The dust has settled down. Meanwhile, a large portion of us are utilized to the way that Seiko doesn’t supply its gigantically famous SKX 007 and SKX 009 models any longer. When paying attention to mechanical diver’s watches, if conceivable by any means, what are your choices in Seiko’s current line-up of programmed diver’s watches?

Starting with the Seiko SKX 007/9 USP’s

First, to conceivably come up with choices, let’s have a glance at the SKX’s details and USP’s (Unique Selling Points). I’ll start with its – for a diver’s watch – a moderate size of 42,5 mm. Although individuals with a little size wrist, say under 17 cm, will think this is rather huge. On account of the SKX, it isn’t. Also, that’s most likely fundamentally due to the exceptionally moderate haul to carry distance of 46 mm. Indeed, even on a little wrist, it won’t hang over rapidly and will demonstrate to fit very well. The situation of the watched screw-down crown at 4 o’clock is another component encouraging a comfortable fit.

I’ve never seen Seiko publicize the SKX 007/9 as being ISO 6425 ensured. In any case, indeed, it should have been confirmed. The SKX is endorsed with ‘Diver’s’ in the dial, complemented with ‘200m’. A watch made in an ISO-compliant nation (like all nations the Seiko SKX was created) and marked ‘Diver’s’ should have experienced the suitable ISO 6425 test. To comply with ISO 6425, this infers that each and every delivered SKX watch – not only a couple tests – should have been pressure tried. Which I can envision wasn’t done.

And to wrap things up, the alluring cost. While the most recent realized rundown cost of the SKX007 and 009 models were in the € 400,- area, it’s no mysterious that the road or going-costs were not so much as 3/4 of that. Being entirely moderate, for some, it was their first experience with a programmed wristwatch.

And what about the Seiko SKX that wasn’t that good?

A part of inspiration, obviously, there were some negative focuses about the SKX too. It was for the most part the 7S26 type, which was let’s say, somewhat obsolete. Still dependable as could be, however with guaranteed precision resiliences that were not comparable to these days principles. Too, the development couldn’t be twisted by hand, and one couldn’t stop its second hand to set the opportunity to the second precise. Likely in light of these reasons, and on the grounds that the SKX wasn’t ISO 6425-ensured (I surmise), Seiko intended to stop creation and spotlight on diver’s watches with higher in general standards.

Which models will cause us to fail to remember the SKX?

Let’s make first evident that now all mechanical diver’s watches in Seiko’s line-up are ISO 6425 affirmed. So every Seiko Diver’s watch you can purchase presently has been pressure tried. No wasting time with something important as a diver’s watch. Furthermore, all diver’s watches currently utilize more precise developments which can be twisted by hand, and have a second-hack work. To emphasize this, all of Seiko’s Diver’s watches are presently Prospex (Professional Specifications) logo-signed.

So which watches in the current line-up of Seiko diver’s watches could we take a gander at to fail to remember the SKX? That will rely fundamentally upon which portion of the SKX was fundamental for you. For example, was it the size, the crown at 4, its appealing cost, or in any event, something else?

In this outline, I’ll list the, as I would like to think, most essential adaptations of the distinctive Seiko diver’s watch models, generally near the SKX007. For example watches with a dark dial and dark turning bezel. Remember that Seiko makes the majority of these watches accessible in many (shading) varieties; it’s up to you which one you like most. Let’s start now with a watch pretty much equivalent in size and rundown cost of the SKX.

1. The Seiko SRPC35, otherwise known as ‘Mini-Turtle’

With its 42,3 mm width (the bezel just estimating 39 mm) and 13 mm thickness, the size of this watch’ packaging is pretty much equivalent to the SKX. The shape is extraordinary, though, and it positively appears to be more modest. In particular, the non-monitored crown at the ordinary 3 o’clock position isn’t SKX-like.

Further, the SRPC35 houses the 4R35 type, which sports a day sign just, yet no day and date. Something I for one highly appreciate at diver’s watches, however I’m mindful that others do like a day and date. Particularly when the date sign is in Kanji 😉

The list cost of this watch, including the (20 mm carry width) hardened steel arm band, lies around € 440,- , so that’s pretty equivalent to the previous SKX. It appears to be that this model isn’t accessible on the whole European nations, though, and I’m not even secure with the US.

2. The Seiko SRPB51, otherwise known as ‘Samurai’

Another watch with a significant equivalent size and cost. 43,8 x 13,4 mm and a rundown cost of around € 450,= including (22 mm) hardened steel wristband. Here we do discover crown-watches, yet at the same time, the crown at the 3 o’clock position.

Same date-just 4R35 type, this time without the amplifying bubble in the Hardlex precious stone. The diverse style of case, dial, and hands will choose if you like one over the other. While the ‘Mini-Turtle’ might have a more traditionalist plan, the instance of the ‘Samurai’ absolutely gains regard being more present day. Also, the ‘Samurai’ is overall more generally accessible than the ‘Mini-Turtle.’

3. The Seiko SRP777, otherwise known as ‘Turtle’

We’re drawing nearer now. This ‘Turtle’ has it’s crown at 4 o’clock, and keeping in mind that it’s so coordinated into the shape of the packaging, it can even be viewed as secured. Too, the SRP777 ( we did an audit here ) houses a 4R36 type, which implies day and date. Additionally, the rundown cost of around € 400,- (on 22 mm elastic lash) comes near the authority list cost of the SKX. This variant with a matt dark dial doesn’t appear to be accessible on a treated steel wristband, nor is it accessible taking all things together European countries.

Here the size of the watch most likely heightens somewhat wild. With an extreme 45 x 13,4 mm, this watch might not be for everybody. Although I should say on my 17,5 cm wrist, it wears fantastic and incredibly comfortable. It’s expected to be brought about by the amazingly short drag to haul distance, and I can envision that. As far as I might be concerned, this watch, with its exemplary dial, record markings, and hands-set, is a genuine competitor to supplant a SKX.

4. The Seiko SRPD27, otherwise known as ‘Monster’

We’re getting to the last Seiko Diver’s watch in this value alliance (list cost € 450,- on 20 mm elastic lash). Again the crown at the 4 o’clock position and again the 4R36 day and date type. This time with a huge air pocket, or loupe, in the Hardlex glass for better clarity. Too, this watch, with its size of 42,4 x 13 mm, is reasonable for some wrists.

But. The ‘Monster’ didn’t get its epithet for anything; it appears to be very unique from some other Seiko Diver’s watch. It’s likely not the dial; however, the bezel has something about it. It doesn’t have a dark trim. However, it’s is all dark PVD’d. Together with the advanced hands-set, and a specific drag shape, this watch must be adored or hated.

What else is good?

Although I discovered my SKX replacement in the SRP777 ‘Turtle’, what in the event that you didn’t discover yours? The uplifting news is I discovered some more, and likely far better, choices in Seiko’s line-up of programmed Diver’s watches. The awful news is, it’s going to set you back more than twice the measure of the Seiko SKX007.

5. The Seiko SPB101, otherwise known as ‘New Sumo’

We’re step up here. Obviously, not simply the rundown cost (€ 830,= on a 20 mm hardened steel wristband with fine change plausibility) however satisfactorily on further details also. For example, the considerably more precise 6R35 type supplies a whopping 70 hour of force hold. Compared to the 41 hours of the 4R3X types of the four watches shown previously. The 6R35 is a date-just development, yet as said, I like that for a diver’s watch.

What else is better? Indeed, rather than the Hardlex gem seen on the over four models – a Seiko home-developed hardened kind of mineral glass – the ‘New Sumo’ sports sapphire gem. On the off chance that cash were no issue, I’d presumably favor this SPB101 over the SRP777, although I’m not certain I like it twice so much. One purpose of concern could be the generally little 20 mm drag width compared to the rather huge 45 mm casing.

6. The Seiko SPB077, otherwise known as ‘MM200’

First, I need to clarify this watch’s epithet. The famous Seiko Marine Master 300 , which was presented as SBDX001, then refreshed to SBDX017, and now to SLA021 (I’ll get to this one later) has consistently been scratched ‘MM300’. MM for Marine Master and 300 being its depth rating of 300 meters. It has to be said that the SPB077 we’re discussing here, does as it were, resemble the MM300. While the SPB077 has a depth rating of 200 meters, and although not a Marine Master by any means, it’s straightforward it got scratched MM200.

The SPB077 houses a 6R15 type that doesn’t supply a 70 like the SPB101, however a 50-hour power save. Once more, it’s a date in particular. The 44 x 13 mm packaging can be viewed as sufficient, while here too, a 20 mm carry width appears to be a piece crampy. A positive point is the outrageous hard Diashield covering, which Seiko utilizes on this model to maintain a strategic distance from day by day minor scratches from wear. Obviously, this watch sports a level sapphire precious stone also. The rundown cost of the SPB077 lies around € 1.050,- .

7. The Seiko SPB051, otherwise known as ’52MAS’

Another higher-end diver’s watch utilizing the 6R15 type. A completely unique plan from the previous two watches recorded here, this time with the crown at the 3 o’clock position, and without monitors. The shape of the case is actually similar to Seiko’s first historically speaking Diver’s watch (1965), the 6217-8000/1 or  62MAS . In 2017 Seiko presented with the SLA017 (8L35 development) a genuine re-version of this first jumper ever. Close by this 2000 pieces restricted version, the SPB051 with its 6R15 type was presented as a more moderate option too. While the SLA017 was the genuine re-translation of the 62MAS, the SPB051 turned out to be flippantly known as the ’52MAS’. A moniker not broadly spread, though.

The sapphire precious stone on this model is slightly bended, and the 42,6 x 13,8 mm tempered steel packaging (carry width 20 mm) exploits the hardened Diashield covering too. The rundown cost of the 52MAS is equivalent to the ‘MM200’, € 1.050,- .

8. The Seiko SLA021, otherwise known as ‘MM300’

Under point 6, I previously referenced returning to this SLA021, the furthest down the line posterity to the colossally famous MM300 models. Before you head off to your closest Seiko seller, I need to communicate that this watch – with its rundown cost of € 3.200 – is in an alternate alliance and not the slightest bit to compare to anything referenced here above. However. However, it’s a Seiko Prospex Diver’s watch, thus I didn’t need to avoid it with regard to this overview.

You’ll comprehend that in this class, we’re discussing various watches with various same determinations. Here we go. Rather than the wide range of various referenced models being 200 meters appraised, the SLA021 has a depth rating of 300 meters. Not that anybody of us would even think about jumping to a depth of 200 meters, not to mention 300 meters. So what’s the point? The fact is that Seiko adopted a whole extraordinary strategy to reach this rating. Furthermore, too, on the grounds that a depth rating of 300 meters implies an alternate approach to plunging, this watch is appropriate for immersion jumping. In the event that you’re curious about the term; Jack Forster, over at our Friends of Hodinkee, nailed it with “

I don’t need to dive excessively deep into the details of the SLA021, as Robert-Jan previously did a superb survey of this watch . I’ll just rundown the principle contrasts, other than its value level, to the other seven watches in this outline. Monobloc packaging, which implies the watch has no removable case back. 8L35B development, equivalent to Grand Seiko’s 9S55 (yet with lesser finish). Artistic turning diver’s bezel. Zaratsu polished packaging with DiaShield covering. Sapphire gem. Seiko marked this watch as ‘Professional’ rather than ‘Diver’s.’


Although we comprehend that it’s hard to bid farewell to a friend or family member, I think we’ve shown here that Seiko had valid justifications to end the creation of the SKX 007 and 009. What’s more, we clarified that, even in a similar value group, there’s a lot to choose from in the current Seiko Diver’s line-up.
