The Trematic ZY6 Ossidiana represents the pinnacle of Swiss watchmaking tradition, seamlessly blending timeless design with modern reliability. This 38mm automatic watch captures the essence of heritage through its refined two-tone dial and signature wedge-hour markers, delivering the precision and durability today's discerning collectors expect. Built to endure, the ZY6 combines a solid case construction with a screw-down crown and 100-meter water resistance, making it equally at home in formal settings or everyday wear. Superluminova C3 hands provide exceptional visibility in low light, while the coin-edge case back showcases the iconic Trematic anchor—a testament to generations of meticulous craftsmanship. This is a watch that transcends occasion: refined enough for black-tie elegance, robust enough for adventure. The ZY6 Ossidiana proves that vintage character and contemporary performance need not be mutually exclusive.
