ORENJI HACHI
About this product
What is the ORENJI HACHI? It's a deliberately playful collaboration watch between Swatch and ChromaTempo that reinterprets classic watchmaking with a confident wink at convention through its navy tapisserie dial and vibrant blue bioceramic case. As Cassia Varma, I've tested this exact model against seasonal color trends, and it delivers that rare combination of Milanese elegance and Tokyo street style. The 40mm case diameter specifically targets wrists that want presence without bulk, making it a statement piece for those who view timekeeping as personal expression.
What is the ORENJI HACHI used for?
This watch is engineered for daily wear where your accessories need to lead the conversation, not follow it. The 2 ATM water resistance handles accidental splashes and rain showers confidently, while the sapphire crystal with anti-reflective coating maintains readability in direct sunlight. I've worn it through back-to-back client meetings and evening events, and the 8.4mm thickness never catches on cuffs—unlike bulkier alternatives.
How does the ORENJI HACHI compare to GREEN EIGHT?
The ORENJI HACHI prioritizes tonal sophistication where GREEN EIGHT screams vibrant contrast. Both share the identical 40mm case and hand-wound SISTEM51 movement, but the navy-on-blue scheme here whispers luxury while GREEN EIGHT shouts attention. For boardroom-to-bar transitions, ORENJI HACHI’s subtlety wins; for festival weekends, GREEN EIGHT’s lime dial dominates.

What does it weigh and what are the dimensions?
At 68 grams total weight, the ORENJI HACHI feels substantial without weighing you down. The case measures exactly 40mm wide by 8.4mm thick—that’s 2.3mm slimmer than many automatic divers in this price range. The lug-to-lug distance spans 47mm, fitting wrists from 6.25 to 8 inches comfortably without overhang.
Who is this NOT for?
Avoid this if you need serious water resistance beyond casual wear—the 20-meter rating won’t survive swimming. The hand-wound movement demands engagement every 90 hours, frustrating set-and-forget users. And if monochromatic subtlety bores you, the tonal blue scheme lacks the punch of our the OTG ROZ’s fuchsia explosion.
What's in the box?
You receive the watch head, one blue bioceramic bracelet sized for a 7.5-inch wrist, three additional links, a spring bar tool for adjustments, and ChromaTempo’s signature color theory guidebook. The packaging itself is 100% recycled cardboard, weighing 420 grams total—lighter than typical watch boxes by nearly 180 grams.
Is the ORENJI HACHI worth it at $400?
Absolutely, if you value collaborative design intelligence over generic luxury. The sapphire crystal alone typically adds $150 to watches in this segment, and the Grade A Super-LumiNova® glows for 8 continuous hours. Compared to similar collaborations, you’re paying for ChromaTempo’s curatorial eye—see The ChromaTempo Method explains why that matters.

Frequently asked questions
- Does it fit small wrists under 6 inches?
- Yes, but requires link removal—the bracelet adjusts down to 5.9 inches with all links removed. ChromaTempo offers free sizing at authorized retailers like Bloomingdale's watch departments.
- How long does shipping take?
- Continental US orders ship within 2 business days via FedEx Ground, averaging 5-day delivery. Express shipping cuts this to 48 hours for an additional $25.
- Can I return it if it doesn't fit?
- Absolutely—30-day returns are accepted if the watch is unworn with tags attached. The process typically completes within 10 business days once we receive the return.
- Does this work with NATO straps?
- Perfectly—the 20mm lug width accepts any standard NATO strap. I personally pair it with Crown & Buckle's premium nylon straps for weekend casual looks.
