Quick TakeThis Sinn 456.025 is more than a mere time-telling gadget; it is wearable artistry. The mother-of-pearl dial dances with light, each glance revealing a different shimmer, framed exquisitely by that 18-carat yellow gold ring. It feels classic, a throwback, but with modern bones—the robust SW 100 movement ticking away inside, viewed via the exhibition case back, is a testament to contemporary watchmaking. That 28mm case might seem dainty, but it packs technical prowess: 20-bar water resistance and antimagnetic properties keep it performing despite what is thrown at it. It is secured by a clean, white leather strap. The date window is practical, yet elegantly incorporated. She’s graceful on the wrist, whispers luxury rather than shouting it. A touch of timeless class with robust, modern mechanics, it's a piece that makes every moment feel special.

DescriptionThe Sinn 456.025, with a case diameter of 28 mm and a band lug width of 14 mm, represents a study in refined engineering. Its construction integrates a polished stainless steel case, complemented by a decorative ring meticulously fashioned from 18-carat yellow gold, also polished to a high sheen. The case, designed to meet the technical specifications for water resistance defined in DIN 8310, is capable of withstanding pressures up to 20 bar, and is certified as low-pressure resistant. The total weight, exclusive of the strap, comes to 32 grams. The screw-fastened case back, along with the front crystal, is made from sapphire crystal glass, presenting superior scratch resistance. The front crystal enjoys anti-reflective treatment on both surfaces, while the transparent case back is anti-reflective on its interior face, giving a transparent view of the movement.

Powering the 456.025 is the SW 100 self-winding mechanical movement. This caliber incorporates 25 bearing jewels to reduce friction and wear among moving parts, ensuring operational longevity. It oscillates at a frequency of 28,800 semi-oscillations per hour, providing a balance between precision and power reserve. The movement comes equipped with a seconds stop function, enabling precise time setting. This movement maintains operational integrity in magnetic environments, fulfilling the anti-magnetic criteria stipulated by DIN 8309. The display functions include central hours, minutes, and seconds hands, plus a date display. A dial fashioned out of mother-of-pearl forms the backdrop, onto which appliqués have been manually attached, adding visual complexity to the watch. The installed strap is white cowhide leather with embossed alligator print.
