The Wooly Mammoth Tooth Dial Color and grain are the earmarks of the dial crafted from fossil mammoth tooth . This relic of the giant that last roamed the Earth 10,000 years ago is occasionally discovered on the sea floor or riverbeds . When used for decoration , each tooth or remnant must dry for about 2 years before William Henry can begin to work with it . Vacuum stabilized with resin , the finished dial reveals unique patterns and colors that have been waiting ( at least ) 10,000 years to become a timeless story on your wrist . The dial is housed in a forged Damascus case , built with 300 layers of stainless-steel alloys and acid-etched to reveal the flowing patterns of the contrasting metals . The case is finished with a sapphire crystal and exhibition back revealing the Swiss automatic movement with a 38-hour power reserve . Water resistance is rated to 10 ATM / 100 meters , and the hand-crafted crocodile leather strap features a custom stainless deployant clasp for easy wear and adjustment .
chose to go with the Sellita SW 400 , a Swiss automatic time & date ( only ) movement without extraneous functions or complications , allowing the full impact of the rare materials to take center-stage .
All else being equal , the SW 400 is a slightly larger version of the SW 200 and fits very nicely into the 42mm case without looking lost in the see-through back . These high-grade movements are housed in grade 5 titanium , Damascus steel , and even Timascus ( Damascus Titanium ) – clearly putting the metallurgical roots and experience of the William Henry brand on full display . These watches are also built to high standards and are water resistant to 10atm , regardless of the case material .
Under the sapphire crystals , each dial represents more than just color , pattern , and texture . They actually embody time in several different ways :
The Superconductor dial is a wafer of a modern material originally created as a particle accelerator moving protons and electrons to 99.997 % the speed of light . It just so happens that the cross-section of this space-age material presents an intriguing pattern born from technology , and never used for its aesthetic value – until now .
The Timascus dial combines ancient metalworking techniques in a mélange of modern materials and historical metalsmithing where the Damascus style layering of metals dating back to 1,500 BC are applied to the more modern titanium , a metal not really in widespread use until the 1900s .
Travelling a bit further back on the William Henry materials time-line , we find the Mammoth Tooth dial . Crafted from the
