Oris Aquis Date Calibre 400 Stainless Steel Blue Dial Automatic Watch 43.5mm

Quartz: Battery-powered and highly accurate, quartz movements offer ±10 seconds per year precision thanks to technologies like PreciDrive and HeavyDrive. Mechanical: Requires manual winding; powered by a mainspring and gear train. Known for craftsmanship, but less accurate than quartz. Automatic (self-winding): A type of mechanical movement that winds via wrist motion—combines luxury tradition with hands-free convenience.

High-tech ceramic bezels are ultra-hard, scratch-resistant, lightweight, and often hypoallergenic—ideal for daily wear and retaining their pristine look over time. Paired with stainless steel, they enhance both durability and luxury appeal.

Sapphire crystal is a durable, scratch-resistant material used for watch faces. Anti-reflective coatings, especially on the inner side, significantly improve clarity and legibility in bright lighting conditions.

Complications are additional functions beyond telling the time. Common ones include chronographs (stopwatch features), dual time zones, perpetual calendars, and moon phase indicators—that showcase expert craftsmanship and enhance a watch’s functionality.

Water resistance is rated in meters or ATM (atmospheres): 30m/3 ATM – can handle splashes only 100m/10 ATM – suitable for swimming Tests are performed under static conditions—avoid relying on them for diving or high-pressure water sports.

A chronometer is a watch officially certified (e.g., by COSC) for exceptional accuracy. It’s not a complication like a chronograph—rather, it’s a mark of precision and quality.

A skeleton watch features a fully hollowed-out movement—artfully exposing gears and components. An open-heart watch reveals just a portion of the movement, allowing you to glimpse the mechanics with a more subtle aesthetic.

Yes—exposure to magnets can cause them to run fast or slow, affecting accuracy. Some movements today are built with antimagnetic materials like Nivachron™ hairsprings to enhance precision and resilience.

Premium timepieces often use stainless steel, titanium, gold, platinum, ceramic, and sapphire crystal. These materials contribute to both durability and refined aesthetics, depending on the watch’s intended purpose and design.

Mechanical and automatic watches typically require servicing every 3–5 years to keep them accurate and prolong their lifespan. Service includes lubrication, calibration, and water resistance testing.
