Discover the Seiko SNK375: The Perfect Affordable Automatic Watch for Everyday Wear

Introduction

If you're on the hunt for a compact, reasonably-priced automatic sports watch that bridges the gap between high-end automatics and robust G-SHOCK digital timepieces, you're in the right place. Many new watch collectors and enthusiasts often realise a void in their collection: the need for a "beater" watch, a reliable piece for everyday wear where a more expensive model may not be suitable. Normally in such circumstances, I would recommend the aforementioned G-SHOCK range but what if you want a more traditional analog watch? Let me introduce you to the solution: The Seiko 5 series, specifically the Seiko SNK375K1.

The Legendary Seiko 5 Series

Seiko 5 watches have a staggering history and heritage, lasting several decades. The principles of the Seiko 5 range are surprisingly built on five key aspects:

  • Water resistance

  • Seiko’s Diaflex technology (unbreakable mainspring)

  • Automatic winding

  • Day-Date complication

  • Diashock (Seiko’s shock-resistant design)

Out of the vast selection, the model I personally settled on is the Seiko SNK375K1, also known as the Racing Dial.

The Seiko SNK375K1: A Closer Look

The Case and Design

The 36mm case is on the smaller side, making it comfortable and well-fitting for everyday wear. It slips under the cuff smoothly, and the blend of finely brushed and polished finishes gives it a versatile aesthetic. This also makes this a very accessible piece for most wrist sizes! The lug width is 18mm, which means strap options are slightly more limited. However, I settled on a superb rubber strap with contrasting red stitching that suits the dial perfectly! Although it lacks a screw-down crown, the SNK375 still provides 30 meters of water resistance - not suitable for diving but sufficient for everyday exposure to water. In my time spent with the little Seiko, I haven’t had any issues with the water resistance.

The Movement

The Seiko 7S26 movement powers the watch inside the stainless steel case, featuring a day/date complication. With a solid 41-hour power reserve, it's reliable, albeit lacking hand winding or hacking features. Although the movement's accuracy might not win competitions (-20 to +49 seconds a day), it's a dependable and sturdy movement used across the Seiko range.

The Dial

What attracted me most to the SNK375K1 was the dial. The deep black background is adorned with an applied Seiko and 5 logos at the 12 o'clock position, applied lume-filled baton indices, and a minute track, all of which provide excellent visibility. The contrasting red second hand and the red and grey section for the first 20 minutes give the watch a unique and appealing aesthetic that really catches the eye with the right strap pairing!

Room for Improvement

As with all watches, there are areas where the SNK375 could improve. The bracelet, for example, lacks character and does not suit the overall character of the watch. I replaced it with the rubber strap with red stitching and this is available here, which enhances the aesthetic. Another point of contention is the Hardlex crystal, which, if scratched, would require replacement, making an acrylic crystal a preferable choice in my view and especially at this price point. 

Conclusion

With the SNK375K1, Seiko delivers yet another sharp, sporty design that's perfect for daily wear. This easy, everyday wearable automatic watch, steeped in Seiko heritage, comes at a sensible price, and with minor drawbacks that are quite acceptable at this price point. The Seiko 5 range has consistently delivered reliable, affordable watches with a broad appeal. For me, the SNK375K1 is a clear winner in the realm of everyday automatic watches.

Frequently Asked Questions about Seiko 5 Watches

Q: What does "Seiko 5" mean?

A: The "5" in Seiko 5 refers to the five key features that Seiko aimed to include in every watch of this series: automatic winding, day/date displayed in a single window, water resistance, a recessed crown at the 4 o’clock position, and a durable case and bracelet.

Q: Are Seiko 5 watches automatic?

A: Yes, one of the core principles of Seiko 5 watches is that they are automatic. This means they are self-winding and powered by the natural motion of the wearer's wrist.

Q: How accurate are Seiko 5 watches?

A: The accuracy of Seiko 5 watches can vary, but many models like the SNK375K1 have a daily variance of -20 to +49 seconds. While this isn't top-tier accuracy, it is quite reasonable for an affordable automatic watch.

Q: Can you manually wind a Seiko 5 watch?
