In a market full of overpriced quartz watches and overcomplicated smartwatches, the Tissot PRC 100 Solar stands out as a beautifully balanced, solar-powered Swiss timepiece that looks just as sharp at the office as it does on a weekend hike. But is it just another good-looking watch—or is it actually the best solar quartz watch under $500?

If you’re searching for a durable, accurate, and low-maintenance timepiece, this might be your ideal match.

Whether you’re deep into the watch enthusiast world on Reddit or just dipping your toes into quality Swiss watches, the PRC 100 Solar deserves your attention.

What is the PRC 100 Solar?

The Tissot PRC 100 Solar is a solar-powered quartz watch produced by the iconic Swiss brand Tissot, which has been around since 1853. Unlike traditional battery-powered quartz watches, this model uses solar charging technology to stay powered through any light source—natural or artificial. With a 100-meter water resistance, stainless steel case, sapphire crystal, and a reliable movement, this watch blends sport and elegance in one slim package.

The “PRC” in its name stands for Precise, Robust, Classic, and it delivers on all three.

PRC 100 Solar Watch Features

The standout feature of the PRC 100 Solar is, of course, its solar quartz movement—a rarity in Swiss watches at this price point. But there’s more to this timepiece than just its green credentials.

🧠 Core Features Include:

• Solar-powered quartz movement: No battery changes required
• Stainless steel case: Available in 34mm or 39mm sizes
• 100m water resistance: Swim and shower-friendly
• Anti-reflective sapphire crystal: Scratch-resistant and ultra-clear
• Date display at 3 o’clock
• Luminous hands and indices for low-light readability
• Available dial options: Includes the popular PRC 100 Solar black variant
• Swiss Made: Built to precise, heritage standards

The case is polished and slightly sporty, with chronograph-inspired details and bold hour markers. It’s not a dive watch, but it holds up to active, everyday use exceptionally well.

Available Sizes: 34mm vs. 39mm

Tissot offers two key case sizes for the PRC 100 Solar: 34mm and 39mm. This makes it an excellent unisex option depending on your wrist size and style preferences.

• PRC 100 Solar 34mm – Ideal for smaller wrists, women, or those who prefer a minimalist presence
• PRC 100 Solar 39mm – A perfect mid-size daily wear, especially for men or those who want more dial real estate

Both retain the same solar-powered movement and core feature set, giving you choice without compromise.
