Quick TakeThe Sinn 434 St B is far more than just its specifications; it's a symphony of classic style and subtle, sophisticated features. The blue sunburst dial whispers elegance, and the carefully applied, rhodium-plated appliqués add a touch of vintage flair. But it's all business where it counts. The temperature-stabilized, high-precision quartz movement, shielded by [Q] Technology, is the reliable heart, beating with exceptional accuracy, encased within steel armor. The sapphire crystal, anti-reflective on both sides, grants a clear view into this miniature world. Water-resistance up to 10 bar? Bring on the elements. It’s an accessory, and a loyal, dependable ally. The 34mm case diameter might be considered demure, however, it's that same size that allows the 434 St B to slip unassumingly under a cuff. The 434 St B is the essence of refined resilience.

DescriptionThe Sinn 434.012, designated as the 434 St B, is characterized by its meticulously engineered construction and refined aesthetics. The watch case, with a diameter of 34 mm and a thickness of 8 mm, is fabricated from polished stainless steel. This material selection ensures durability and resistance to corrosion. The case back is screw-fastened and constructed from a nickel-free material to prevent potential allergic reactions. Band lug width is precisely measured at 18mm. The watch's total weight, excluding the attached strap, is documented as 34 grams. The design meets DIN 8310 standards, ensuring it is resistant to water ingress at pressures up to 10 bar and safe for low-pressure environments. The front of the watch is shielded by sapphire crystal glass, noted for scratch resistance and treated with an anti-reflective coating on both inner and outer surfaces to optimize visibility under various lighting conditions.

The dial of the 434.012 is electroplated with a blue finish and enhanced with a sunburst decoration, adding to the visual detail. Time indication is accomplished via rhodium-plated appliqués, manually affixed to the dial surface. The hour and minute hands feature luminescent material that enables legibility in low-light situations. A feature of the watch, and notated on the dial with a [Q] symbol, is the special shielding used to reduce the impact of electromagnetic radiation emitted by the movement. The Sinn 434 St B houses an ETA E64.101 quartz movement. This movement is temperature-stabilized for enhanced accuracy and includes a seconds stop function (also know as a "hacking" function). The movement is built with eight bearing jewels and is classified as anti-magnetic, conforming to the standards defined by DIN 8309.
