Seiko SLA085J1 Review – Hands-On with the King Seiko Vanac "Tokyo Midnight"
Hey Watchfam – meet the Tokyo Midnight
Every now and then, a watch lands in that just feels different. The Seiko SLA085J1, part of the revived King Seiko Vanac line, is one of those pieces. As soon as I got it on wrist, I knew this was something special. It’s sharp, bold, and packed with heritage — yet still feels fresh and modern.
Nicknamed Tokyo Midnight, the SLA085J1 is inspired by the deep blues of Tokyo’s skyline at night. It forms part of a broader Vanac revival, but for me, this is the standout — both in terms of visual punch and real wrist presence.
First Impressions – On wrist and in hand
Straight out of the box, the 41mm angular case demands attention. The sharp facets, the interplay between mirror polishing and brushing — it feels carved, sculpted, almost architectural. Yet despite those bold lines, the case doesn’t wear awkwardly. At 14.3mm thick and 45.1mm lug-to-lug, it sits beautifully on my 7” wrist.
But what really surprised me is just how special this feels on the wrist. I’ve owned and tested a lot of Seikos, but this? It feels a cut above. There’s a refinement in the finishing, the precision of the lines, and the way the light plays across the surfaces that tells you Seiko went the extra mile here.
The bracelet plays a big part in that. It’s a new design specific to the Vanac — broad, flat links with alternating brushed and mirror finishes. It feels premium, it wears comfortably, and it flows nicely with the case. That said, I do think it could have benefited from a micro-adjustment option. I was able to get a good fit, but some will want that extra fine-tuning for the perfect wear.
Then there’s the crown — a real standout for me. It’s nicely sized, grippy, and just feels good in the hand when winding. My only wish? I’d have loved to see a KS engraving on the crown. It’s a small detail, but one that would’ve added an extra nod to the King Seiko heritage.
The dial – Tokyo skyline at midnight
The dial is where this watch really comes alive. The deep navy base, paired with the horizontal striping, gives it a texture and depth that shifts with the light. In bright conditions, it flashes a vibrant blue; in the shadows, it’s darker, moodier — very much like Tokyo at midnight.
Framing the dial is a recessed ring where the applied indices sit, adding layers of depth and structure. The 12 o’clock index forms a ‘V’ shape, a nod to the Vanac name, and the seconds hand counterweight mirrors that same motif — little details that quietly elevate the design.
I know some people will bemoan the date window at 3 o’clock, but honestly? I found it unobtrusive and well-integrated. It doesn’t throw off the symmetry and it adds practicality without compromising the aesthetic.
Another feature I’m a huge fan of is the no-bezel design, paired with the proudly domed sapphire crystal. It gives the watch a striking side profile that’s both vintage and modern at the same time.
Movement – Seiko’s 8L45 under glass
Flip the watch over and you’re treated to a see-through caseback, a first for the King Seiko line since its relaunch in 2022. Through the sapphire window, you can view the 8L45 automatic movement, a calibre built at the esteemed Shizukuishi Watch Studio — the same facility that produces Grand Seiko movements.
Specs-wise, it runs at 28,800 vph, has 35 jewels, and delivers a 72-hour power reserve. Seiko rates it at +10/-5 seconds per day, and in my wear, it’s sat comfortably within those parameters. Winding is smooth, the crown action is solid, and it feels every bit a premium calibre for this price bracket.
No, it’s not as elaborately finished as a Grand Seiko movement, but it’s clean, robust, and has a purposeful beauty when viewed through the back.
Real-world experience – Character and comfort on wrist
The more I wore the SLA085J1, the more I appreciated its personality. The way the case catches and reflects light gives it an almost jewellery-like quality, but without being showy. It has that perfect sports watch that dresses up well vibe — exactly the kind of dual-role piece I think a lot of collectors seek out.
Comfort: The bracelet is a win. It wears well, feels secure, and stays comfortable all day. But yes — a micro-adjust would have made it even better.
Wrist presence: Absolutely superb. At this price point, I’m struggling to think of another watch that delivers this kind of visual impact with heritage baked in.
Lume: The LumiBrite does the job. You’ll get enough visibility in the dark, but it’s subtle — not overdone.
Water resistance: 100m with a screw-down crown — safe for everyday life.
Magnetic resistance: 4,800 A/m, so it’ll shrug off daily tech exposure.
Overall, this watch feels fun, characterful, and premium — all the things you want when stepping up to this price tier. It’s absolutely a piece I’d love to keep in my collection long-term.

Final thoughts – A premium revival done right
Seiko absolutely nailed this one. The SLA085J1 feels more special on wrist than any Seiko I’ve owned or tested before. From the crisp case finishing to the engaging dial, and that strong wrist presence, it’s just a brilliantly executed watch.
For collectors or enthusiasts looking for a sports watch that can easily dress up, or for those wanting something different from the usual divers and dress pieces, this is a winner. I also think this entire Vanac line is going to be a big hit for Seiko, particularly with those who love a bit of retro flavour served with modern specs.
