1. Case
The outer shell that protects the watch movement. Cases come in materials like stainless steel, titanium, or ceramic.
2. Dial
The face of the watch, where the hands and markers are displayed. Often called the “watch face.”
3. Bezel
The ring that surrounds the dial. Some are decorative, while others (like on diving watches) rotate to measure elapsed time.
4. Crown
The small knob on the side of the watch used to set the time and date — and in some watches, to wind the movement.
5. Crystal
The transparent cover over the dial. Common types include mineral glass, acrylic, and scratch-resistant sapphire.
6. Lugs
The extensions on the case where the strap or bracelet is attached.
7. Movement (Caliber)
The engine that powers the watch. The three main types are Quartz, Mechanical, and Automatic.
8. Complication
Any feature beyond basic timekeeping, such as a date display, chronograph, or moon phase.
9. Chronograph
A watch with a built-in stopwatch function, often with extra sub-dials.
10. Water Resistance
Indicates how much water pressure the watch can withstand, usually measured in BAR, ATM, or meters.
11. GMT
A function that allows the watch to display two different time zones at once.
12. Skeleton
A style where parts of the movement are visible through the dial or case back, showcasing the craftsmanship.
13. Tourbillon
A luxury complication that improves accuracy by counteracting gravity — often found in high-end watches.
14. Strap vs. Bracelet
- Strap → Leather, rubber, or fabric band.
- Bracelet → Metal link band.
15. Power Reserve
How long a watch will run once fully wound (common in mechanical and automatic watches).
