[Uncle] Super Engineer Bracelet (Seiko SPB15x "Willard")

Uncle's notes

If the Executive and Z199 had a baby, it would be the Super Engineer.  If you're a fan of the heavier (but comfortable) bracelets but want something a little less flashy, you'll love this one!  It features 5 beautifully chamfered interlocking links for a really neat look, and tapers from 20mm to 18mm.

The Super Engineer also features the flip-lock diver clasp to ensure it's ready for whatever adventure you're pursuing.  

What's included

One bracelet, one pair of end-links, one pair of 2.5mm spring bars.
