Are you a detail-oriented watch enthusiast seeking a specific origin, or are you prioritizing pure functionality at an attractive price point? This comprehensive breakdown will equip you to choose the Seiko 5 SNXS79 that best suits your style and needs.
Unveiling the Seiko Story
Seiko needs no introduction to the watchmaking world. Founded in 1881, this Japanese powerhouse has consistently pushed boundaries with its technological advancements and dedication to quality. The Seiko 5 series, launched in 1968, embodies this spirit, offering a collection of automatic watches known for their durability, affordability, and timeless aesthetics.
The SNXS79, introduced in the late 2000s, quickly became a favorite among watch enthusiasts for its classic field watch design and exceptional value proposition.
A Technical Breakdown
While the SNXS79J1 and SNXS79K1 might appear identical at first glance, a closer look reveals a key distinction in their origin. Let’s delve into the technical aspects that make these watches tick.
Movement
Both the SNXS79J1 and SNXS79K1 utilize the tried-and-tested Seiko caliber 7S26 automatic movement. This workhorse movement boasts a reputation for reliability and longevity. Beating at a frequency of 21,600 vibrations per hour (3Hz), it offers smooth sweeping seconds of hand movement and a power reserve of approximately 40 hours after a full wind.
Here’s a table summarizing the key movement details:

|---|---|---|
| Movement | Seiko 7S26 Automatic | Seiko 7S26 Automatic |
| Movement Type | Automatic | Automatic |
| Frequency | 21,600 vph (3Hz) | 21,600 vph (3Hz) |
| Power Reserve | Approximately 40 hours | Approximately 40 hours |
Materials and Construction
Both variations utilize a stainless steel case (316L), offering a good balance of durability and corrosion resistance. The case size measures a modest 38mm in diameter and 12mm in thickness, making it a comfortable and versatile choice for most wrist sizes.
A hardlex crystal protects the dial, offering decent scratch resistance. Both models come equipped with a 20mm stainless steel bracelet, known for its comfortable and secure fit.

While both models share these core functions, a subtle aesthetic difference exists:
SNXS79J1: This model features the inscription “21 Jewels” on the dial at the 6 o’clock position. This indicates the number of jewels used in the movement, which can influence friction and wear resistance. While not a definitive guarantee of superior quality, some watch enthusiasts value this inscription as a potential indicator of a slightly higher level of quality control in the Japanese-made movement.
SNXS79K1: This model omits the “21 Jewels” inscription. This doesn’t necessarily signify a lower-quality movement, but some users might prefer the inscription for aesthetic reasons or perceived value.
Water Resistance
Both the SNXS79J1 and SNXS79K1 boast a water resistance rating of 30 meters (3 ATM). This makes them suitable for everyday activities like handwashing and light rain, but not ideal for swimming or diving.

Common Problems
Both the SNXS79J1 and SNXS79K1 are known for their durability and reliability. However,
Here are a few potential issues to keep in mind with both the SNXS72J1 and SNXS72K1:
Automatic movement: While offering the convenience of self-winding, automatic movements generally require servicing more frequently compared to quartz movements. Seiko recommends servicing your watch every 4-5 years, depending on usage and environmental conditions. Servicing costs can vary but can be a factor to consider compared to the lower maintenance of a quartz watch.
Limited water resistance: The 30-meter water resistance rating makes these watches unsuitable for swimming or diving. It’s best to keep them away from excessive water exposure.
Accuracy: While the 7S26 movement is generally reliable, it might not offer the same level of precision as a higher-end automatic or a quartz watch. Expect an accuracy range of +/- 15 seconds per day, which is acceptable for a watch at this price point.
The Final Lap
The decision ultimately boils down to your priorities:
The Detail-Oriented Enthusiast’s Choice: SNXS79J1
- If the potential for slightly higher quality control due to the “Made in Japan” origin and the “21 Jewels” inscription matters to you, then the SNXS79J1 might be your champion.
- You’re willing to pay a slight premium for the perceived benefits.
- You appreciate the classic field watch design and reliable performance.
The Budget-Conscious Watch Fanatic’s Choice: SNXS79K1
- If you prioritize affordability and ease of availability, the SNXS79K1 is the ideal choice.
- You’re comfortable with the Southeast Asian production origin.
- The lack of the “21 Jewels” inscription doesn’t hold significant weight for you.
Consider these additional factors:
- Aesthetics: Do you prefer the dial with or without the “21 Jewels” inscription?
- Availability: Check with authorized retailers in your area to see which model is more readily available.
- Budget: While the price difference might be minimal, factor in the potential servicing costs of an automatic movement compared to a quartz watch.
Ultimately, the best way to choose your champion is to try on both watches if possible. Feel the weight on your wrist, assess their legibility, and consider which one resonates more with your style and priorities. Remember, the perfect Seiko SNXS79 is the one that brings you joy and serves you reliably for years to come.
