The Sinn 556 I Mother-of-Pearl Black watch perfectly combines elegant design and functional engineering for fine-watch enthusiasts. It features a round stainless steel case, renowned for its strength and durability. The brushed/satin matte finish lends a distinguished look while offering everyday scratch resistance. Measuring 38.50 mm in diameter and 11.00 mm in thickness, this timepiece weighs in at 65.00 grams for a perfectly balanced feel on the wrist. A fixed steel bezel enhances its clean, modern aesthetic. A screw-down caseback ensures superior water resistance and protects the inner mechanism. For optimal legibility, the watch features a flat sapphire crystal with double anti-reflective coating, celebrated for its clarity and scratch resistance.
The dial of this watch is undoubtedly one of its most captivating features. Its mother-of-pearl finish adds depth and luxury that instantly catches the eye. The shimmering iridescence creates a truly unique dynamic, beautifully capturing the light. The dial offers a crisp analog display showing the hours, minutes, and seconds, complete with modern hands and indices coated in SuperLuminova luminescent material.
At the heart of this stunning timepiece lies a cutting-edge automatic movement powered by a Sellita SW 200-2 caliber. Operating at a frequency of 28,800 vibrations per hour (vph), or 4 Hz, it delivers impressive precision for all timekeeping displays. Offering a power reserve of up to 65 hours, it keeps running reliably even when not worn daily. An integrated hacking seconds mechanism allows for effortless, precise time-setting, further elevating the user experience.
Enhancing both comfort and style, the strap is crafted from gray Alcantara, a soft, luxurious material prized for its contemporary look and exceptional comfort. Accented with topstitching, it delivers a distinct sense of style along with lasting durability. Featuring a 20.00 mm lug width, it secures with a pin buckle that ensures a snug fit while remaining easy to adjust and remove.
Water resistance is essential in precision watchmaking, and this model delivers with a water resistance rating of 20 ATM, or up to 200 meters. This means it easily withstands everyday splashes and is fully suitable for swimming and diving.
