The Sirna is the first timepiece of the new brand STREHLER. A three-hand automatic watch for everyday wear as well as for any formal occasion, made entirely in-house in our workshop in Sirnach.
Focusing on the essential, the Sirna has a 40mm stainless steel watch case, made from medical grade steel. And in house of course. With a height of only 8.5mm, it fits perfectly on any wrist. The concave profile that blends elegantly into the lugs makes the watch look more delicate. The Sirna case thus pays homage to Andreas Strehler’s complex Cocon watch case. However, with its harmonious proportions, the polished steel case is quintessentially “STREHLER” and an elegant design in its own right: The fluid lines and the elongated lugs add a distinctly modern touch and beautifully extend the case band. These lugs, gently bending downwards, enhance ergonomics on small wrists and look equally good on more solid ones. With its concave profile, the Sirna offers superb comfort on the wrist, making it a great daily wearer. The classic case – case back – bezel construction is water-resistant to 3 atm.
STREHLER focuses on the essentials, maintaining an uncompromising manufacturing ethos. With its creator’s philosophy, our watchmaking expertise and the exquisite craftsmanship applied, the Sirna is designed to stand the test of time – a watch for many generations to come.
The entire watch, from the movement to the case, dial and hands, is produced by a dedicated team in the brand’s own workshop. Based in Sirnach, a small town of the canton of Thurgau in between lake Constance and the alps, it is one of the very few full-fledged watches manufactured in the German-speaking part of Switzerland.
