This MiLTAT Super Engineer I is designing for 2009 onward Seiko 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.
You know how handsome is this MiLTAT Super Engineer I?!
