Quick TakeThe Sinn 105 St Sa UTC W is a testament to purposeful design. The stark white dial, punctuated by the vibrant orange UTC hand, creates a face that's both strikingly legible and uniquely Sinn. The bead-blasted stainless steel finish whispers of tool-watch practicality, while the sapphire crystal on both sides hints at the refined engineering within. This isn't a watch that shouts; it confidently communicates. It's the anti-bling, designed for those who value precise German engineering and the satisfaction of knowing that the 24-hour bezel, hardened with TEGIMENT technology, will stay securely put, thanks to its captive design. It's a horological companion for global travelers, navigators, or those that have a need to reliably keep track of a second time zone at a simple glance. The Sinn 105 embodies a robust elegance and a professional's approach, ideal for everyday functionality.

DescriptionThe Sinn 105 St Sa UTC W, designated by reference number 105.021, is meticulously constructed with a focus on functionality and durability. The 41mm diameter case, crafted from bead-blasted stainless steel, provides a robust enclosure for the SW 330-2 self-winding mechanical movement. This movement, featuring a self-winding mechanism, incorporates 25 bearing jewels and operates at a frequency of 28,800 semi-oscillations per hour. The movement also includes a seconds stop function, facilitating precise time setting, and antimagnetic properties that meet DIN 8309 standards. Note that the movement specifications are in line with the current production in Frankfurt am Main. Although unlikely, deviations are possible with pieces from sales partners due to ongoing technical enhancements.

The watch features a captive bidirectional rotating bezel. This bezel possesses 24-hour ratcheting and is finished with Sinn's Black Hard Coating applied over a TEGIMENT Technology base, enhancing scratch resistance. The screw-fastened case back, like the front, is fabricated using sapphire crystal, providing a view into the operation of the movement. The crystal on the front surface has an anti-reflective treatment applied to both sides, with treatment on the interior of the case back. The dial, a crisp matte white, features indices coated with luminescent material, as are the hour, minute, and second hands, ensuring visibility in low-light situations. Functionality extends to hours, minutes, seconds, a date display, and a second time zone displayed on a 24-hour basis using an orange arrow-shaped UTC hand. The watch case integrates a screwable crown design which is rated for water and pressure resistance to 20 bar, along with a low-pressure resistance certification and adheres to the water resistance standards defined by DIN 8310. The watch has a band lug width of 20mm, a case thickness of 11.9mm, and the case weight, without strap, is 73 grams.
