Quick TakeThe Sinn 456 St I is a little titan. Don't let the dainty 28mm case fool you; this watch packs the robust engineering Sinn is known for into a seriously elegant package. It's a marvel of purposeful design, sporting a high-contrast black dial with luminous hands and appliqués, all shielded by scratch-resistant sapphire. Flip it over, and the exhibition case back reveals the precise ticking heart – the SW 100 automatic movement. With its 20-bar water resistance, anti-magnetic properties, and overall steadfast construction, this isn't just a pretty face. It's built for life's everyday adventures, and looks gorgeous at your next dinner. The 456 is a paradox in the best way: it's tough and ready, yet impeccably refined. A watch that really does check all the boxes. The seconds stop function allows one to perfectly, and easily, set the time, while 26 jewels ensures accuracy and a long life for the caliber.

DescriptionThe Sinn 456 St I, reference 456.010, represents a deliberate engineering exercise in crafting a robust yet elegant timepiece for women. The watch's construction centers around a compact, polished stainless steel case measuring 28mm in diameter and 9mm in thickness. This case, designed to meet the technical requirements for water resistance as defined by DIN 8310 standards, achieves a pressure resistance of 20 bar, rendering it suitable for swimming and diving activities. Further enhancing its resilience, the case is also resistant to low-pressure environments. The design adheres to anti-magnetic standards specified in DIN 8309, protecting the movement from the disruptive effects of magnetic fields. A screw-fastened case back secures the internal components. The front crystal is fabricated from sapphire, treated with an anti-reflective coating on both sides to minimize glare and maximize legibility under various lighting conditions. The exhibition case back is also crafted from sapphire crystal with an interior anti-reflective treatment, providing a visual insight into the automatic movement.

Powering the 456 St I is the SW 100 self-winding mechanical movement. This caliber features 26 bearing jewels, contributing to its accuracy and longevity. The movement oscillates at a frequency of 28,800 semi-oscillations per hour, resulting in a smooth sweep of the seconds hand. Furthermore, it features a seconds stop function, allowing for precise time setting, where the second hand will cease operation when the crown is fully pulled out. The dial, electroplated in black, maintains a minimalist aesthetic, enhancing readability. The hours, minutes and seconds hands, along with select appliques, feature luminescent colour. Hand-applied appliqués provide dimensional detail. A date display is positioned at the 6 o'clock location. The design ensures legibility. The stated specifications pertaining to the mechanical movement reflect current production standards, and are subject to minor change due to continual manufacturing developments. The watch itself, without a strap, weighs 30 grams. The width of the band lugs are 14mm.
