And i have, thanks to you, one mounted on my sbbn015. It’s a perfect match with the head surfaces and wonderful strap, best flat vent out there period.These are simply the best and most comfortable straps SEIKO has offered in years if not ever. They beat the pants off a DAL1BP or an Uncle Seiko USGL831 for softness and feel. The rectangular vents are close to the original GL831 not the other wider groove of say the other new solars or such.
I have maybe 5 or more watches sporting these New Arnie straps - love them !
