Titanium
Titanium is an ideal material for wristwatches, as no allergic reactions are known. With a specific weight of approximately 4.5 g/cm³, it weighs only 60% as much as stainless steel (specific weight around 7.8 g/cm³). Due to its low specific heat capacity and thermal conductivity, this material quickly adapts to body temperature, offering excellent wearing comfort, especially during colder seasons. Titanium’s low electrical conductivity also enhances wearing comfort by reducing electrical potential differences between various skin areas on the wrist.Titanium Grade 2: This is pure titanium, classified under material number 3.7035.
Titanium Grade 5: This is a high-strength titanium alloy with the material number 3.7165.
"Most developments are still ahead of us." This quote has motivated and guided Lothar Schmidt throughout his career. It was with this mindset that he embraced the opportunity to implement his development ideas when he took over the company in 1994. The first model series under his leadership showcased a distinctly technical design, which continues to shape the brand to this day. The models 244 Ti and 244 Ti F, crafted from titanium, stand out not only for their outstanding readability but also for features such as magnetic field protection and exceptional shock resistance. With these innovations, Lothar Schmidt elevated Sinn Spezialuhren to a new level of technical excellence.
Another manufacturing highlight in titanium is the Model Series 243, introduced in 2009. For the first time, the finish combines polished and satin-finished surfaces with a case made from high-strength Grade 5 titanium.
