Terra Nova

# Terra Nova

## Product Overview

Terra Nova explores the individuality of natural stone through four distinctive dial materials:

1. Terra Nova Rose Quartz
2. Terra Nova Black Agate
3. Terra Nova Rhodochrosite
4. Terra Nova Amazonite

Each variation expresses a different side of natural stone, from the soft warmth of rose quartz and the deep, understated character of black agate, to the layered mineral tones of rhodochrosite and the fresh blue-green character of amazonite.

Each dial is made from a thin slice of genuine natural stone that is carefully cut, shaped, polished and finished before being mounted onto a brass supporting base.

Because natural stone forms through irregular mineral processes, no two pieces develop exactly the same color distribution, veining or mineral pattern.

Every Terra Nova dial is completely unique.

Terra Nova uses the same case, bracelet and movement architecture as Terra Gaia, combining natural-stone individuality with compact everyday proportions and low-maintenance quartz performance.

Powered by the Seiko Instruments / TMI VH31 sweeping-seconds quartz movement, Terra Nova offers ±15 seconds per month accuracy, approximately 2 years of battery life, and a smoother-running seconds hand than a conventional one-tick-per-second quartz movement.

A compact 38.5mm 316L stainless-steel case, sapphire crystal with 5-layer blue inner AR coating, Super-LumiNova® BGW9 on the hands and hour indices, and 100m / 10 ATM water resistance make Terra Nova practical enough for everyday wear while allowing the natural stone dial to remain the visual centerpiece.

## Four Natural-Stone Variations

### Terra Nova Rose Quartz

Terra Nova Rose Quartz captures the gentle beauty of natural rose quartz, with soft pink tones and subtle mineral patterns that shift quietly across the dial.

Each dial is carefully cut, shaped, polished and finished to reveal the natural texture of the stone.

Some pieces may appear softer and more uniform, while others may reveal subtle cloudy structures, tonal variations or naturally occurring mineral patterns.

Because every dial is made from genuine natural rose quartz:

No two Terra Nova Rose Quartz dials are exactly alike.

The result is a warm, refined and understated expression of the Terra Nova collection.

### Terra Nova Black Agate

Terra Nova Black Agate takes a darker and more restrained approach to natural stone.

Its deep black surface creates a clean and sophisticated appearance, while subtle natural mineral variations prevent the dial from feeling completely flat or artificial.

Depending on the individual stone and lighting, the dial may reveal slight tonal changes and natural structures beneath its dark surface.

Each dial is cut and finished from genuine natural black agate.

Therefore:

Every Terra Nova Black Agate dial has its own individual natural character.

Its darker appearance makes it one of the most understated and versatile expressions within the Terra Nova collection.

### Terra Nova Rhodochrosite

Terra Nova Rhodochrosite highlights one of the more expressive natural-stone personalities in the collection.

Its surface can reveal pink, rose and lighter mineral bands arranged in naturally formed patterns.

These layered structures can vary considerably from stone to stone, giving each dial a distinctive appearance.

Some pieces may show stronger banding, while others may feature softer transitions between different shades.

Because these patterns are formed naturally:

Every Terra Nova Rhodochrosite dial is completely unique.

The result combines natural warmth with a more visually expressive mineral structure.

### Terra Nova Amazonite

Terra Nova Amazonite brings a fresher blue-green expression to the collection.

Natural amazonite can display variations between green, turquoise and blue-green tones, together with lighter mineral structures that move across the surface.

These natural color variations give each dial its own character.

Some pieces may lean more toward green, while others may reveal cooler blue or turquoise tones.

Because every dial is cut from genuine natural amazonite:

No two Terra Nova Amazonite dials are exactly alike.

Its fresh color palette gives Terra Nova Amazonite a distinctive personality while retaining the natural depth and individuality shared across the Terra Nova collection.

## Natural Stone Dial Construction

All four Terra Nova variations use the same fundamental dial construction:

Natural Stone Slice on Brass Base

Depending on the SKU, the visible stone surface is:

- Rose Quartz
- Black Agate
- Rhodochrosite
- Amazonite

Each stone slice is carefully:

- Cut
- Shaped
- Polished
- Finished
- Mounted onto a brass supporting base

The brass base provides structural stability while allowing the genuine natural stone surface to remain the visual focus.

## Every Dial Is Unique

Natural stone does not form according to a standardized printed pattern.

Differences can appear in:

- Color distribution
- Veining
- Mineral bands
- Clouding
- Natural inclusions
- Pattern density

As a result:

Every Terra Nova dial is completely unique.

Product photography represents the overall character of each stone type, but the exact dial received by the customer will vary naturally.

These differences are not defects.

They are part of the natural material and one of the defining characteristics of the Terra Nova collection.

## TMI VH31 Sweeping-Seconds Quartz Movement

All Terra Nova models use the same movement as Terra Gaia:

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

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

Functions:

- Hours
- Minutes
- Sweeping Seconds
- No Date

- Automatic
- Mechanical
- Solar

## Low-Maintenance Quartz Ownership

The VH31 is a low-maintenance quartz 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 Nova is rated to 100m / 10 ATM, water-resistance testing is recommended after battery replacement or whenever the case has been opened.

## Sapphire Crystal

Terra Nova uses the same crystal specification as Terra Gaia:

Sapphire Crystal with 5-Layer Blue Inner AR Coating

The anti-reflective coating is located on the inner / underside surface of the sapphire crystal.

This provides:

- Strong everyday scratch resistance
- Reduced reflections
- Better dial visibility
- A clearer view of the natural stone texture

## Super-LumiNova® BGW9

Terra Nova uses:

Super-LumiNova® BGW9 on the Hands and Hour Indices

Both the hands and hour markers feature BGW9 luminous material for improved low-light legibility.
