Description

Sinn 104 St Sa I (Ref. 104.010) – Classic pilot’s watch with modern features

Housing and design

The Sinn 104 St Sa I combines the traditional design of classic pilot’s watches with modern technical attributes. The polished stainless steel case measures 41 mm in diameter and has a balanced case height of 11.5 mm – making it compact, robust and at the same time suitable for everyday use. The captive aviator bezel with minute detent can be rotated on both sides and has a black, scratch-resistant hard coating. The deep black dial has a clear and uncluttered design: white Arabic numerals, a full minute ring and slim, white-coated hands with luminous material ensure excellent readability. A sapphire crystal with an anti-reflective coating on both sides protects the dial from scratches and reflections – ideal for a wide range of lighting conditions.

Movement and technology

Inside, the tried-and-tested SW 220-1 automatic movement works in the version with day and date display. The caliber offers 26 jewels, a frequency of 28,800 vibrations per hour and a power reserve of approx. 38 to 42 hours. The clock displays hours, minutes and seconds centrally, supplemented by a window for the day of the week and date at 3 o’clock. The movement is non-magnetic in accordance with DIN 8309 and shock-proof – ideal for reliable use in everyday life or on the road.

Bracelet and wearing comfort

Our version is equipped with a dark brown cowhide leather strap in a vintage look from Sinn. The bracelet underlines the classic character of the watch with its subtle patina and natural structure. It sits comfortably on the wrist, fits perfectly with the overall aesthetics of the watch and is securely closed with a solid stainless steel pin buckle. The combination of high-quality leather, classic colourway and comfortable fit makes this band a stylish choice for everyday and leisure wear.

Functionality

The Sinn 104 St Sa I impresses with its practical versatility and maximum reliability: The rotating bezel with minute detent is ideal for measuring short intervals – for example, when flying, driving or doing sports. The day and date display are clearly legible, while the generous luminous coating on the hands and indices ensures clarity even in the dark. With a water resistance of up to 20 bar (200 metres) and vacuum protection, it is ideally equipped for almost every everyday situation and many outdoor activities. The combination of classic design, modern mechanics and robust execution makes the Sinn 104 St Sa I one of the most popular all-rounders in the brand’s portfolio – a real mission watch with style.
