145 Years of Seiko: A Legacy of Japanese Watchmaking

Seiko's story began in 1881, when Kintaro Hattori opened a watch and jewelry shop in Tokyo's Ginza district. His ambition to create reliable, innovative timepieces laid the foundation for a company that would become one of the most influential names in the global watch industry.

Over the decades, Seiko introduced important milestones in watchmaking, including Japan's first wristwatch in 1913 and the Quartz Astron in 1969, the world's first quartz wristwatch. These achievements reflect the brand's longstanding commitment to precision, innovation and accessible watchmaking.

The 145th Anniversary Limited Edition collection celebrates this history through designs inspired by Japanese culture and Seiko's identity. The HGH004 stands out with its purple dial, a color associated with the historic aesthetic of Edo, the former name of Tokyo.

Rather than relying on an elaborate design, this model expresses the anniversary theme through a distinctive dial color and elegant proportions. It is a subtle tribute to Seiko's Japanese heritage.

The Edo Purple Dial: A Distinctive Japanese Inspiration

The most recognizable feature of the Seiko HGH004 is its rich purple dial. Inspired by Edo Purple, the color connects the watch to the cultural history of Tokyo and gives the anniversary model a distinctive visual identity.

The dial features a textured appearance that adds depth as light moves across its surface. Its purple tone creates an elegant contrast with the polished stainless steel case and bracelet, making the watch visually interesting without sacrificing its classic character.

Roman Numeral Hour Markers

Roman numeral hour markers bring a traditional touch to the dial. Their clear layout complements the watch's refined proportions and reinforces its timeless aesthetic.

Gold-Tone Hands and Central Details

Gold-tone hands add warmth to the purple dial, creating a subtle contrast against the darker background. The combination of purple, gold and silver gives the HGH004 a sophisticated appearance that works across different styles.

A Balanced and Legible Design

The dial keeps its layout clean and easy to read. Rather than adding unnecessary complications, Seiko focuses on the essentials: hours, minutes and a central seconds hand.

The purple dial is the defining detail of the HGH004 anniversary edition.

29.6mm Stainless Steel Case: Elegant and Comfortable Proportions

The Seiko HGH004 features a 29.6mm stainless steel case with a slim profile of just 6.2mm. These proportions create a refined silhouette that sits comfortably on the wrist and makes the watch suitable for a wide range of occasions.

Its 36.9mm lug-to-lug measurement contributes to the overall balance of the design. The polished stainless steel finish complements the purple dial and gives the watch a clean, versatile appearance.

A Slim Profile for Everyday Wear

At 6.2mm thick, the case has a streamlined profile that can slide easily beneath a shirt cuff or the sleeve of a tailored jacket. Its compact dimensions make it a practical option for those who prefer a watch that feels elegant rather than oversized.

Stainless Steel Bracelet

The matching stainless steel bracelet completes the design. Its metallic finish creates a cohesive look with the case, while the three-fold clasp with push-button release provides a secure closure.

Seiko Caliber 6N01 Quartz Movement: Reliable Japanese Precision

The Seiko HGH004 is powered by the Seiko Caliber 6N01 quartz movement. This movement is designed to provide dependable timekeeping with minimal daily maintenance.

Quartz technology uses an electronic oscillator regulated by a quartz crystal to maintain consistent timekeeping. It is valued for its accuracy, practicality and ease of use, making it a popular choice for watches intended for everyday wear.

Accuracy of Approximately ±15 Seconds per Month

The Caliber 6N01 offers an approximate accuracy of ±15 seconds per month. This level of precision makes the watch a practical option for people who want reliable timekeeping without the regular winding associated with mechanical watches.

Approximately Three Years of Battery Life

The movement offers an estimated battery life of approximately three years. Actual battery life may vary depending on operating conditions and usage.

Why choose quartz? The Seiko 6N01 offers straightforward operation, dependable accuracy and low-maintenance ownership. It is a practical alternative to mechanical movements for everyday use.

Sapphire Crystal and Everyday Durability

The Seiko HGH004 features a sapphire crystal that protects the dial. Sapphire is valued in watchmaking for its excellent scratch resistance, helping the watch maintain a clear appearance through regular use.

The stainless steel case and bracelet provide a durable exterior, while the 50-meter water-resistance rating adds practicality for everyday situations.

What Does 50-Meter Water Resistance Mean?

The 5-bar rating indicates that the watch is designed to withstand everyday exposure to water under the conditions specified by the manufacturer. It is not a diving watch, and water resistance should not be interpreted as an invitation to expose the watch to hot water, steam or high-pressure water.

As with any watch, it is important to keep the crown properly positioned and follow Seiko's care recommendations to help preserve its water resistance over time.

Seiko HGH004 vs. Traditional Mechanical Watches

The Seiko HGH004 uses a quartz movement rather than a mechanical automatic movement. Both technologies have their own advantages, and the right choice depends on personal preferences.

Feature Seiko HGH004 Quartz Mechanical Automatic Watch
Power Source Battery Mainspring
Timekeeping Quartz-regulated electronic movement Mechanical regulating system
Accuracy Approximately ±15 seconds per month Varies by movement and conditions
Maintenance Periodic battery replacement Periodic mechanical servicing
Daily Operation Convenient and low-maintenance May require winding or regular wear

For someone who values convenience and consistent everyday accuracy, the HGH004 is a practical choice. Collectors who enjoy traditional mechanical engineering may prefer an automatic watch. Neither technology is universally better; they simply offer different ownership experiences.

How to Care for Your Seiko HGH004

Regular care helps preserve the appearance and performance of your Seiko anniversary watch. A few simple habits can help protect its case, bracelet and movement.

  • Clean the case and bracelet: Use a soft microfiber cloth to remove fingerprints and surface dust.
  • Avoid scratches: Keep the watch away from hard surfaces and avoid storing it loose with other jewelry.
  • Protect the movement: Avoid strong impacts and unnecessary exposure to extreme temperatures.
  • Respect water resistance: Keep the watch away from hot water, steam and high-pressure water.
