The core trade-off is scratch resistance versus shatter resistance. Sapphire is very hard to scratch but can chip or crack from a sharp impact on an edge. Acrylic scratches easily but flexes, rarely shatters, and light scratches can be polished out at home. Mineral glass sits in between and is often the cheapest to replace.

Jewel count describes bearings used in a movement design; it is not a quality ranking. Compare the documented movement architecture and service support rather than assuming a higher count makes one watch better.

Case 18 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Clarifying question: what does daily wear mean for you? Desk work, manual labour or sports change the answer. For desk use, sapphire's scratch resistance is the main benefit.
