The Sinn 104 is a modern pilot’s watch that has earned a devoted following for its blend of tool-watch functionality and everyday versatility. Introduced as part of Sinn’s core lineup, it channels the brand’s aviation roots without leaning on vintage reissues, offering a clean, contemporary design that collectors appreciate for its utility and understated style. Its German origin is evident in the crisp dial layout and practical features, making it a go-to choice for those seeking a reliable daily companion with genuine pilot heritage.

The 41mm stainless steel case strikes a balance between presence and comfort, while the bi-directional countdown bezel and high-contrast dial ensure legibility under any conditions. Inside, the 104 uses the automatic Sellita SW220-1 movement, chosen for its reliability and easy serviceability. Water resistance is rated to 200 meters, making it equally at home in the cockpit or on the water—an unusual versatility in this price segment. The sapphire crystal and display caseback add to its appeal for those who appreciate robust construction and a view of the movement.

Reference numbers for the Sinn 104 vary by dial color and strap options, with the 104 St Sa (black dial, steel case) being the most sought-after, while variants like the 104 St Sa I W (white dial) offer a different aesthetic. Prices tend to fluctuate based on dial color rarity and condition, with limited editions or discontinued variants commanding a premium. When buying, check for the original Sinn-supplied bracelet or leather strap, as these can affect value, and confirm the presence of box and papers, which are often expected by collectors in this segment.
