This limited edition Triptych Automatic takes design cues from classic, historical watches while taking advantage of modern manufacturing and finishing precision today. Powered by our proprietary automatic wandering hour movement, its completely mechanical.We used the best materials to create the Triptych Automatic a beautifully brushed case made of 316L stainless steel, colorful anodized aluminum module arms, padded croc-stamped Italian leather with full stitching, and Swiss-made Super-LumiNova minutes and hours. Every natural stone dial is different and makes each of these limited edition timepieces even more unique.Reading the time looks complicated but is actually quite easy. Simply look at where the hour meets the minutes. Thats it. As time passes, the next hour comes into view, and the geneva gear mechanism shifts the discs to their next position.**Variations in the natural stone will vary so the dial of the watch you receive wont match the picture exactly. If youre not comfortable with this, then we recommend purchasing the original Triptych Automatic.**
