Glossary

Screw-down crown

The crown (or the crown of the hands, if the watch is quartz), which is fixed on a special thread during non-working hours. Accordingly, for use for its main purpose, such a head must first be unscrewed, and only then it can be rotated.
The screw design serves two main functions. Firstly, it does not allow the head to move in case of accidental contact with surrounding objects (whereas a conventional head can be hooked and rotated in case of an unsuccessful hand movement, knocking down the position of the arrows). Secondly, the head fixed on the thread plays the role of a protective cap covering the gap between the axle and the body - this improves moisture protection.

Thickness

The thickness of the watch case. A fairly obvious parameter; we only note that nowadays it is customary to attribute watches with a thickness of less than 7 mm to ultra-thin models. This design has both aesthetic and quite practical meaning — a thin watch will be useful for those who wear narrow sleeves with tight-fitting cuffs.
