Wristwatch Dictionary: A-Z Guide to Watch Terms

By Freddie Palmgren

Published on Oct 23, 2025 Updated on Mar 30, 2026

This comprehensive wristwatch dictionary is your fast, reliable reference for decoding the language of horology. From case anatomy and crystals to movements, escapements, and complications, each definition is concise and accurate, written to help you read spec sheets and reviews with confidence. You will also find essential standards around water resistance, anti-magnetism, accuracy, and finishing so you can compare watches on more than just looks.

Beyond the technical terms, we cover real-world ownership: buying and distribution terms, smart and connected features, packaging and carry, and the forum slang you keep seeing in comment threads. To round it out, there is an A-Z of 40 foundational brands, each with a short profile and its most iconic models.

40 Iconic Watch Brands: A-Z

This section covers 40 foundational watch brands in alphabetical order. Each entry gives a short profile and its most iconic models. This is not a ranking - it is a reference.

A. Lange and Söhne

A. Lange and Söhne revives Saxon high watchmaking with sculptural movements and exceptional hand-finishing. The Lange 1's asymmetric dial and oversized date became an instant classic at its 1994 relaunch. The Datograph redefined modern chronographs. Three-quarter plates and hand-engraved balance cocks are house signatures. Design is sober, technical, and deeply crafted.

Iconic models: Lange 1, Datograph, Zeitwerk.

Audemars Piguet

Audemars Piguet fused haute watchmaking with audacious design through the Royal Oak. Its octagonal bezel and integrated bracelet, designed by Gérald Genta in 1972, reframed luxury steel watchmaking permanently. The Offshore amplified scale and attitude. AP also excels in skeletonization and high complications.

Frequently Asked Questions

What is the difference between a complication and a function?

In horology, a complication is any feature beyond simple hours, minutes, and seconds display. A date window is a complication. A chronograph is a complication. A tourbillon is a complication. The word does not imply difficulty of use - it refers to the mechanical addition required to produce the function.

What does COSC certified mean?

COSC stands for Contrôle Officiel Suisse des Chronomètres - the Swiss Official Chronometer Testing Institute. A COSC-certified movement has been tested over 16 days in five positions and two temperatures, meeting a daily rate of -4 to +6 seconds. A watch carrying COSC certification can legally be called a chronometer.

What is the difference between sapphire crystal and mineral glass?

Sapphire crystal is synthetic corundum, rated 9 on the Mohs hardness scale. It is significantly more scratch-resistant than mineral glass and is used on most watches above the entry level. Mineral glass is tempered silica glass, rated around 5-6 on the Mohs scale - it scratches more easily but is cheaper to produce and slightly more shatter-resistant than sapphire.

What does ATM mean for water resistance?

ATM stands for atmospheres - a unit of pressure. One ATM equals approximately 10 metres of static water depth. A watch rated 3 ATM can withstand splashes. 5 ATM covers hand washing and rain. 10 ATM covers swimming. 20 ATM and above covers snorkelling and diving. Note that dynamic pressure from movement in water means real-world ratings are lower than the static test figures suggest.

What is a manufacture movement?

A manufacture movement is one designed and produced in-house by the watch brand rather than purchased from an external movement supplier like ETA or Sellita. In-house movements are generally considered more prestigious and allow the brand full control over design, specifications, and production. Not all in-house movements are better than third-party movements - quality varies significantly.

What is the difference between a chronograph and a chronometer?

A chronograph is a watch with a built-in stopwatch function - start, stop, and reset. A chronometer is a watch whose movement has been independently certified for accuracy, most commonly by COSC. The terms are frequently confused. A watch can be a chronograph without being a chronometer, a chronometer without a chronograph function, or both.

What does PVD coating mean on a watch?

PVD stands for Physical Vapour Deposition - a vacuum process that applies a very thin, very hard metallic coating to a case. It is used to create gold, black, rose gold, and other coloured finishes on stainless steel cases. PVD coatings are harder than traditional gold plating and more durable in daily wear. For more detail, see our guide to PVD gold coating on watches.
