Sinn 144 St Sa (Ref. 144.020) – Classic pilot’s chronograph with robust technology
Housing and design
The Sinn 144 St Sa is presented in a satin-finished stainless steel case with a diameter of 41 mm – a classic chronograph with aviator DNA and technical charisma. The case construction with screw-down back (without viewing window) is pressure-resistant up to 20 bar and underlines the functional robustness of this watch. The dial is clearly structured, deep black and offers the best readability thanks to its high-contrast, white-printed scales and totalizers – even at glance. The tachymeter scale on the flange adds a sporty-technical component to the design. Scratch-resistant, double-sided anti-reflective sapphire crystal reliably protects the dial.
Movement and technology
Inside is the Concepto C99001 automatic movement, a modern chronograph caliber with reliable rate stability and precise function. It beats at 28,800 vibrations per hour, has 25 jewels and offers a power reserve of approximately 48 hours. The chronograph measures time intervals via central stop seconds, 30-minute and 12-hour counters. In addition, a permanent small seconds as well as a weekday and date display are available. The movement is temperature-stabilized and shock-proof – perfect for active everyday life or use in the cockpit.
Bracelet and wearing comfort
The watch comes with a high-quality stainless steel bracelet with aviator optics. Thanks to finely crafted links, safety folding clasp and solid workmanship, the strap not only offers the highest level of suitability for everyday use, but also pleasant wearing comfort. Integration into the case ensures harmonious lines on the wrist that combine sporty elegance and technical clarity.
Functionality
The 144 St Sa Pilot’s Chronograph impresses with its practical functionality: chronograph with two totalizers, complete calendar (day & date), tachymeter scale for speed measurement, luminous material on hands and indices for night readability and a pressure resistance of up to 20 bar. The magnetic field-protected construction up to 80,000 A/m makes this watch an ideal tool for demanding environments – whether in the cockpit, in everyday life or during sporting activities.
