Sub-$400 finally gets a serious diver. Orient’s new AC0Q Diver II lands at $370 right now: sapphire crystal, 200m rating, 39.9mm case, no asterisks. That’s roughly 30% under the $530 MSRP, and the two limited editions sit at $395 (about 25% off) for the same package in smokier dial colors.

The watch carries two names. Orient’s global marketing calls the lineup the “Diver Design 40 Series.” Orient Watch USA calls it the AC0Q Diver II. Same five watches, two storefronts, one compact case that traces back to Orient’s 2023 sub-40mm refresh, the one watch press kept calling the Mako 40 even though Orient itself uses just “Mako” in its own marketing, never “Mako 40.” What’s new sits on the dial, and it’s worth a closer look.
The five models, priced
Five references, all 39.9mm, all stainless steel bracelets. The standard trio runs green (RA-AC0Q13E30B), blue (RA-AC0Q14L30B), and brown (RA-AC0Q15Y30B) at $370 during the launch promo. List on each is $530. Solid pricing for a sapphire 200m diver at this size, even before you factor in the launch discount.
Then come the two limited editions: grey (RA-AC0Q16N30B) and brown (RA-AC0Q17Y30B), priced at $395 with a $25 walk-up over the standards. Dial finishes are where the money goes. Orient’s global press release describes the LE pair as “stylish grey” and “warm copper,” the latter being what Orient Watch USA labels simply as “brown” on its product page (worth noting if you’re cross-shopping between the global and US storefronts). Orient hasn’t published a production count for either LE, which is the usual signal that a number exists and someone decided not to share it.
Worth flagging the label on every product page. “Exclusive Website Offer.”
That phrase sounds time-limited. It isn’t. Orient Watch USA has been running the same MSRP-to-promo structure on the Kamasu, the Ray II, and the AA02 for years now, with the “discounted” prices acting as de facto retail. Treat the $370 and $395 numbers as what you actually pay, not a clock running down on you.
What Orient changed from the original AC0Q
Almost nothing on the case. The original RA-AC0Q line, Orient’s 2023 sub-40mm sports refresh, set the template, and the Diver II keeps every dimension intact: 39.9mm wide, 46.5mm lug-to-lug, 12.8mm thick. Same caliber, same sapphire, same 200m rating, same 20mm lugs. Flip a Diver II and a 2023 AC0Q face-down on a table, and you can’t tell them apart.
Dial work carried the project. Orient Watch USA’s product pages call the new finishes “sleek color gradients”; the global press release goes more technical, describing a “sunburst finish that creates subtle shifts in colour depending on the angle of light” applied across all five dials, with a “circular gradation that transitions from light in the centre to dark on the outer edges.” Standards run green, navy-blue, and brown; the two LEs are stylish grey and warm copper. Per Orient’s own release every reference shares the same sunburst-plus-gradation treatment, with color choice doing the differentiation.
Here’s what jumps out when you put the dials side by side. The architecture itself, meaning the handset shape, the applied indices, and the overall layout, borrows from the Kamasu rather than starting clean. That’s not a complaint. Putting the Kamasu’s hands and markers on a 39.9mm case is the kind of move that works precisely because the donor was already strong.
Orient AC0Q Diver II specs
Under the dial sits Orient’s Caliber F6722, an Epson-manufactured automatic (Orient has been owned by Seiko Epson since 2009, in case the lineage matters to you). You get hand-winding, hacking, and approximately 40 hours of reserve: real mid-tier numbers at this price, no inflated marketing claims. Case is 39.9mm wide, 46.5mm lug-to-lug, 12.8mm thick, in stainless steel with a screw-down crown, sapphire crystal, and a 120-click unidirectional stainless bezel.
Bracelet’s stainless with a foldover clasp and safety. 20mm lug width if you want to strap-swap. Warranty’s the standard two-year Orient Watch USA package. Date complication only, on every reference including both limited editions, which means Orient didn’t slip in a day-date variant to upcharge the LE buyers: a small consumer-respect detail that’s easy to miss.
Orient AC0Q Diver II vs Kamasu and Ray II
Size is the whole conversation here. The Kamasu measures 41.8mm wide. The Ray II / AA02 runs 41.5mm. Both wear bigger than the AC0Q Diver II’s 39.9mm in a way you feel under a button cuff, not only on a calipers reading.
Price ladders down, not up. The AC0Q Diver II’s $530 MSRP undercuts the Kamasu’s $580, which is unusual for what you’d expect to be Orient’s “premium compact” reference. You’re paying less for the smaller case, the sapphire crystal, and the same 200m rating: a pricing inversion that only makes sense once you accept the Kamasu’s larger case demands more steel and a different movement (Orient’s F6922 instead of the F6722).
The pitch writes itself. If the Kamasu felt too big on your wrist and you couldn’t justify dropping to the Ray II’s lower spec sheet, this is the watch you’ve been waiting on. Tied with the original 2023 AC0Q Mako 40 at 39.9mm for the most compact 200m diver in Orient’s current US catalog.
Price and availability
Available now at orientwatchusa.com. Standards run $370 during the launch promo (off $530 MSRP), and the two LEs run $395 off the same MSRP. All five SKUs ship with Orient Watch USA’s two-year warranty, US-only fulfillment.
International rollout hasn’t been announced, which is consistent with how Orient typically staggers regional launches. If you’re outside the US and the watch interests you, sit tight or work through a US-based forwarder. We’ll update once Orient’s regional sites pick up the lineup.
Who should buy the Orient AC0Q Diver II
You’ve got a 6.5- to 7.25-inch wrist and the Kamasu felt like wearing a hockey puck. That’s the primary audience here, and it’s a real one. Watch forums have been asking for a sub-40mm Kamasu-spec diver from Orient for years, and the Diver II answers the brief without making you compromise on water resistance or crystal material.
Spec sheet does the heavy lifting. Screw-down crown, 120-click unidirectional bezel, 200m water resistance, sapphire on top: tool-watch credentials of Orient’s larger ISO-style divers, only packaged smaller. You’re not buying down to get the size.
Skip it if you wanted the Kamasu’s dial in its original case. The Diver II runs the Kamasu’s dial layout on the AC0Q’s smaller bezel proportions, which means indices and handset sit slightly differently against the chapter ring. Most people won’t notice. Some will.
One caveat for the budget end of the conversation. If you want broad Orient diver feel and don’t care about sapphire, the Ray II / AA02 sits below this watch on price and may still be the better entry point. Not the better watch, but the better starting point.
Bottom line
Strong watch at a strong price. The AC0Q Diver II is one of the best sub-$400 dive watches you can buy right now: 39.9mm, sapphire, 200m, Orient’s F6722, and a Kamasu-derived dial on a compact case.
Price: $370 (Special Promo Price from $530)
Where to Buy: Orient
Go in clear-eyed. The case is the 2023 AC0Q’s. The dial is the Kamasu’s. The $370 launch price is Orient Watch USA’s permanent catalog structure, not a countdown.
