Military watches have long been prized for their ruggedness, legibility, and mechanical reliability. If you're considering a military watch, especially an automatic one, you might be curious about how it differs from quartz watches and what features truly matter.
In this guide, we'll break down the key differences between military and quartz watches, explain why military watches emphasize legibility, shock resistance, and water resistance, and recommend several affordable and practical models.
What Is an Automatic Military Watch? And How Is It Different from Quartz?
Military watches were originally designed for soldiers in the field — intended to withstand harsh conditions while being easy to read and maintain.
The concept dates back to World War I, when pocket watches proved impractical in combat, leading to the creation of the first wrist-worn military watches such as the 1916 Girard-Perregaux models for the German Navy.
By World War II, iconic field watch designs like the A-11 (produced by Bulova, Elgin, and Waltham for the U.S. military) and the Dirty Dozen (12 Swiss brands commissioned by the British Ministry of Defence) set the standard for what we now consider the classic “military watch look”:
Today, military watches have moved from the battlefield to everyday life, becoming favorites among collectors and outdoor enthusiasts.
But a common question remains: Should you choose an automatic military watch or a quartz watch？
Automatic vs Quartz Military Watches: Key Difference
If you enjoy the feeling of a mechanical movement on your wrist and want a watch with a soul, then an automatic military watch is your ideal choice. If you just want a convenient timekeeping tool, then choose a quartz watch.
What specifications should I look for when choosing a military watch?
1. Readable Dial
A military watch must be easy to read in all conditions. Look for clear hour markers, 24-hour scale, and strong lume (glow-in-the-dark coating).
2. Durable Case
A stainless steel case (preferably 316L) is the standard. Anything that’s not plastic or zinc alloy is a good start.
3. Sapphire Crystal
It’s not always found in watches under $200, but sapphire glass resists scratches much better than mineral glass.
4. Water Resistance
At least 50M (ideally 100M), so you don’t need to worry when it rains — or when you forget to take your watch off before showering.
5. Automatic Movement
No batteries, no charging — just reliable timekeeping powered by your wrist. For many users, this adds charm, simplicity, and longevity.
