Seagull's ST17 Movement

The ST17 movement, equipped with 20 ruby jewels and vibrating at a steady frequency of 21,600 vph (3Hz), serves as the foundational caliber in this collection, renowned for its classical elegance in the native "small seconds" layout. In high-end horology, this dedicated sub-dial architecture eliminates unnecessary transmission modules, ensuring a perfectly balanced layout and an ultra-low profile.

Honoring the visual geometry of classic vintage pocket watches, this automatic caliber boasts a resilient 40-hour power reserve. It features highly dependable anti-shock performance, a tightly compact ~5 mm structural build, and refined industrial finishing work. As a fully mature base movement, it seamlessly blends retro geometric charm with stable, time-tested daily accuracy, making it the perfect mechanical anchor for an enduring, minimalist timepiece with a 10 mm slim profile.
