Kamasu boasts a superior sapphire crystal and in-house movement with hacking and hand-winding, while Seiko 5 counters with a wider range of dials, a legendary brand name, and a slightly larger case size. For value and functionality, Kamasu wins. For brand recognition and style options, Seiko takes the crown.
Introduction
You’re in the market for a stylish, reliable dive watch that won’t break the bank. Two names constantly pop up in your research: the Orient Kamasu and the Seiko 5 Sports (also known as the 5KX).
Both are phenomenal options, boasting automatic movements, impressive water resistance, and a bold aesthetic. But with so many similarities, choosing between them can feel like navigating a minefield.
Fear not, watch enthusiast! This comprehensive guide will break down the key differences between the Orient Kamasu and Seiko 5, equipping you to make the perfect choice for your wrist.
A Look at Seiko and Orient’s History
Seiko: Founded in 1881, Seiko is a legendary Japanese watchmaker synonymous with innovation and quality. From the world’s first quartz wristwatch to the iconic Seiko divers, the brand has consistently pushed the boundaries of horology.
The Seiko 5, launched in 1968, embodied this spirit, offering automatic movements, durability, and affordability to a wider audience.
Orient: Established in 1901, Orient is another Japanese powerhouse with a rich heritage. While perhaps not as globally recognized as Seiko, Orient is revered for its in-house movements, exceptional craftsmanship, and commitment to offering automatic watches at accessible price points.
The Orient Kamasu, released in 2017, embodies this philosophy, providing a feature-packed, stylish diver at a competitive price.
Technical Breakdown
Now, let’s get down to the nitty-gritty and compare the technical specifications of these two compelling timepieces.
Movement
Orient Kamasu: The Kamasu features the Orient F6922, a 21-jewel automatic movement boasting a 50-hour power reserve, hacking seconds (ability to stop the second hand for precise time setting), and hand-winding functionality.
Seiko 5 Sports: The Seiko 5 utilizes the tried-and-true 4R36 automatic movement, known for its reliability and ease of maintenance. It offers a 41-hour power reserve and lacks hacking seconds and hand-winding capabilities.
Winner: This round depends on your priorities. If hacking and hand-winding are crucial, the Kamasu wins. For pure reliability and long service history, the Seiko 5 takes the crown.
Materials and Construction
Orient Kamasu: The Kamasu boasts a 316L stainless steel case with a polished finish, a sapphire crystal for excellent scratch resistance, and a screw-down crown for enhanced water resistance. The bracelet is also stainless steel with a solid fold-over clasp and a diver’s extension.
Seiko 5 Sports: The Seiko 5 also features a 316L stainless steel case but with a mix of polished and brushed finishes. It utilizes Hardlex crystal, which is quite durable but more susceptible to scratches compared to sapphire. The bracelet is stainless steel with a similar clasp and extension.
Winner: The Kamasu edges out the Seiko 5 here. Sapphire crystal offers superior scratch resistance, a crucial feature for a dive watch.
Functions and Features
Both watches offer essential timekeeping functions – hours, minutes, seconds, and a date complication. However, the Kamasu provides a slight edge:
Orient Kamasu: Luminous hands and indices for low-light visibility. Uni-directional rotating bezel for tracking elapsed dive time.
Seiko 5 Sports: Luminous hands and indices. Uni-directional rotating bezel for dive time tracking. Day and date complication at the 3 o’clock position (some variations offer only date).
Winner: While the Seiko 5 offers a day-date complication (a convenient feature for everyday wear), the Kamasu’s superior lume ensures better readability in low-light conditions, a crucial factor for a dive watch. However, if the day-date function is a dealbreaker for you, the Seiko 5 remains a compelling option.
Water Resistance
Both the Orient Kamasu and Seiko 5 boast an impressive 200-meter (20 ATM) water resistance rating. This makes them suitable for recreational diving, swimming, and snorkeling.
Winner: It’s a tie! Both watches excel in aquatic environments.
Power Source
Both watches are automatic, meaning they derive their power from the natural motion of your wrist. However, they also offer manual winding capabilities (Kamasu) or a hidden crown for hand-winding (some Seiko 5 variations). Both offer the option to wind the watch manually for a power reserve boost if not worn regularly.
Winner: It’s a tie! Both offer convenient ways to keep your watch running.
Design and Aesthetics
Now, we move beyond technical specifications and delve into the realm of aesthetics. Here, the choice truly boils down to your personal taste.
Dial Design
Orient Kamasu: The Kamasu offers a classic, clean dive watch aesthetic. The applied indices and well-proportioned hands provide excellent legibility. The dial comes in a variety of colors, including blue, black, green, and sunray blue, catering to diverse preferences.
Seiko 5 Sports: The Seiko 5 boasts a wider variety of dial colors and finishes, including playful sunray patterns, textured dials, and even skeletonized options. The markers and hands offer good legibility, but some variations might appear busier than the Kamasu’s dial.
Winner: This is subjective. The Kamasu offers a timeless design, while the Seiko 5 caters to those who prefer a more playful or unique aesthetic.
Case and Bezel
Orient Kamasu: The Kamasu features a well-proportioned 41.5mm case with a polished finish and a comfortable lug-to-lug length. The uni-directional bezel has a smooth, 120-click operation and clear markings.
Seiko 5 Sports: The Seiko 5 has a slightly larger 42.5mm case with a mix of polished and brushed finishes. The uni-directional bezel also offers a 120-click operation, but some users report a slightly less refined feel compared to the Kamasu.
Winner: This is a close call. The Kamasu offers a slightly more refined case and bezel, but the Seiko 5 might be a better fit for those with larger wrists.
Clasp & Bracelet
Orient Kamasu: The Kamasu comes with a solid, three-fold clasp with a diver’s extension for wearing over a wetsuit. The bracelet is comfortable and well-made.
Seiko 5 Sports: The Seiko 5 also features a three-fold clasp with a diver’s extension and a comfortable bracelet. However, some users report the clasp feeling slightly less secure compared to the Kamasu.
Winner: The Kamasu takes a slight lead here with its more robust clasp.
Brand Image
Orient: A respected brand among watch enthusiasts, known for its exceptional value proposition and in-house movements. However, it might not have the global recognition of Seiko.
Seiko: A legendary watchmaker with a strong brand reputation for innovation and quality.
Winner: Seiko enjoys wider brand recognition, but Orient offers a compelling alternative for those seeking exceptional value.
