Chronograph Watches - Model 757 UTC S

The Duochronograph with Captive Rotating Bezel
 
 
 
 
 
 
Is it even possible to improve timepieces that incorporate so many different state-of-the-art technologies as the 756 model series? The answer to this can be seen - at first glance, no less. The captive pilot's bezel gives the new Model 757 a distinctive character among the technological instruments by Sinn. The bezel, like the case, is tempered using the TEGIMENT Technology. This provides ideal conditions for the special mechanism likewise developed by SINN to keep it permanently attached to the case so it won't get lost even under the toughest circumstances. The pilot's bezel has a black anodized aluminum insert for marking time. The triangular mark at 0 / 60 minutes immediately catches your eye thanks to its coating of special luminous paint. When you rotate the bezel, you'll enjoy the fine mechanical precision and the rich clicking sound of the minute ratcheting. This makes the 757 model an even more versatile and useful instrument for professional use or private time comparisons.
