Sinn 104 St Sa A I MG 104.0131

The Watch

Sinn stays true to its German heritage by delivering timepieces of impressive quality. Founded in 1961 by former pilot Helmut Sinn, the brand has been committed from the very beginning to crafting prestigious watches regardless of their inspiration. The two main inspirations for Sinn are diving and aviation. This timepiece, known as the 104 St Sa A I MG 104.0131, unmistakably bears the aviator's mark. The watch features a masculine stainless steel case measuring 41 millimeters in diameter. At 11.5 millimeters thick, the piece remains remarkably lightweight on the wrist thanks to its 74-gram case. To easily set the hands or manually wind the exceptional movement, you'll find a screw-down crown at three o'clock. Its rounded, grooved shape pairs perfectly with the steel case. The dial is protected by a sapphire crystal with anti-reflective coating. Setting itself apart from the many pilot-style watches, this model features a bidirectional rotating bezel with graduations up to 60 minutes and, most importantly, luminescent markers for functional readability in any light and any setting. This exceptional jewelry timepiece will win you over with its many qualities. Water-resistant to 20 atmospheres, the exhibition caseback of this watch sets it apart from the crowd - a sapphire crystal caseback that magically reveals the movement in action.

The Dial

Sinn makes a bold statement with a striking green dial that sets this model apart. The sunburst metallic green dial, with its rounded form, captures light beautifully. For instant, effortless readability, hour markers are arranged around the perimeter. In detail, the hour indices appear as clear, luminescent Arabic numerals, accompanied by short geometric appliques with the same luminescent treatment. The outer edge of the dial features a fine minute track for ultimate precision. At the center, three hands meet. While the hour and minute hands sport a distinctive design, the seconds hand is tipped with an elegant, razor-sharp arrow. Sinn has naturally given all three hands luminescent treatment. The date is displayed through two windows positioned at three o'clock: the left one shows the day, while the right one displays the date. Rounding out the aviation-inspired information: the German manufacture's signature sits below 12 o'clock, with the movement type indicated in the lower portion of the dial.

The Movement

At the heart of this pilot's watch beats an automatic movement. Renowned for its prestige, the Swiss-made caliber powering this watch's hands and displays is produced by Sellita. It is specifically the SW 220-1 caliber, featuring 25 jewels and a beat rate of 28,800 A/h. Additionally, this movement is protected against magnetic fields in accordance with the DIN 8309 standard.

The Strap

Sinn embraces a distinctly masculine, customizable aesthetic with a model featuring a lug width of 20 millimeters. To best suit your preferences, the brand gives you the freedom to choose your strap.

The watchmaker pairs a solid stainless steel bracelet in a two-link design with a brushed and polished finish. Designed to complement the case perfectly, it delivers a harmonious look on the wrist. It fastens with a deployant clasp with safety lock.

For a more classic look, Sinn offers a bracelet with multiple slender links in stainless steel. It blends elegance and masculinity with a polished and satin finish, fastening via a butterfly deployant clasp with hidden buckle.

For a sleeker, urban feel, the brand offers a choice of two calfskin leather straps. One is black with tone-on-tone stitching, while the other is medium brown with contrasting light stitching, delivered with the leather backing removed. Both fasten with an elegant silver pin buckle.

Finally, for a lighter, sportier option that still keeps things refined, the brand offers a black silicone strap. It fastens with a pin buckle matched to the case.

Water Resistance

This model offers a water resistance of 20 atmospheres, or 200 meters. Ladies and gentlemen, this is a watch that can accompany you on your deepest aquatic adventures! It's designed for freediving. Fully water-resistant, you can even use high-pressure washers with this timepiece on your wrist - no worries. Showering, bathing, lap swimming, and freediving are all covered. However, for scuba diving with tanks, we recommend a timepiece with a higher water resistance rating. Also, avoid operating the crown or pushers while submerged to protect the integrity of the mechanism.
