Casio CMK-100 Automatic: The First Automatic in Casio's Core Catalog, in Titanium with a Japanese Movement

The Casio CMK-100 Automatic is a titanium-cased field watch that Casio announced on October 29, 2026, in five references. Casio's own announcement describes a lightweight titanium case, an automatic movement made in Japan and 10 bar of water resistance. Outlets report prices from $330 or €299 to $440 or €399 , with US sales reported for November 19. It is not Casio's first mechanical watch, but outlets describe it as the first automatic sold under the plain Casio name, rather than Edifice.

At a glance

What the Casio CMK-100 Automatic is

Casio's announcement of October 29, 2026 introduces the CMK-100 as a lightweight mechanical watch with strong legibility. It comes in five references: the CMK-100TD-1A on a titanium bracelet with a black dial, the CMK-100TC-1A and CMK-100TCC-8A on nylon, and the CMK-100TL-1A and CMK-100TCL-5A on leather. The TC, TL and TD have black dials, the TCC has a gray dial and the TCL a brown one.

The look is a compact field watch: three hands, a date window at 3 o'clock and large Arabic numerals. G-Central compares the styling to Sinn and Unimatic watches, which is its reading, not a Casio statement.

Case, titanium and finish

Casio says the case is titanium, with a hairline finish on the case and bezel. Gear Patrol and G-Central add that it carries a titanium carbide coating and ion plating for scratch resistance. The gray and brown versions use coated titanium, not another metal. Casio does not state the titanium grade.

Monochrome, WatchDavid and HiConsumption give the same size: 38 mm wide, 11.4 mm thick and 44.7 mm lug to lug. Weight is reported at about 54 g on leather, 55 g on nylon and 98 g on the titanium bracelet. The crystal is sapphire and the crown and caseback are screw-down, per WatchDavid and HiConsumption. Casio's announcement gave none of these figures.

Movement and specifications

Casio calls the movement a Made-in-Japan automatic and does not name the maker. WatchDavid reports that Casio's technical data lists it as module 5766. WatchDavid, HiConsumption and Gadgeteer give the same figures: 21 jewels, 21,600 vibrations per hour, about 42 hours of power reserve, hand-winding, hacking seconds and a stated daily rate of minus 20 to plus 40 seconds.

UNCERTAIN: G-Central, WatchDavid and Monochrome say the movement is probably a Miyota 8215, and Gear Patrol says it appears closely similar. No outlet reports a Casio or Citizen confirmation, so treat the Miyota attribution as an informed guess.

Only the movement is confirmed as Japanese. No source says where the case is made or the watch assembled, so a full “Made in Japan” claim is unsupported.

Casio CMK-100 price and release date

US prices, from Casio's US listing as reported by Notebookcheck, G-Central and Gadgeteer, are $330 for the black nylon TC-1A, $350 for the gray TCC-8A and the leather TL-1A, $375 for the brown TCL-5A and $440 for the TD-1A bracelet. UNCERTAIN: Gadgeteer, Gear Patrol and HiConsumption say Casio America's launch release puts the TC-1A at $320.

In Europe, Notebookcheck's Netherlands listing and WatchDavid agree on €299 for the TC-1A, €319 for the TL-1A and €399 for the bracelet; Notebookcheck also lists the TCC-8A at €319. We found no Japanese yen price.

Release timing differs by source. Gear Patrol and HiConsumption report US sales from November 19, 2026. WatchDavid reports Europe from November 12, 2026. Notebookcheck noted the US store first tagged them as October releases.

What “first automatic” means

The claim needs care. Casio's first mechanical watch was the Edifice EFK-100, reported by Monochrome on July 15, 2025. It was a 39 mm steel watch with a Seiko NH35 movement, priced at €279 or $280 in steel. Casio's Edifice EFK-110 followed in Europe on March 18, 2026, at €279, per Casio's European release, which says it uses a Japanese movement.

So the CMK-100 is not Casio's first automatic. Gear Patrol calls it the first in Casio's core catalog, meaning neither Edifice nor G-Shock, and HiConsumption calls it the first automatic under the plain Casio name. We found no source naming an earlier Casio automatic, but that is an absence of evidence, not proof that none exists.

Where the CMK-100 sits

We did not verify prices of rival titanium automatics, so no head-to-head is offered. Within Casio's range, the entry CMK-100 at $330 or €299 sits close to the steel Edifice EFK-100 at $280 or €279. Our guides to the best watches under $500 and under $1,000 cover the wider market.

Interpretation. Titanium, sapphire and a Japanese movement at this price suggest Casio is moving mechanical watches from a sub-line into its main catalog. Whether more automatics follow is unknown, and Casio has not said so.

CMK-100 references, prices and availability

Background

Casio's first watch was the Casiotron QW-02 of 1974, per Monochrome, and the brand grew in the quartz revolution and the quartz crisis, told in our Casio history. Cheap digital watches such as the F-91W, the G-Shock and the octagonal GA-2100 followed.
