Two Watches, One Anniversary

Seiko turned 145 in 2026, and rather than mark the occasion with a single flagship release, the Presage Classic Series quietly put out two. Both were announced on May 14, 2026, both borrow the accent color Seiko calls “Seiko Blue” — the brand’s own signature hue, refined since the 1960s — and both share the exact same automatic movement. Where they diverge is craft and price. The HCC007 is the harder, more expensive flex: a dial made from real Arita porcelain, fired and glazed by a master craftsman in Japan, in a cobalt blue color never before used on a Presage. The HCC004 is the more wearable, more attainable companion piece: a smaller 36mm case with a dial whose radial texture is meant to evoke raw silk yarn, finished in a soft, immaculate white called shironeri.

Neither watch has appeared in a dedicated comparison anywhere online as of this writing, despite both already shipping to US retailers — the HCC004 since June 2026 and the HCC007 since July 2026. That makes this the first real head-to-head on which of Seiko’s two 145th Anniversary Presage pieces is the better buy.

HCC007: Arita Porcelain in Cobalt Blue

The HCC007 is built around a genuine Arita porcelain dial, a craft with roots in Japanese ceramics dating back to 1830. Under the supervision of Arita porcelain master craftsman Hiroyuki Hashiguchi, kiln team leader Toshiaki Kawaguchi and his team mold, glaze, and fire each dial individually at a historic manufacturer in Japan. This is the first time Presage has used a cobalt blue glaze — a traditional Arita hue — and getting it right on a dial this thin was, by Seiko’s own account, an unprecedented technical challenge: the glaze had to be balanced so the dial’s finely molded radiating pattern stays visible without either washing out or overwhelming the color underneath. Because each dial is hand-fired porcelain rather than a printed or stamped surface, small dimples, tiny dots, and minor unevenness are normal, and no two dials are exactly alike.

The case is new for this piece: a 39.6mm stainless steel case with a super-hard coating, paired with a dual-curved sapphire crystal that has anti-reflective coating on the inner surface only, keeping the porcelain’s color and depth visible without a distracting glare. It’s a genuinely dressy proportion — 12.8mm thick, 46.8mm lug-to-lug — finished with a cow leather strap sourced from Leather Working Group-certified tanneries and a three-fold clasp with push-button release. Water resistance is a modest splash-resistant rating only, which is typical for Presage’s dressiest dial-craft pieces and not a knock against the watch; this isn’t a piece meant to see a sink, let alone a pool.

Inside is Seiko’s Caliber 6R51, an automatic movement with manual-winding capability, a 72-hour power reserve, 24 jewels, and a stop-second hand for precise time-setting. It’s accurate to +25/-15 seconds a day — solidly mid-tier for a mechanical Seiko caliber, not chronometer-grade, but perfectly serviceable for a dress watch that’s more about the dial than the regulation. Only 1,500 examples exist worldwide, and the case back is stamped accordingly, with a see-through screw case back showing the movement.

HCC004: The Silk-Inspired Shironeri Dial

The HCC004 takes the opposite approach: instead of a labor-intensive ceramic dial, it leans on texture and proportion. Its dial color is inspired by shironeri, a traditional Japanese term for the immaculate white produced by refining raw silk threads, and the surface itself carries a fine radial pattern meant to evoke the texture of silk yarn catching light. The hands and hour markers are gently curved to follow the dial’s contour and finished in a blue tone pulled from the same “Seiko Blue” accent as the HCC007, giving the piece a quiet contrast against all that white.

Where the HCC007 goes bigger, the HCC004 goes smaller and softer: a 36.0mm stainless steel case with soft, flowing lines, just 12.5mm thick and 41.4mm lug-to-lug — genuinely compact by current dress-watch standards, and easier to wear for anyone without a large wrist. It shares the same dual-curved sapphire crystal with inner anti-reflective coating, the same LWG-certified leather strap (in a deep navy rather than the HCC007’s tone), and the same three-fold push-button clasp. Water resistance is actually the better of the two here at 10 bar (100m), a meaningful practical upgrade over the HCC007’s splash-only rating even though neither watch is meant for serious water exposure.

The HCC004 uses the identical Caliber 6R51 found in the HCC007 — same 72-hour reserve, same 24 jewels, same +25/-15 second accuracy — so the movement isn’t a point of differentiation between the two at all. What differs is the limited-edition count: 2,500 pieces globally, considerably more generous than the HCC007’s 1,500, which in practice means slightly better availability and a lower risk of missing out entirely.

Where the Ongoing Craftsmanship Series Fits In

The HCC007 and HCC004 aren’t Presage’s only current artisan-dial pieces, and buyers who miss out on either limited edition have a reasonable fallback. Seiko’s ongoing “Craftsmanship” line — not tied to the 145th anniversary and not limited-run — includes the HCC005 ($1,400), with a genuine enamel dial fired at high temperature, and the HCC006 ($1,650), with a hand-applied urushi lacquer dial, both due to release in September 2026. Both use a slightly different Caliber 6R5H rather than the HCC007/HCC004’s 6R51 — functionally similar, but with an added 24-hour hand for a subtle GMT-style reference — and both share the same 39.6mm case dimensions as the HCC007.

That makes for a genuinely confusing four-watch family if you’re shopping the Presage Classic Series dial-craft pieces without reading the fine print: two 145th Anniversary limited editions (HCC007, HCC004) and two ongoing Craftsmanship pieces (HCC005 Enamel, HCC006 Urushi) that share a design language but not a production run. If you specifically want the anniversary story and the rarer piece, it has to be the HCC007 or HCC004 — once those sell through, they won’t be replaced. If you simply want a hand-crafted Presage dial and don’t care about the anniversary angle, the enamel HCC005 or urushi HCC006 will likely remain orderable well past 2026.

How They Compare to Other Artisan-Dial Dress Watches

Hand-crafted dial techniques aren’t unique to Seiko, and buyers cross-shopping this segment should know what else occupies the same conversation, even if the price gap is real.

Watch	Price (2026)	What you’re paying for
Seiko Presage HCC004	$1,000	Silk-textured dial, 36mm, in-house 6R51
Seiko Presage HCC007	$1,700	Hand-fired Arita porcelain dial, 39.6mm
Nomos Tangente 38	~$2,220	German in-house hand-wound Alpha caliber, minimalist Bauhaus dial
Longines Master Collection 40mm	~$2,400-2,600	Swiss heritage design, ETA-based automatic, silver dial
Frederique Constant Manufacture Classic Date	~$3,495	In-house Swiss FC-703 automatic caliber, guilloché-style dial

Competitor pricing per official brand sources and authorised retailers, August 2026.

Neither Presage piece tries to compete with in-house Swiss manufacture movements at two to three times the price — the 6R51 is a solid, unglamorous workhorse caliber, not a Nomos Alpha or a Frederique Constant FC-703. What the HCC007 and HCC004 sell instead is genuine, labor-intensive Japanese dial craft — hand-fired porcelain, silk-inspired texture — at a fraction of what a comparably hand-finished Swiss dial would cost. That’s a different value proposition than “buy the best movement for the money,” and it’s the one Presage has built its entire Craftsmanship line around.

Which Should You Buy?

Choose the HCC007 if the Arita porcelain dial itself is the draw — it’s the rarer piece at 1,500 units, the more technically difficult dial to produce, and the larger 39.6mm case gives it more wrist presence for buyers who find 36mm too small. It’s also the pick if you specifically want the “first cobalt blue Arita dial on a Presage” story for a collection built around firsts and limited runs. For more on how Presage’s other collections stack up, our Seiko Presage Buying Guide covers the full lineup beyond just the Craftsmanship pieces.

Choose the HCC004 if budget and wearability matter more than dial rarity — it’s $700 cheaper, a genuinely compact 36mm that will suit smaller wrists far better than the HCC007, and its 2,500-piece run gives you meaningfully better odds of actually finding one in stock. The better 100m water resistance is a small but real practical upgrade too. Buyers who like the silk/porcelain craft angle but want to compare it against Presage’s other dressy references should also look at our Presage Cocktail Time Review and Presage Style60’s SRPL75 vs SRPL09 comparison for less expensive, non-limited alternatives in the same Classic Series design language.

Buyers deciding between Presage and a more affordable Swiss alternative should read our Presage vs Hamilton Khaki Field comparison, and those wondering whether to skip Presage entirely for Seiko’s higher-tier in-house dress pieces should see our King Seiko Buying Guide or Grand Seiko Elegance Collection Buying Guide as the next step up in craft and price.

Whichever one you land on, a few accessories are worth budgeting for. A soft leather strap conditioner kit keeps the LWG-certified leather strap from drying out and cracking over years of wear, a single watch winder keeps the automatic movement wound and ready without hand-winding every few days, and a padded travel watch case is worth having given how easily a hand-fired porcelain or lacquer dial could be damaged if it’s tossed loose into a suitcase.

Frequently Asked Questions: Seiko Presage HCC007 vs HCC004

Final Verdict

The HCC007 and HCC004 are two answers to the same question — how do you mark 145 years of Seiko history with a dial craft that says something real about the brand’s roots — and neither answer is wrong. The HCC007 is the more ambitious watch: a genuinely difficult, first-of-its-kind Arita porcelain dial in a color Presage had never used before, at a size that wears with real presence. The HCC004 is the more sensible one: a smaller, more affordable, more widely available piece that still delivers real handcraft in its silk-inspired dial texture, just without the porcelain premium.

If you can only choose one and rarity matters to you, buy the HCC007 while the 1,500-piece run lasts. If you want the anniversary story at a friendlier price and a case size that will actually get worn every day, the HCC004 is the smarter buy for most people. Either way, you’re getting a genuinely hand-crafted dial from a 145-year-old manufacture for well under what a comparable hand-finished Swiss dial would cost.
