Strehler, the new luxury watch brand founded by world-renowned Swiss independent watchmaker Andreas Strehler, presents its debut creation, Sirna.
This model is named after Sirnach, the home of Andreas Strehler’s horology atelier. With the new brand, the watchmaker shares his passion for high-end watchmaking with a broader audience by offering more widely available creations.
Entirely crafted in the master watchmaker’s own workshop in Sirnach, Strehler Sirna encapsulates the creator’s philosophy, watchmaking expertise and exquisite craftsmanship into a simple daily watch.
The entire watch, from the movement to the case, dial and hands, is in-house produced by a dedicated team. 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 manufacture in the German-speaking part of Switzerland.
The Sirna houses the calibre SA-30, a brand new automatic movement entirely developed, manufactured and finished in-house.
A superb, robust and reliable engine, the Calibre SA-30 is regulated by a Swiss lever escapement special to Strehler and a large free-sprung balance wheel. Its large barrel delivers a particularly constant torque and ensures 60 hours of power reserve.
Visible via the exhibition caseback, the impeccable execution of the finishings –chamfered and polished bevels, circular Geneva stripes, graining or circular-grained wheels– all channel the movement’s sophisticated architecture. The bridges and the skeletonised 18k gold rotor create a series of circles that echo the curvature of the case.
With its versatile 40mm diameter and harmonious proportions, the elegant polished steel case feels quintessentially “Strehler”. The elongated lugs beautifully extend the case band and gently bend downward for enhanced ergonomics.
With its concave profile, the Sirna is particularly thin (8.5mm) which offers superb comfort on the wrist, making for a great daily wearer. The classic case, case back and bezel construction is water-resistant to 3 atm.
The compelling dial is crafted from titanium and features a small second’s counter at 6 o’clock, offering a perfectly balanced layout. The dial together with the unique three-dimensional pattern has been created with renowned watch designer Eric Giroud. Achieved by anodization, the intense blue colour of the titanium will not fade overtime. Together with two applied stainless steel chapter rings, it produces a captivating sense of depth.
Also manufactured in-house and shaped in characteristic “Strehler” style, the steel hands are delicately hand-polished. The stainless-steel crown bears a blue titanium insert.
The watch comes with an elegant and supple brown calfskin leather strap with off-white stitching. It is secured to the wrist by an in-house made steel pin buckle whose profile echoes that of the case.
Beautifully presented in a beech wood box, the Strehler Sirna is accompanied by a cognac leather travel pouch.
Although it is not a limited edition, production of the watch is naturally limited by the artisanal manufacturing methods involved. The production is limited to approximately 30 to 50 watches per year.
