Introduction

Let's cut to the chase: the Naoya Hida NH Type 2A isn't just a watch—it's a flex for the guy who already owns a Royal Oak and a Nautilus but wants something that screams 'I know things you don't.' In the hyper-saturated world of luxury dive watches, where every brand is reissuing its '60s catalog, this independent Japanese maker has carved out a niche that's equal parts horological purity and investment-grade rarity.

I've tracked the secondary market for three years now, and the Type 2A has done something most independents can't: it's appreciated steadily, even through market corrections. That's not hype; that's data. With production capped at around 50 pieces per year and a waiting list that stretches past your patience, this isn't a watch you buy on a whim—it's a watch you buy to hold, wear, and eventually flip to a younger collector who missed the boat.

But let's not pretend it's all about the money. The Type 2A is a love letter to vintage dive watches, executed with a level of hand-finishing that rivals brands three times the price. It's a paradox: a tool watch that's too pretty to actually dive, yet robust enough to survive the urban jungle. In this review, I'll break down the specs, the movement, the wrist presence, and most importantly—the resale curve—so you can decide if this is the next addition to your portfolio.

Manufacture History

Naoya Hida is a name that's been buzzing in the independent watch community since 2018, when the Tokyo-based watchmaker released his first piece, the NH Type 1. Hida's background is in restoration—he spent years bringing vintage Seikos and Grand Seikos back to life, which gave him an intimate understanding of what made those watches so special. His goal was to create a modern watch that captured the soul of those classics, but with a level of finishing that would put Swiss heavyweights to shame.

The NH Type 2A, introduced in 2020, is his take on the classic '60s dive watch—think cushion case, domed crystal, and a gradient dial that shifts from blue to black. It's a design that's been done before, but Hida's execution is what sets it apart. Every case is hand-polished using the zaratsu technique, a method that requires hours of painstaking work to achieve a distortion-free mirror finish. The dials are produced in small batches, with applied indices that are individually polished and aligned. It's this obsession with detail that has earned him a cult following among collectors who crave something beyond the mass-produced luxury of big brands.

Today, Naoya Hida operates as a one-man show, with a small team of artisans in his Tokyo atelier. Production is deliberately limited to ensure quality, and each watch is assembled, regulated, and tested by Hida himself. This is not a brand that will ever be sold in a boutique; it's a brand that you discover through word of mouth, and that's part of its allure.

Movement

Powering the NH Type 2A is a heavily modified Miyota 9015 automatic movement. I know what you're thinking—a Japanese movement in a Japanese watch? It's a logical choice, but Hida doesn't just drop it in and call it a day. He strips it down to its base plate and rebuilds it with hand-finished components that elevate it to haute horlogerie levels.

The bridges are bevelled by hand, with a mirror polish that catches light like a diamond. The rotor is custom-made, engraved with the Naoya Hida logo and finished with a sunray pattern. The balance wheel is free-sprung, which improves timekeeping stability, and the entire movement is regulated in six positions. The result is a movement that, while not in-house, performs and looks like something from a Swiss independent. Power reserve is a modest 42 hours, but that's typical for a movement of this architecture, and it's not a dealbreaker for a dressy daily wearer.

Accuracy is excellent—my test unit ran at +3 seconds per day, which is better than many COSC-certified movements. The hacking seconds and hand-winding capability are retained, and the crown action is smooth and precise. It's not a movement that will win awards for innovation, but it's a movement that's been perfected through careful modification, and that's exactly what you want in a watch at this price point.

Specifications

The 37mm case is a deliberate choice—it's a nod to the vintage divers of the 1960s, which typically measured 36-38mm. On a modern wrist, it might seem small, but the cushion shape and the pronounced lugs give it a presence that belies its size. The domed sapphire crystal is a nice touch, adding a subtle distortion that mimics the look of acrylic. Water resistance is rated at 100m, which is more than enough for swimming and snorkeling, but it's not a true dive watch—the lack of a screw-down crown (it's a push-pull) and the leather strap make that clear. However, if you're a collector who cares about aesthetics over functionality, this is a non-issue.

Wrist Feel

On the wrist, the NH Type 2A is a revelation. The 37mm case wears larger than you'd expect, thanks to the broad lugs that curve down to hug your wrist. The weight is substantial—it feels solid and well-made, but not heavy. The leather strap is supple from the start, and the pin buckle is easy to adjust. The domed crystal sits above the bezel, which gives it a vintage feel and also protects the bezel from scratches. The crown is easy to grip, even though it's not screw-down, and the overall profile is slim enough to slide under a shirt cuff.

I wore it for a week straight, from morning meetings to evening dinners, and I never felt the urge to take it off. It's the kind of watch that disappears on the wrist—you forget it's there, but when you glance down, you're reminded of its beauty. The gradient dial is mesmerizing, shifting from deep blue in the center to near-black at the edges, and the applied indices catch light in a way that makes the dial look alive. It's a watch that invites you to stare at it, and that's a rare quality.

Accuracy

In real-world testing, the NH Type 2A performed admirably. Over a week of wear, I averaged +3.2 seconds per day, which is within the range you'd expect from a well-regulated automatic. The free-sprung balance helps maintain consistency, and I noticed no significant positional errors. If you're a stickler for precision, you can have it regulated to within a second per day, but it's not necessary. The movement is stable and reliable, and it's a joy to wind and set—the crown action is buttery smooth, and the hacking seconds make it easy to sync with your phone.

One thing to note: the power reserve is only 42 hours, so if you take it off on Friday night, you'll need to wind it on Monday morning. That's a minor inconvenience, but it's a trade-off for the thin case and the vintage styling. If you're a collector who rotates watches, you'll want to invest in a watch winder or just give it a quick wind before wearing.

Occasions

The NH Type 2A is a chameleon. Its vintage proportions and elegant finishing make it suitable for formal events—it pairs beautifully with a tailored suit. The gradient dial adds a touch of sophistication, and the hand-polished case catches light in a way that's understated but noticeable. At the same time, it's robust enough for daily wear, whether you're at the office or out on the weekends. It's not a sports watch in the traditional sense, but it can handle a bit of rough and tumble. I'd avoid wearing it for actual diving or extreme sports, but for a day at the beach or a round of golf, it's perfectly fine.

In terms of dress code, it works for both casual and formal. The leather strap can be swapped for a NATO or a tropic rubber strap if you want to dress it down, but the stock leather is already quite versatile. I found myself wearing it with everything from jeans and a t-shirt to a three-piece suit, and it never looked out of place.

Wrist Presence

I give the NH Type 2A a 4 out of 5 for wrist presence. It's not a loud watch—it doesn't scream for attention like a Hublot or a Rolex with a flashy bezel. Instead, it exudes quiet confidence. The dial is the star, with its gradient finish and perfectly executed indices. The case polishing is so good that it creates a mirror effect, but it's not over-the-top. People who know watches will recognize it as something special, but the average person won't give it a second glance. That's exactly what you want in a collector's piece—it's for you, not for the public.

The lume is also worth mentioning. Super-LumiNova X1 is bright and long-lasting, and the vintage-style hands and indices glow in a greenish-blue that's both nostalgic and modern. It's a small detail, but it adds to the overall experience.

Reference Variants

The NH Type 2A is part of a family of watches from Naoya Hida. The most common variant is the blue-black gradient dial, which I've reviewed here. There's also a Type 2B with a silver-white dial and different hand style, which is even rarer and often commands a premium on the secondary market. Both share the same case and movement, but the dial treatment and hand finishing differ. If you can find a Type 2B, it's worth considering as an alternative—it's a bit more dressy and understated.

Family References

Naoya Hida's lineup includes the NH Type 1 (a time-only watch with a more classic round case), the NH Type 2A and 2B, and the NH Type 3, which is a chronograph. Each model is produced in limited numbers, and they all share the same commitment to hand-finishing and vintage aesthetics. If you're interested in the brand, the Type 1 is a good entry point, but the Type 2A is the one that has captured the most attention from collectors.

Similar Watches

If you're considering the NH Type 2A, you might also look at the Grand Seiko SBGW231, which offers similar hand-finishing but with an in-house movement and a more accessible price. The Omega Seamaster 300 Heritage is another option, though it's larger and more modern. And if you want to go upmarket, the Blancpain Fifty Fathoms is the original dive watch, but it's significantly more expensive. The NH Type 2A sits in a sweet spot—it's more exclusive than the Grand Seiko, but more affordable than the Blancpain.

Homages

For those on a budget, there are several homages to the NH Type 2A's design. The Seiko SRP777 is a classic cushion-case diver that costs around $300, and it captures the vintage vibe without the hand-finishing. Steinhart's Ocean One Vintage is another option, with a similar case shape and a reliable ETA movement. These won't give you the same level of craftsmanship or investment potential, but they're great entry points into the style.

Investment Value

Let's talk numbers. The NH Type 2A has an MSRP of $8,500, but due to its limited production and high demand, you'll likely pay closer to $9,500 on the secondary market if you can find one. Pre-owned examples are currently trading between $8,500 and $12,000, with the higher end reserved for unworn pieces with box and papers. The trend is clearly upward—early adopters who bought at MSRP have seen their watches appreciate by 20-30% in just a few years. This is driven by the growing interest in independent watchmakers, especially among young collectors who want something unique.

My recommendation: if you can get one at MSRP, buy it. If you have to pay a premium, it's still a reasonable investment, but you'll have less room for profit. Hold it for at least 3-5 years, and you'll likely see continued appreciation. The production cap of 50 pieces per year means supply will always be tight, and as the brand's reputation grows, so will demand. I've seen auction results at Phillips and Christie's where the Type 2A fetched between $10,000 and $14,000, and that's a trend that's only going to continue.

Service and Maintenance

Like any mechanical watch, the NH Type 2A requires regular servicing every 5 years or so. The cost is around $600, but you'll need to send it back to Naoya Hida's workshop in Tokyo, which can take 3-4 months due to the waiting list. It's not convenient, but it's necessary to maintain the watch's value and performance. The good news is that the movement is based on a Miyota, so any competent watchmaker can work on it, but for the full hand-finishing touch, you'll want to go to the source.

Final Verdict

The Naoya Hida NH Type 2A is a masterpiece of independent watchmaking that bridges the gap between vintage charm and modern investment potential. It's not for everyone—the small size, the waiting list, and the price tag will filter out the casual buyer. But for the collector who values craftsmanship and understands the market, this is a piece that will only grow in desirability. Wear it, love it, and watch it appreciate.
