Super-O Boyer watch bracelet is composed by 3 rows of solid links which is designing for 2009 onward SEI Tuna models such as SBBN013, SBBN00E, SBBN023, SBBN029 & SBDX016. Actual lug sizes of these 2009 onward Marinemasters are slightly less than 22mm. For this reason, we have tailor made the 21.5mm stainless steel bracelet collections. 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. Item also included one pair of FAT spring bar (eg. generic SEI Dia. 2.5mm spring bar) to ensure the watch band is connected securely with your watch. Accompany with 2015 new released 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 idea for watch band with thickness approximate 4.0 - 5.0mm thickness. Today replaces your SEI Marinemaster into this unique aftermarket watch bracelet.
