Quick TakeThe Sinn 1739 St I S is a quiet storm of horological goodness. It's the watch that whispers quality, not shouts it. The 39mm case is a masterclass in understated elegance – perfectly sized to slip under a cuff but with enough presence to stand on its own. And that dial, a rich black with sunburst finish, is a dynamic canvas for the hand-applied, rhodium-plated indices and hands to shimmer. Don't mistake its refined looks for fragility. This watch can play just fine, with a water resistance of 10 bar. Flip it, and sapphire reveals the self-winding SW300-1 ticking away, a small reminder the best view can come in unexpected places. Its black calfskin leather is a perfect pairing, for those who like to be refined. This is more than a watch; it's an exercise in purpose-built, high-quality German design.

DescriptionThe Sinn 1739 St I S, designated by the reference number 1739.012, is constructed with a focus on achieving an understated yet technically proficient design. The watch case, fabricated from polished stainless steel, measures 39mm in diameter and 9.1mm in thickness, exhibiting proportions intended for versatile wearability. A band lug width of 20mm allows the integration of a variety of strap options. The case back is screw-fastened, assisting the watch in meeting the DIN 8310 standard for water resistance. This confers a water and pressure resistance rating of 10 bar, alongside resistance to low-pressure environments. The crown also includes Sinn D3-System technology. Total watch weight sits at 52 grams, without a strap included. Front crystal made of sapphire, and treated with anti-reflective coating on both sides. The transparent case back is made of sapphire crystal as well, but is only anti-reflective on its interior surface.

Powering the timepiece is the SW300-1, a self-winding mechanical movement featuring 25 bearing jewels. This caliber operates at a frequency of 28,800 semi-oscillations per hour (4 Hz), contributing to the smooth sweep of the seconds hand. The movement's design provides antimagnetic properties, meeting the standards outlined in DIN 8309. The 1739 St I S displays hours and minutes via its central, rhodium-plated hands. These hands, along with the dial appliqués, are meticulously attached by hand. The dial itself is electroplated black and features a sunburst decoration, adding a degree of visual depth.
