Casio's anticipated titanium CMK-100 automatics leak again with two-month release window

A fresh leak has put more detail on Casio's CMK-100, the automatic series that surfaced last month. The main claim is that it will be Casio's first mechanical watch outside the Edifice line. Instagram account @geesgshock posted the three references in what looks like a promo image on Saturday: CMK-100TC-1A on textile, CMK-100TD-1A on a bracelet, and CMK-100TL-1A on leather.
The build is titanium with a sapphire crystal and a mineral glass caseback. Casio already does that on the Edifice EFK-110D, which has a sapphire front with a mineral exhibition window.
At the heart of the watch is the Miyota 8215, running 21 jewels at 21,600 vph with a 42-hour reserve. The new detail is hacking, so the seconds hand stops when the crown is pulled. Miyota only began fitting the 8215 with a stop-seconds device around 2018, so that makes sense for current production. What comes with it is the 8215's stuttering seconds hand. That's a quirk of its indirect centre-seconds drive that most will notice straight away.
Pricing is put at roughly $300; a release is expected inside two months. Casioblog, which broke the leak on 16 September, had it at $280 to $300 and would only say "the coming months", so the window has somewhat tightened. For reference, the CMK prefix is new, and no existing Casio line uses it.
Dimensions are still missing, and that is the number most people will want. Most fans on the post are guessing 39 to 40 mm. The EFK-100 was 39 mm in steel, for whatever that is worth as a reference point.
