Watch Dictionary: 10 Essential Watch Terms You Should Know

Stepping into the refined world of watches, are you often confused by the plethora of styles and descriptive professional watch terms? Understanding these terms is key to not only selecting your ideal timepiece more accurately but also to appreciating its design value and craftsmanship. For Aiers, which focuses on vintage and classic style, each term is connected to our philosophy of aesthetics and functionality. This essential watch knowledge guide will decode 10 core terms, empowering you to make informed choices and appreciate timepieces with confidence.

1. Dial

The dial is the “face” of the watch, bearing the time display and core design language. Beyond common markers and hands, the minimalist dials favored by Aiers often feature “railroad” or “grain” textures, paying homage to classical aesthetics.

2. Case

The case defines the overall texture and durability of a watch. 316L Stainless Steel is the mainstream choice for modern watches due to its excellent corrosion resistance and luster, serving as the foundation for many Aiers pieces, ensuring classic designs stand the test of time.

3. Movement

The movement is the “heart” of the watch. It is categorized into mechanical movements (requiring manual or automatic winding) and quartz movements (powered by a battery). Mechanical movements carry the romance of traditional watchmaking, while high-precision quartz movements offer exceptional convenience and reliability.

4. Sapphire Crystal

This is the transparent cover over the dial. Sapphire crystal is extremely hard, second only to diamond, making it nearly scratch-proof—a hallmark of high-quality timepieces.

5. Water Resistance

Usually indicated in “ATM” or “meters.” It’s important to note that 30-meter water resistance only protects against daily splashes, not swimming. If your lifestyle involves water activities, pay close attention to this specification.

6. Strap

The strap greatly influences comfort and style. The Milanaise strap, with its unique metal weave texture and smooth, conforming fit, is a perfect blend of vintage and modern style.

7. Lugs

The protruding parts on either side of the case used to attach the strap. The width, length, and shape of the lugs directly affect how the watch fits the strap and its overall wear profile. Aiers designs often focus on smooth lug lines to ensure a perfect match with various strap styles.

8. Luminescence

Refers to the property of hands and markers emitting a faint glow in the dark. Traditional luminous materials once used radioactive substances, while modern watches commonly employ safe, long-lasting coatings like Super-LumiNova, balancing practicality and vintage appeal.

9. Frequency

For mechanical movements, this refers to the number of oscillations of the balance wheel per hour, measured in vph (vibrations per hour). A higher frequency generally indicates higher timekeeping accuracy and resistance to interference, a key indicator of movement quality.

10. Power Reserve

Indicates how long an automatic mechanical watch can run after being fully wound. Often displayed on a separate sub-dial, this has become a complication showcasing craftsmanship, symbolizing the continuity of energy.
