The GUARDIAN Automatic series feature a 3-hand Swiss-made mechanical movement with date, automatic winding, smooth sweeping seconds and 25 jewels. The bold case is of impact-forged, surgical grade 316L stainless steel and precision machine sculpted. The screw-down crown is placed in the signature 10 o'clock position for anatomical ease and distinction. A choice of wide, sculpted stainless steel bracelet or substantial, incredibly flexible, durable, and anatomically pleasing black rubber strap combine elegance and comfort. Those SISU timepieces are shielded by an anti-reflective pure sapphire crystal, the hardest and most scratch-resistant lens material used in the world of fine watch making.
