Terra Pearl

# Terra Pearl

## Product Overview

Terra Pearl captures the quiet beauty of natural abalone shell, with a soft iridescent glow that shifts gently as light moves across the dial.

Each dial is carefully cut, joined, polished, and finished to reveal the natural texture and color variation of the shell. Because abalone is a natural material, every dial develops its own individual pattern, iridescence, and tonal character.

No two Terra Pearl dials are exactly alike.

Available in two distinctive colorways:

- Verdant
- Amethyst

Verdant emphasizes cooler green and blue tones with a fresh, organic character.

Amethyst leans toward richer violet, purple, and iridescent tones, giving the dial a more expressive and jewel-like appearance.

Powered by the Seiko Instruments / TMI VH31 sweeping-seconds quartz movement, Terra Pearl 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, and the same bracelet architecture as Terra Gaia, Terra Pearl brings natural elegance and shifting color into a watch designed for everyday wear.

## Natural Abalone Shell Dial

The defining feature of Terra Pearl is its genuine natural abalone shell dial.

Each dial is carefully:

- Cut
- Joined
- Polished
- Finished

The natural shell surface creates subtle changes in color and brightness depending on the viewing angle and surrounding light.

Unlike a conventional painted dial, the visual character comes from the shell itself.

## Every Dial Is Unique

Natural abalone shell varies naturally in:

- Color distribution
- Iridescent intensity
- Surface texture
- Pattern
- Tonal transitions

As a result:

Every Terra Pearl dial is unique.

The product photographs represent the overall color direction of each version, but the exact pattern and iridescence of the watch received by the customer will vary.

This variation is not a defect.

It is an inherent characteristic of genuine natural abalone shell.

## Colorways

### Terra Pearl Verdant

Verdant emphasizes green, blue-green, and cool iridescent tones.

Depending on the light and viewing angle, the dial may reveal different combinations of green, blue, turquoise, and subtle pearlescent highlights.

Its overall character is fresh, organic, and understated.

### Terra Pearl Amethyst

Amethyst emphasizes violet, purple, and richer iridescent tones.

As the light moves across the dial, the shell may reveal shifting purple, blue, pink, and pearlescent highlights.

Its overall character is more expressive, elegant, and jewel-like.

Important:

Because natural shell varies from piece to piece, the exact balance of colors will not be identical on every dial.

## TMI VH31 Sweeping-Seconds Quartz Movement

Terra Pearl 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 typically advances once per second, the VH31 moves the seconds hand in smaller, more frequent steps.

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

## Battery

Battery Type:
SR920SW

Battery Voltage:
1.55V Silver Oxide

Approximate Battery Life:

Actual battery life may vary depending on operating conditions.

## Low-Maintenance Quartz Ownership

The VH31 is a low-maintenance quartz movement and does not require the same periodic servicing routine as a 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 Pearl is rated to 100m / 10 ATM, water-resistance testing after opening the case is recommended.

## Why Choose Terra Pearl?

Terra Pearl is designed for customers who appreciate natural materials but prefer a softer, more luminous visual character than a traditional stone dial.

Its personality comes from the contrast between:

Natural iridescent shell
and
precise modern watch construction.

The abalone dial brings:
- Natural iridescence
- Shifting color
- Organic texture
- Individual pattern variation
- A softer, more elegant visual character

while the VH31 movement, 100m water resistance, stainless-steel construction, and practical bracelet architecture provide everyday usability.
