What is a bezel and why is it important? ⌚✨ | Chrono 10:10 12 June 2025

A bezel (also called ring, rim, or lunette) is a structural element of a wristwatch that secures the crystal to the dial. It can be rotating or fixed and serves various functions.

🔁 A multifunctional breakthrough

In the 1950s, watchmakers explored the bezel’s potential to add functions without enlarging the watch.
World War II accelerated the development of technical bezels.

Bezel became:

  • 🐠 Crucial for diver’s watches (ISO 6425 standard)

  • ✈️ A navigation tool for pilot watches (logarithmic scale, GMT, etc.)

🔄 Bezel types:

  • Unidirectional ➡️ typically for divers

  • Bidirectional 🔁 for military or sport purposes

📏 Most common bezel markings:

  • Tachymeter 🏁 — to measure speed

  • Pulsometer ❤️ — to check your pulse

  • Telemeter ⚡ — to measure distance to an event (e.g., lightning)

  • Diver's 🌊 — underwater time safety

  • Yacht Timer ⛵ — countdown for regattas

  • Logarithmic 📐 — math functions for pilots (fuel, speed, etc.)

  • GMT 🌍 — tracks a second time zone

  • Compass 🧭 — sun-based orientation

🛠 Using a bezel

You can:

  • Track a second time zone 🌐

  • Use it as a timer by aligning "0" with the minute hand ⏱

⌚ How to choose a bezel watch:

  • 🎯 Know what you need it for

  • 🧱 Choose material: steel, aluminum, or ceramic

  • 👁 Check for readability of numerals and markers

The bezel is not just a design element — it’s a powerful, non-digital tool ⚙️💡
