Seiko 5 Sports SRPD75 Green Bezel & Dial Watch

I’ve been fortunate enough to have the chance to wear & review a wide array of Seiko 5 Sports models. On numerous occasions, with over a dozen watches at my disposal, I found myself constantly reaching for this SRPD75.

From the green sunray dial that I think is a uniquely attractive tone to the Milanese bracelet that is not only elegant but also surprisingly comfortable and everything else in between. There are countless aspects of this SRPD75 that make it a must-have and I’ll be going through all of them in this review via the following sections:

  2. Case & Bezel
  3. Dial
  4. Bracelet
  5. Movement
  6. Overall Thoughts

The watch used in this review is a Made in Japan model so it is advertised under the reference SBSA019. Except for some minimal differences, the SBSA019 is virtually the same as non-Made in Japan versions that are sold under the reference SRPD75.

The Seiko SRPD75’s Case

If you’re familiar with the Seiko SKX case profile, then you are already familiar with the SRPD75. That’s because the case design is exactly the same, though I do believe it wears differently due to the bracelet. I’ll be delving deeper into this bracelet later in the review, so let’s continue on with the case dimensions; they are:

  • 42.5mm case diameter (9 to 3 o’clock)
  • 13.4mm max thickness
  • 46mm lug-to-lug
  • 22mm between lugs (22mm strap size)

The case is by no means a small one, especially when it comes to thickness. This is clearly a sportier watch and it doesn’t try to hide this aspect one bit. However, the proportions make it so that the watch wears quite comfortably – it is not bulky or oversized even on smaller wrists such as mine.


Personally, I tend to prefer timepieces closer to 40mm in diameter. And yet, I did not feel as if I was wearing a much larger timepiece when sporting this SRPD75.

As far as surface finishes, the SRPD75 has the typical 5 Sports satin/brushed finish on the top of the case and high-polish case flanks. These two contrasting finishes meet at a slim bezel towards the top of the case that adds a nice bit of complexity to the overall case design.

Green Bezel

SRPD75-Green-Dial-Green-Bezel-Hulk-Seiko-WatchThe bezel on the SRPD75 is a typical unidirectional diver’s bezel with 120 clicks. It has a textured outer surface that makes it easier to rotate, particularly when the watch (or your hands) are wet. Neatly nestled inside the bezel is a metallic green insert with a diver’s scale in silver font.

Regarding the bezel color – it’s possible some would refer to this green tone with another name. I’ve personally called it olive or military green in the past, though for simplicity’s sake, I’m sticking with green for the rest of this review. Perhaps you can get your hands on an SRPD75, experience it in the flesh, and then let me know in the comments what tone of green is most appropriate.

5 Sports SRPD75 Dial Details

The dial of the SRPD75 is probably one of my favorite characteristics of the watch. It is a deep green color with a sunray finish that explodes in the sunlight. I’ve tried to capture this effect in the attached pictures but they hardly do this watch justice.


Also present on the dial are applied hour indices with beige-colored patina. Each index, as well as the brushed-finish hands at center, are fully lumed with LumiBrite. It’s worth noting that this lume is blue as opposed to the green lume encountered on most other Seiko 5 Sports models.

Seiko-5-Sports-Green-Dial-And-Bezel-WatchSurrounding the entire dial of the SRPD75 is a cream-colored minute track (or rehaut) that is imprinted with black minute markings. I’m a fan of this style of minute track; I think it gives the dial depth while also blending adequately with both the green of the bezel/dial and the “patina” lume of the hands/indices.

At 3 o’clock we find the last key element of this watch: the complication display. Of course, in this case, it is a rectangular opening that displays the day and date wheels which are composed of black text on a stark white background.

Steel Milanese (Mesh) Strap

Second only to the dial, the steel Milanese bracelet is a highlight of this watch. What I initially misconstrued as a bulky and unnecessary bracelet choice has now become my favorite band type within the Seiko 5 Sports collection, namely due to this SRPD75

The mesh of the bracelet reflects light in countless directions. This inevitably draws eyes towards the wrist, much like jewelry does. In my opinion, this characteristic makes the watch much more elegant than if it were presented on a different strap or bracelet.

The advantages of the Milanese bracelet extend past just the aesthetics, though. The bracelet is truly comfortable. I’ve had no issues with hair-pulling as I first expected, and there’s plenty of hair on my wrist to grab on to. The bracelet is also not as heavy as I thought before I wore it, and either way its heft does a proper job of balancing with the watch head.


The clasp is quite secure and, while it can be difficult to adjust to the proper length to fit your wrist, once it is set you will never have to worry about it again. I chose to leave a bit of extra space as I know my wrist swells and deflates throughout the day, yet it remains comfortable at either stage.

I also think it’s worthwhile to highlight how this bracelet attaches to the case. There are no integrated end-links; instead, the proximal links are welded to a hollow bar through which the spring bar is inserted. This design leaves a bit of a gap between the bracelet end and the case that also provides a unique look.

SRPD75 Movement: Seiko 4R36

The Seiko SRPD75 is powered by a Seiko 4R36 self-winding movement. The 4R36 is a Seiko-manufactured caliber that possesses 24 jewels, 41 hours of power reserve, and +45s/-35s per day of accuracy.

Some other functions of this movement worth mentioning are a hacking seconds feature and the ability to hand-wind through the crown, two features that were absent in the SKX models that the 5 Sports are intended to replace.


The movement may be admired fully through the transparent case back. I also noticed that Seiko chose to use a brushed finish on the movement components that are visible. This is a refined detail that can hardly be expected at this price point.

Nevertheless, Seiko evidently considered it critical to dress up their movement to a certain degree if it was to be in direct view of its owner. It’s a small but refined detail that surely endears me to this watch if not the brand as a whole.

Seiko 5 SRPD75 Final Thoughts

An uncommon color choice, skillful bracelet selection, smooth case profile, and perfect legibility make this Seiko 5 sports SRPD75 an impressive watch for the price. I may be biased at this point since I’ve become quite acquainted with the SRPD75, but I’m not sure there’s better value to be had in this price category.

Admittedly, the green of this SRPD75 initially reminded me of a Rolex Hulk, and while the two are leagues apart in price, this may still scratch that itch if you don’t have a spare $25k to drop on a pre-owned Hulk.

Even if you feel the green theme isn’t for you, there are other color schemes with the same architecture within the collection that will surely catch your eye. Undoubtedly, if you were even a little intrigued by the SRPD75’s looks, I am sure you will be more than happy getting one on your wrist.
