuine azurite.

They are part of what makes every Terra Gaia individual.

Why is the stone mounted on brass?

The azurite is cut into a thin natural stone slice and mounted onto a brass supporting base.

The brass provides structural stability while allowing the genuine stone surface to remain visible.

Is Terra Gaia automatic?

No.

Terra Gaia uses the TMI VH31 sweeping-seconds quartz movement.

It provides quartz accuracy and convenience while giving the seconds hand a smoother visual motion than a conventional one-tick-per-second quartz movement.

How accurate is it?

Official VH31 accuracy is:

±15 seconds per month

under normal operating conditions.

How long does the battery last?

Approximately:

2 years

The VH31 uses an:

It has relatively compact and balanced proportions for everyday wear.

Is Terra Gaia waterproof?

Do not say completely waterproof.

Approved answer:

Terra Gaia is rated to 100m / 10 ATM water resistance and uses a screw-down crown and screw-down case back.

How often does it need servicing?

The VH31 is a low-maintenance quartz movement.

Routine maintenance mainly consists of battery replacement approximately every two years.

When the case is opened for battery replacement, gasket inspection and water-resistance testing are recommended.

Can the bracelet be shortened?

Yes.

Bracelet links can be removed to shorten the bracelet.

The clasp also provides five micro-adjustment positions with approximately 10mm total adjustment.

Can the clasp be adjusted without tools?

No.

A small tool is required to reposition the spring bar between the five adjustment holes.

## Guidance for General Buyers

For customers who are less familiar with watches, explain the practical benefit before technical specifications.

Instead of saying only:

38.5mm case / 45mm lug-to-lug

say:

Terra Gaia uses a relatively compact 38.5mm case and a 45mm overall case length, giving it balanced proportions that are easier to wear than many larger sports watches.

Instead of only saying:

VH31 Sweeping Quartz

explain:

The VH31 gives you the convenience and accuracy of quartz, but its seconds hand moves more smoothly than a conventional quartz watch.

## Guidance for Gift Buyers

Terra Gaia can be particularly suitable as a gift because the natural azurite dial means every individual watch has its own pattern.

For gift buyers, prioritize:
1. Recipient's usual watch size
2. Wrist size if known
3. Whether they like blue watches
4. Whether they appreciate natural materials
5. Quartz versus mechanical preference
6. Whether low-maintenance ownership is important
7. Whether the individuality of a unique dial is meaningful to them

A useful gift explanation is:

Because every natural azurite dial is different, the watch received will have its own individual mineral pattern rather than being visually identical to every other Terra Gaia.
