For sale is my Seiko Blue Lagoon Turtle SRPB11, which has been professionally upgraded (and pressure tested) to flat sapphire crystal with inner AR by Duarte at North East Watch Works. This was a 6000 piece limited edition.

Comes with inner/outer box (outer white box shows a good bit of wear), papers, hangtag, bracelet with all links/collars/pins, OEM silicone strap, perfectly matched Barton Bands elite silicone strap, and original hardlex crystal. Shows minor wear from normal use including strap changing marks, plus one small (~2mm) ding to the non-crown side of the case. Bezel and chapter ring are well-aligned.

$525 shipped to US only. I will cover PayPal fees. Insurance/signature at buyer's request/expense. Please no trades. I've had 200+ good transactions on this and other watch forums and eBay feedback is available under the same username (where I've had 1900+ positive transactions). No returns unless the condition of the watch is materially misrepresented.
