The Miyota 1L22 is a Japanese two-hand quartz watch caliber - hour and minute, no date - made by Miyota, the movement division of Citizen. It is a small movement of roughly 15.3 by 18.2mm with an overall height of about 3.24mm, running on a 321 type battery rated for up to 60 months. Caligio uses the Miyota 1L22 in all eight of its watches, each $99, in a 41mm solid 316L stainless steel case only 7mm thick.
The Miyota 1L22 is a Japanese two-hand quartz watch caliber made by Miyota, the movement division of Citizen. It runs the hour and minute hands only, with no date, measures roughly 15.3 by 18.2mm at about 3.24mm overall height, and takes a 321 type battery rated for up to 60 months.
Miyota 1L22 - The Short Version
- Who makes it: Miyota, the movement division of Citizen, supplying brands worldwide since the 1980s.
- What it is: a two-hand quartz caliber - hour and minute, no date, no seconds hand.
- Size: roughly 15.3 x 18.2mm, about 3.24mm overall height. Small and slim.
- Battery: a 321 type cell, rated up to 60 months. Any watchmaker stocks it.
- Why it matters: a 3.24mm movement is what allows a 7mm case.
- Where you can wear one: inside every Caligio watch, at $99.
Most watches under $100 do not tell you what is inside them. They say Japanese movement, or precision quartz, or nothing at all, and those phrases are chosen precisely because they cannot be checked. So here is the opposite: the exact caliber in every Caligio watch, what it is, who makes it, and what its numbers actually mean on your wrist.
Who Makes the Miyota 1L22
Miyota is not an independent brand that happens to sound Japanese. It is the movement division of Citizen, and it has been supplying calibers to watch companies around the world since the 1980s. Miyota movements turn up inside Citizen watches, Bulova watches, Wittnauer watches, and a great many others from brands that do not make their own - which is the ordinary state of affairs in watchmaking, since almost nobody at any price builds their own movement.
The 1L22 sits in that lineage directly. It interchanges with the Citizen 1020 and 1022, which is about as clear a statement of parentage as a caliber can make.

The One Number That Explains the Watch
Look at the height again: about 3.24mm. That is the whole reason this caliber is in a Caligio and not a thicker, less expensive alternative.
A case has to contain its movement. That is not a design philosophy, it is geometry - whatever the movement is, the watch must be taller than it, plus the dial, the crystal, the caseback, and the clearance between them. So the movement, chosen before anything else, silently sets the ceiling on how thin the finished watch can ever be.
Most watches under $100 sit somewhere between 10mm and 13mm thick, and it is not because their designers wanted them that way. It is because a thicker movement is a less expensive movement, and once it is inside, the case has no choice. The Caligio is 7mm because the 1L22 is 3.24mm. That number is not a spec-sheet detail - it is the difference between a watch that slides under a shirt cuff and one that catches on it every time you reach for something.
All eight Caligio dials run the same caliber. The face changes; the movement, the case, and the steel do not - which means the choice between them is aesthetic rather than a question of what you are getting.
Two Hands, and Why That Is a Choice
The 1L22 drives an hour hand and a minute hand. There is no date window and no seconds hand, and that is not a limitation being tolerated - a two-hand caliber suits a minimalist dial, and every element a movement does not have to drive is height it does not have to add. The clean face and the 7mm case are the same decision seen from two sides.
The Battery: Five Years, and a Cell Anyone Stocks
The 1L22 takes a 321 type battery, usually listed as a Renata 321 or an SR616SW, and that cell is rated for up to 60 months. Real life is less tidy than a rating - temperature and use both matter - so three to five years is the honest expectation. The useful part is that it is a completely standard cell: any watchmaker has one in a drawer, and it costs a few dollars. No proprietary part, no sending the watch anywhere.
On Accuracy
Quartz is the reason a $99 watch keeps better time than mechanical watches costing many multiples of it. A vibrating crystal is simply better at counting seconds than a spring driving a train of wheels, and that advantage belongs to the technology rather than to the price of the watch built around it. This is the part people find counterintuitive: on pure timekeeping, the inexpensive quartz wins, and it is not close.
What a mechanical watch offers instead is craft, a sweeping hand, and the fact that a small machine on your wrist is doing something remarkable. Those are real reasons to want one. Accuracy is not among them - and at $99, as covered in the honest teardown, a good automatic is not on the menu anyway.
Why a Named Japanese Caliber Is Rare Under $100
A named Japanese movement costs more than an unnamed one. That is the entire explanation, and everything else follows from it.
At $99, that difference has to come out of something - the case metal, the crystal, the clasp, or the margin. Most brands would rather keep it and write Japanese movement on the listing without saying which, because the phrase does the marketing work while committing to nothing. A caliber number can be looked up, cross-referenced, and held against the brand later. A vague phrase cannot, and that is precisely why so few of them get printed.
So the useful question when you are shopping under $100 is not whether the movement is good. It is whether anyone will tell you what it is.
Ask for a caliber number. The answer, or the silence, tells you everything.The Bottom Line
The Miyota 1L22 is a Japanese two-hand quartz caliber from Miyota, the movement division of Citizen, which has supplied movements to brands worldwide since the 1980s. It is roughly 15.3 by 18.2mm at about 3.24mm overall, takes a standard 321 type cell rated up to 60 months, and interchanges with the Citizen 1020 and 1022. That 3.24mm is the number that matters: because the case has to contain the movement, a slim caliber is the only way to a slim watch - and it is why the Caligio case is 7mm where most watches at this price are 10mm to 13mm. It runs in all eight Caligio dials at $99 each, in a 41mm solid 316L stainless steel case. Designed in Los Angeles since 2020, gift-boxed.
