The Seestern S443 is more than just a chronograph; it's a tribute to traditional mechanical watchmaking, designed for those seeking a timepiece with a bold character and impeccable finishes. With a 40 mm 316L stainless steel case, this model offers a balanced and versatile feel on the wrist, made even more comfortable by a thickness of 13 mm and a lug-to-lug measurement of 48.6 mm.

Beneath the dial beats the renowned Seagull ST1901 manually wound movement. This caliber is beloved by enthusiasts for its column wheel, a complication typical of haute horlogerie that ensures smooth and precise chronograph engagement. With a frequency of 3 Hz (21,600 vibrations per hour) and a power reserve of approximately 45 hours, the S443 celebrates the daily ritual of hand-winding.

The deep black dial features a bicompax layout with a 12-hour indicator and small seconds, flanked by a 30-minute chronograph counter. Legibility is guaranteed in all lighting conditions thanks to the use of Super BGW9 on the hands and 3D indices, which emit a vivid glow in the dark. The entire dial is protected by scratch-resistant sapphire crystal, synonymous with resistance and absolute transparency.
