Quick TakeThe Sinn 434 St Mother-of-Pearl W is where classic watch design meets modern, thoughtful engineering. This is no delicate flower; the 34mm stainless steel case houses a surprisingly robust, temperature-stabilized quartz movement, shielded against magnetism and capable of withstanding 10 bar of pressure. While being water resistant. It's even resistant to low pressure environments. The shimmering mother-of-pearl dial, adorned with hand-applied Roman numerals, adds that luxurious element of charm, and the sapphire crystal, anti-reflective on both sides, offers a view that is at once elegant and resilient. The [Q] technology is a subtle reminder of Sinn’s commitment to going the extra mile, reducing electromagnetic emissions. This isn't just a pretty accessory; it's a carefully considered, remarkably robust, high precision, timepiece made in the spirit of timeless elegance. With it's 8mm thick case, this beauty should have no trouble sliding under the cuff.

DescriptionThe Sinn 434.011, also identified as the 434 St Mother-of-Pearl W, represents a refined expression of horological engineering tailored for feminine aesthetics. The watch case, meticulously crafted from stainless steel, undergoes both polishing and satinizing processes, culminating in a sophisticated, durable finish. Measuring 34 mm in diameter and 8 mm in thickness, the case dimensions adhere to traditional proportions for a ladies' timepiece. The total weight, exclusive of the bracelet, is a mere 34 grams. This design integrates a screw-fastened case back, ensuring the integrity of the internal components, and it importantly omits nickel to minimize potential allergic reactions. The lug width is specced at 18mm.

The dial is made of Shimmering white mother-of-pearl. The time display utilizes hand-applied, rhodium-plated Roman numeral appliques at the cardinal positions, contributing to legibility and classic design. The hour and minute hands receive a luminescent coating, facilitating time reading under diminished light conditions. Protecting the dial assembly is a sapphire crystal, chosen for its superior scratch resistance. This crystal is treated with an anti-reflective coating on both inner and outer surfaces to maximize clarity. The watch demonstrates resistance to environmental factors: it meets DIN 8310 standards for water resistance, maintaining integrity up to a pressure of 10 bar. Furthermore, it is engineered to withstand low-pressure environments. A core feature is the inclusion of Sinn's [Q] Technology, as indicated on the dial, this feature is key in minimizing the electromagnetic radiation. Inside, an ETA E64.101 quartz movement provides timekeeping functions. This movement is a temperature-stabilized, high-precision caliber containing eight bearing jewels. It includes a seconds stop function (commonly known as "hacking") for precise time setting. Moreover, the movement is shielded to meet the anti-magnetic standards outlined in DIN 8309.
