The Seiko timepiece collection features the iconic logo across a multitude of designs, from chunky masculine automatic watches to futuristic technological designs, slim and delicate ladies' bands to sparkling fashion pieces and much more. For a watch that guarantees accuracy for everyday use to a gorgeous yet practical occasion accessory, Seiko's attractive designs will complete your look no matter what your personal taste or style. The markers and hands are filled with Seiko’s LumiBrite lume and will glow just as fantastically as any other Seiko you have seen. If you’re not familiar with Seiko lume, it will glow brightly at the slightest touch of light and last for hours. If they simply refreshed the SKX with the 4R36, people would have been ecstatic.

This watch looks and feels more like the Seiko 5s I have been accustomed to over the years with a few welcome upgrades. The 4R36 movement and larger crown are the biggest upgrades from previous generations of Seiko 5 models. The push/pull crown also feels more at home on this model than it did on the 5KX. There were droves of Seiko fans who went ballistic over the fact the 5KX had a push/pull crown. They wanted an SKX replacement and the inaugural Seiko 5 launch wasn’t it. If Seiko had started with this model and introduced the 5KX later, I think fans would have been more lenient on Seiko (although knowing Seiko fans this is somewhat doubtful). The 5KX would not have come across as an SKX downgrade but rather an evolution in the line. Everett’s Take on the Seiko 5 When comparing the SRPE to the SKX however, the difference is glaringly obvious - most of the Seiko SKX mod parts are not cross-compatible. Concluding this article, it’s safe to say that the Seiko 5 SRPE55K1is a watch that offers great value for money. The watch has a sporty appeal to it, but is still classic and refined to make it suitable for formal occasions, too. First, we want to make it clear that when we refer to the SRPE, we talk strictly about the Seiko 5 Sports series of watches. We state this as the SRPE model prefix is also used for Seiko Samurais. As an outlier; the SRPE83K1, which is also part of the Seiko 5 Sports Sense collection, is actually compatible with SKX007 parts.

Seiko 5 SRPE55 In Motion

Training load monitoring is typically an attempt to quantify two interrelated relationships: the training load–performance relationship (TL-P) and training load–injury relationship (TL-I) [ 1]. Both of these relationships appear to be quadratic whereby if too much or too little training is completed, there is a higher likelihood of not performing well or becoming injured/ill [ 1, 2]. There are two general TL constructs: internal and external. These constructs, along with their interaction, have been described previously [ 1– 4]. In practice, methods of monitoring TL vary considerably depending on the type of sport or activity [ 3]; however, TL models are commonly analyzed using training impulse, which is normally a product of an intensity factor and volume/duration factor [ 2, 5]. Frankly, there is nothing else to say about the watch – just look at that thing. I’m crazy about it. I love it. I’m head over heels. It’s so many of the things I love about the SKX in a watch that doesn’t feel like a huge, cheap, compromise. That’s not to say it’s perfect, or that I can’t find things to complain about (cough… cough… bracelet), but this is such a major improvement over what we all expected Seiko to serve us that I’m inclined to just give praise where praise is due. If Seiko had just started here, maybe then in a year or so, when they release 7,000 versions of a dumbed-down SKX with dials straight from Mortal Kombat sprites, we would be ready for it. The applied markers are simple yet slightly decorative at 12, 6, and 9. Those familiar with Seiko divers like the SKX will recognize their shape immediately. The triangle with an elongated point at 12 and the two elongated circles at 6 and 9 allow for instant orientation and add a touch of flair to the dial. As one would expect on any Seiko 5, a day/date complication is present at 3.

The movement has a specified accuracy of +45 / -35 seconds per day. This is not too bad, but owners have reported a much better accuracy in practice. In addition, if you want even better accuracy, it is possible to have a watchmaker regulate it. While not everyone actually takes their watch diving in deep waters, knowing that your watch is capable of 200m was a bragging right. Much like how computer GPU brands brag about how much VRAM their newest model has, or how many megapixels Samsung phone cameras can shoot, the water resistance rating was a big talking point for dive watches. The size hits a sweet spot of 42.5mm too, which is a great size for most wrists and doesn’t look overly large - a common theme with diving watches. A small detail to mention is the crown position at 4, making it more comfy to wear as the crown and crown guard will not directly hit your wrists. The hands and dials are extremely legible, and the simple chapter ring complements it quite nicely. The sideways 5/S logo is featured prominently under the main Seiko brand. The case is a mix of polished and brushed to help lessen the glistening effect which can be distracting for a sports watch. It still features Seiko’s good ol’ hardlex crystal, which is now mounted right on the bezel instead of within it.The SRPD and SRPE lines are more appealing to the new generation of watch collectors, with their more sleek and minimalist constructions and variety of OEM designs, not to mention the collaborations with other pop culture brands. They have a clear vision and demographic in mind for the Seiko 5 Sports, and we believe it can succeed despite the persisting demand for the SKX. The dial has a slightly matte finish which, in my opinion, makes it more interesting. An everyday watch with dive inspiration also needs great legibility, and this is something that it has too. After all, the dial is identical to the new Seiko diver, so expect nothing less than exceptional legibility. The silver bracelet of the watch is made from highly durable stainless steel, that has been finished using a brushing technique. This creates a subtle, but welcomed, contrast between the polishing of the case and the brushing of the bracelet. It comes in the style of an oyster bracelet, which is associated with the Rolex brand. It fastens usinga three fold clasp. The Dial:

Leather strap watches tend to fit without a problem for most wearers. However, watches fitted with metal bracelets often need adjusting to get the perfect fit. After spending some time with this watch, I concluded that if Seiko were going relaunch the Seiko 5 line, they should have started with this watch and not the 5KX. This watch makes so much more sense in the Seiko 5 line than the 5KX. Not that the 5KX doesn’t belong in the Seiko 5 line; Seiko has always included dive-style watches in the 5 line. It doesn’t make sense to start with the 5KX. If it weren’t clear, I like the change—I love the change. I think it ties the case together: look at how the polished tops of the crown guards finally have a friend to play with, instead of some itinerant, everchanging rotation of numbers that always seem a little off. Thankfully Seiko decided to give the SRPE55 100 meters of water resistance. This made me feel comfortable doing just about anything with it. I had no issues getting it wet or submerging it in water. The beefy crown guards made me feel secure enough to not have to worry about the crown popping out accidentally. The Seiko community, and yes, not just the modders, let out a collective sigh of disappointment when the SKX line of divers was discontinued. It has been a popular choice during its run, and became a household name for price-conscious divers watch fans.We’ve spent quite a bit of time here at Worn & Wound documenting the relaunch of the Seiko 5 Sports line (see news of the original announcement here , and Ed Jelley’s in-depth review here ). With so many new models coming to the market, as well as the implications of what it means to replace the beloved SKX007 and related models, this release was easily one of the biggest of the year in terms of its importance on the market as it relates to the watches we cover here. Now, almost a year after we first learned of the new Seiko 5 Sports series, we’re seeing the first new additions that represent the first move away from the very obvious diver aesthetic we’ve come to know. Think: Seiko 5 Sports, but without the bezel, and you have a pretty good idea of what’s in store. Seiko is a great place to start for someone who either just wants a great timepiece at an affordable price, or for someone who wants to dip their toes in the world of watches, in particular mechanical watches. In addition to that, a popular start is the Seiko 5 collection, which includes sporty and robust timepieces. Naturally, I was thrilled when Seiko announced the newest additions to the Seiko 5 Sports line, sans rotating bezel. Let’s just get the specs out of the way, since they’re pretty much perfect:

In terms of moddability, the SRPE Seiko 5 Sports watch is still very much in the discovery phase. People are just starting to experiment with it as a modding base, and not a lot of suppliers offer parts for the as of yet. But, while the steel sports watch craze has seemed like the story in watches over the last couple of years for us close enough to care, that is, of course, not the case. The larger story is the existential threat to the watch industry that comes in the form of a sleek glass squircle. If you've always been a fan of the Seiko diver but really never go near water, and let's face it, you've never even used the rotating bezel to time anything, then the Seiko 5 SPRE series is for you. They removed the bezel for a slimmer, cleaner look, and turned the classic diver watch into a kind of "dress diver."All this is to say that whatever the price point or collection, a Seiko (or a mechanical Seiko, at least) is something no watch snob will roll their eyes at. Pieces from the more affordable collections remain gateway watches. Countless people wearing Royal Oaks and Lange 1s will tell you the first mechanical watch they bought was a Seiko. In fact, some collectors only collect Seikos. It TRULY caught my attention For it charming goOd looks. Theres some about it that is purley seiko. namokiMODS does have a few parts available for SRPE modding already, starting with the case. If you don’t wish to buy a brand new watch just to take it apart and build a new one, you can always start with a bare modding case, like our Polished SRPE Pilot Case . It already comes with a matching bezel and crown to make it easier to work with!
