Ahoi Glashütte! Forty millimeters across, our new watch is extra large and has an extra large date to match. Being waterproof down to 200 meters means it's a great accompaniment for swimming and sport. In addition to a waterproof fabric strap, it comes with one made from horse leather as well, which turns the watch from sporty to dressy in a flash. The Zeta movement ticks reliably away beneath the extra-strong sapphire glass base.
