Quick TakeThe Sinn 104 St Sa I is more than a mere instrument; it is an experience for the wrist. A nod to classic aviation timepieces, it marries rugged functionality with understated refinement. Feel that solid 41mm stainless-steel case, a true companion for everyday wear and a subtle statement to those in the know. The crisp, matte-black dial is all about utility, but the gleaming indices whisper an appreciation for high-quality details, not to forget the smooth sweep of the seconds hand, powered by that reliable SW220-1 automatic movement. The bi-directional pilot’s bezel is a simple joy, firm clicks counting away elapsed minutes with positive assurance. It isn't a watch boasting, but it does demonstrate quality, from its sapphire crystal to its 20-bar water resistance, and the day-date display is just one more practical touch, adding to a feeling of preparedness. The Sinn 104 is ready for wherever life's journey takes you, while the included vintage-style, dark brown cowhide leather strap, with contrasting stitching, adds more flavor.

DescriptionThe Sinn 104 St Sa I, reference 104.010, is a traditional pilots watch adhering to stringent engineering standards. The case, constructed from polished stainless steel, measures 41 mm in diameter, with a lug width of 20 mm and an overall case thickness of 11.9 mm. The watch's weight, excluding the strap, is 73 grams. The case incorporates a screw-fastened transparent back constructed from sapphire crystal glass that provides anti-reflective coating on its interior surface, while the front crystal, also of sapphire, features anti-reflective coating applied to both sides. The screw-down crown aids in delivering water resistance up to 20 bar, meeting the criteria stipulated in DIN 8310 standards, and is also resistant to low-pressure environments. A captive pilot's bezel, which ratchets in minute intervals, is securely mounted and engineered to prevent detachment.

Powering the Sinn 104 St Sa I is the SW 220-1 self-winding mechanical movement. This caliber features 26 bearing jewels and oscillates at a frequency of 28,800 semi-oscillations per hour (4 Hz). Included in the movement are a seconds stop function, for precise time setting, and anti-magnetic properties, meeting the requirements of DIN 8309. The movement facilitates the display of hours, minutes, and seconds, along with both the date and day of the week. Legibility is crucial, and thus the matte black dial uses indices that are meticulously coated with luminescent material. Similarly, the hour, minute, and second hands receive a coating of the same luminescent compound. The bezel itself is marked with a luminous triangle at the 12 o'clock position, improving visibility in low light environments.
