The ratchet exists so that two people get the same reading · review
A digital micrometer over 0–25 mm (0 to 0.98 in) with a ratchet control, and the clearest example in this hub of resolution being described as accuracy.
What the figures leave us with The ratchet is the reason to buy it. The accuracy claim is the reason to read the manual rather than the listing.
The most useful feature in this hub, and its clearest specification error, on the same page.
A measuring range of 0 to 25 mm (0 to 0.98 in) with a stated accuracy of 0.001 mm — see below. A digital LCD display with switching between units. A measuring head in hard alloy steel, described as wear-resistant and rustproof for stable accuracy and long life. Operating instructions noting that a fully opened sleeve may need manual release via the ratchet control, with a warning not to force it because the fine thread can be damaged.
A thousandth of a millimeter is the step of the display. It is not what the instrument guarantees. The distinction is not academic: it is the difference between a tool that resolves fine differences and a tool that knows where zero is. Every micrometer here displays finer than it measures, and only one — the Beslands — says so.
A micrometer is a screw. Turn it harder and the number gets smaller, indefinitely, because you are compressing the part and flexing the frame. A ratchet slips at a fixed torque and removes the operator from the measurement. It is the single feature that makes a micrometer repeatable, and this is the only one in this hub whose listing describes it.
No such listing: the American Amazon shop answers the reference with a search box rather than a page.

That is the display resolution, not an accuracy. A 0–25 mm (0 to 0.98 in) micrometer accurate to a thousandth of a millimeter would be a laboratory instrument. The Beslands micrometer in this hub states its resolution as 0.001 mm and its accuracy as ± 0.003 mm — the same class of tool, described correctly.
It slips at a set torque, so the spindle always closes on the part with the same force. Without it, the reading depends on how hard the operator squeezes, and two people never agree.
Tolesum states that if the sleeve is opened fully to the stop it may need manual release, and warns against forcing it because the fine thread can be damaged. Worth knowing before it happens.

Repeatable measurements by more than one person, thanks to the ratchet.
Specifications: the manufacturer sheet for measuring instruments and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
0–25 mm (0 to 0.98 in) · 0.001 mm resolution · ± 0.003 mm accuracy · carbide tip
The only micrometer in this hub that publishes resolution and accuracy as separate figures — 0.001 mm and ± 0.003 mm — on a carbide measuring tip.
Best for: Anyone who wants to know what the instrument actually guarantees before buying it.
0–25 mm (0 to 0.98 in) · 0.001 mm resolution · hardened alloy head · CR2032
A digital micrometer over 0–25 mm (0 to 0.98 in) with a 0.001 mm display step and a hardened alloy measuring head, running on a CR2032 cell.
Best for: Somebody who wants micrometer resolution without learning to read a thimble.
0–25 mm (0 to 0.98 in) · 0.01 mm resolution · carbide faces · spindle lock
A mechanical micrometer over 0–25 mm (0 to 0.98 in) reading to 0.01 mm, with carbide measuring faces and a spindle lock, at a quarter of the price of the digital ones here.
Best for: Learning to use a micrometer, and for a workshop that wants one that never has a flat battery.
