This Hexad watch band is designing for 2009 onward SEI Tuna models such as SBBN013 or other 21.5mm lug SEI diver or sport watch case with straight lug. Hexad watch band is a striking design first launched in recent years. Each link is composed of 3 massive Chamfer edge solid 316L stainless steel units and a curved solid end piece. Hexad is a contemporary version of the traditional O Boyer bracelet, but more thick & sturdy over 100 grams. Considering the comfort and sustainability, it bends smoothly following your wrist. Well-made solid 316L stainless steel links are assembled with screws instead of flimsy pins to keep its solidity and stability. (Compatible with original SEI 18mm buckle, if you want to install your original SEI clasp, please checks the size of your SEI clasp first.) This item includes one pair of FAT spring bars (Generic SEI Dia. 2.5mm spring bar) to ensure a more secure connection. Here introduce the latest technology of metal coating - "Diamond-like carbon" DLC coating. DLC is very resistant to abrasive and adhesive wear making it suitable for use in wristwatch accessories that may experience extreme contact pressure in rolling or sliding contact. The extreme hardness, wear-resistance, and slickness of DLC coating make it an ideal coating to apply to stainless steel watch bands. Accompany with V-Clasp double lock buttoned diver's clasp. V-Clasp was made from solid 316L stainless steel with extra 6 micro holes for flexible fine tune length adjustment. Featured in V shape safety lock, streamlined form & chamfer edged design to giving a more massive look. Chamfer double locks diver's buckle is ideal for watch band with thickness approximate 3.5 - 5.0mm thickness. Today replaces your SEI Tuna into this unique aftermarket watch band.
