How Are Dive Watches Made? Inside the LONGVISION Voyage Collection

A dive watch is more than a timepiece with a water-resistant case. It is a combination of mechanical engineering, carefully selected materials, precision components, and functional design.

Every detail matters — from the movement that powers the watch to the crystal protecting the dial, the ceramic bezel surrounding it, and the luminous markers that help improve visibility in low-light conditions.

At LONGVISION, we believe that a well-designed dive watch should bring together reliable mechanical performance, practical functionality, and distinctive style.

In this article, we take a closer look at how the LONGVISION Voyage Collection is designed, what goes into its construction, and how its key components contribute to the experience of wearing an automatic dive watch.

1. Starting with the Movement: The Heart of an Automatic Dive Watch

The movement is the heart of every mechanical watch. It determines how the watch keeps time and reflects much of the engineering behind the timepiece.

Selected LONGVISION Voyage models are equipped with the Swiss Sellita SW200-1 automatic mechanical movement.

Unlike a quartz watch that relies on a battery, an automatic mechanical movement uses the motion of the wearer's wrist to wind its mainspring. Energy is stored in the mainspring and gradually released through the movement's gear train and regulating system to keep the hands moving.

Why choose the Sellita SW200-1?

• Swiss automatic mechanical movement

• Self-winding operation

• Mechanical construction without a conventional watch battery

• A well-established movement used in mechanical watchmaking

For watch enthusiasts who appreciate traditional mechanical engineering, the movement is an important part of the overall experience.

It is worth noting that LONGVISION watches are manufactured in mainland China. Selected models use Swiss movements, including the Sellita SW200-1. A Swiss movement does not mean the entire watch is Swiss Made.

2. Building a Durable Case for 300M Water Resistance

Water resistance is one of the defining features of a dive watch.

The LONGVISION Voyage Collection features a rated water resistance of 300 meters (1,000 feet), designed for users who value a robust watch with substantial water-resistance specifications.

Achieving a 300M water-resistance rating requires more than simply using a thick case. The watch's construction must be designed to help prevent water from entering through vulnerable areas.

Important elements include:

• A carefully constructed watch case

• Sealing around the case back

• Sealing around the crown

• A properly fitted crystal

• A secure case and component assembly

These elements work together to help protect the movement from water intrusion.

A 300M rating is a technical specification, not a recommendation to operate the crown or pushers underwater. Always follow the watch's operating instructions and make sure the crown is properly secured before water exposure.

3. High-Fired Ceramic Bezel: Designed for Durability and Style

The bezel is one of the most recognizable features of a dive watch. It contributes to the watch's appearance while providing a practical timing reference.

The LONGVISION Voyage Collection features a high-fired ceramic bezel.

Why use ceramic?

Ceramic is valued in watchmaking for its hardness, surface stability, and resistance to everyday scratches. It also maintains a refined appearance and provides a distinctive finish around the dial.

Key characteristics include:

• High hardness

• Good resistance to everyday surface scratches

• A refined, glossy appearance

• A durable finish designed for long-term use

The ceramic bezel is not simply a decorative detail. It is part of the overall design language of the Voyage Collection, combining practical material selection with a distinctive visual identity.

4. Sapphire Crystal: Protecting the Dial with Clarity

The crystal is the transparent component that protects the watch dial.

For an everyday watch, it needs to provide clear visibility while helping protect the dial from scratches and accidental contact.

LONGVISION Voyage models use sapphire crystal, a material widely appreciated in watchmaking for its excellent scratch resistance.

Selected models also feature an integrated flat sapphire magnifier above the date window at 3 o'clock.

This detail makes the date easier to read while maintaining a clean, integrated appearance.

The combination of sapphire crystal and the date magnifier gives the dial a practical feature without distracting from its overall design.

5. Swiss Super-LumiNova: Visibility in Low-Light Conditions

A dive watch should remain readable when lighting conditions become challenging.

The LONGVISION Voyage Collection uses Swiss Super-LumiNova luminous material on selected dial elements, including the hands and hour markers.

After exposure to light, luminous material stores energy and gradually releases it as visible light in darker environments.

This helps the wearer read the time when ambient light is limited.

Why does lume matter on a dive watch?

• It improves time readability in low-light conditions.

• It makes the hands and hour markers easier to distinguish.

• It adds practical functionality to the dial.

• It supports the traditional visual language of dive watches.

For LONGVISION, luminous details are not just decoration. They are an important part of making the watch easier to read in different lighting environments.

6. 316L Stainless Steel Bracelet: Comfort and Everyday Wear

A dive watch needs to feel as practical on the wrist as it looks.

The LONGVISION Voyage Collection uses 316L stainless steel bracelets, a material commonly used in quality watchmaking.

316L stainless steel is valued for its corrosion resistance, durability, and suitability for everyday wear.

The bracelet combines brushed and polished finishing to create visual contrast and give the watch a more refined appearance.

Its design allows the Voyage Collection to work in different settings — from casual everyday outfits to more polished occasions.

7. Balancing Function and Design: The LONGVISION Voyage Collection

A good dive watch should not be limited to technical specifications. Its proportions, dial design, materials, and overall finishing also influence how it feels and looks on the wrist.

The LONGVISION Voyage Collection brings together several important dive-watch features:

• 300M / 1,000ft rated water resistance

• Sapphire crystal

• High-fired ceramic bezel

• Swiss Super-LumiNova luminous material

• 316L stainless steel bracelet

• Selected models with Swiss Sellita SW200-1 automatic movements

• Selected models with an integrated sapphire date magnifier

The collection also offers different dial colors and case sizes, including 37mm and 41mm options on selected models.

This gives watch enthusiasts more flexibility when choosing a watch that suits their wrist size and personal style.

Whether you prefer a classic black dial, a blue dial, or a more distinctive color combination, the Voyage Collection brings functional dive-watch elements together with a modern mechanical-watch aesthetic.

8. What Makes the LONGVISION Voyage Collection Different?

At LONGVISION, our watchmaking background dates back to 2009. Our experience in watch manufacturing has shaped the way we approach product development, component selection, and design.

Rather than focusing on appearance alone, we pay attention to the details that define the wearing experience:

• Mechanical movement selection

• Water-resistance specifications

• Crystal material and dial readability

• Ceramic bezel construction

• Luminous performance

• Bracelet materials and finishing

The goal is to create watches that combine practical specifications with thoughtful design.

The Voyage Collection reflects this approach: a mechanical dive-watch collection designed for people who appreciate both the engineering behind a watch and the details they can see and feel every day.
