Description

The present reference is the STREHLER Sirna, the inaugural timepiece from the STREHLER brand, conceived as an integrated, three-hand automatic wristwatch for both daily wear and formal occasions. Produced entirely in-house in Sirnach, Switzerland, the watch reflects an uncompromising approach to German-Swiss artisanal manufacturing, where every element—from movement and case to dial and hands—is realized under one roof.

The watch is presented in a 40 mm case of medical-grade stainless steel, measuring a slender 8.5 mm in total height. Its architecture draws inspiration from Andreas Strehler’s complex Cocon case, distinguished by concave flanks that sweep seamlessly into elongated, downward-curving lugs. This sculptural profile reduces visual mass and enhances wrist ergonomics across varying wrist sizes. The three-piece case construction is finished with polished surfaces, fitted with sapphire crystals on both the front and exhibition caseback featuring anti-reflective coating on both sides, and rated water-resistant to 3 ATM (30 metres).

Dial-side, the Sirna prioritizes visual purity and balance, displaying central hours and minutes accompanied by a recessed small seconds sub-dial at 6 o’clock. The restrained display places full emphasis on clean legibility and proportion, designed to endure across generations without unnecessary embellishment.

Powering the timepiece is the manufacture in-house Calibre SA-30, a self-winding mechanical movement conceived and assembled by the manufacture’s dedicated team in Sirnach. Combining refined mechanical architecture with contemporary winding efficiency, it brings high-horology engineering to a versatile, three-hand format.

The timepiece is completed by a leather strap, secured by a stainless steel buckle. Standing as the foundational reference of the STREHLER brand, the Sirna captures the mastery of independent Saxon-Swiss horology in a pure, wearable everyday design.

Andreas Strehler – Bio

Swiss watchmaker Andreas Strehler trained at the watchmaking school in Solothurn before joining Renaud & Papi, where he worked as a prototype-maker on complicated movements. In 1995, he established his own workshop in Winterthur, combining restoration, movement engineering, and the creation of watches under his name. His inventive designs include the Zwei, Papillon, Cocon, and Time Shadow, often concealing sophisticated mechanisms beneath restrained, legible displays. Strehler also developed movements for established brands, including H. Moser & Cie. In 2005, he founded UhrTeil AG for engineering and production. His achievements include the 2013 Prix Gaïa and a record-setting perpetual moon-phase mechanism.
