Up for sale is my Seiko SBDX017 MM300. Purchased last April 2018 from, when they only had five remaining in stock at the time. I babied the hell out of the watch, so I'd say the watch is in pretty good condition. The only sort of diving I ever did with it was of the desk variety. Not a single drop of water touched the case. Diashield is as advertised, as I'm hard-pressed to find any scratches or nicks on the case except for perhaps the lugs, since I did numerous strap changes. Most signs of wear is relegated to the caseback. Crystal is perfect. Bezel action feels great. Crown engagement feels smooth. Alignment looks spot on. Ratchet clasp extender works perfectly. Bracelet was never worn, so that's pretty much new. Comes with the Crafter Blue strap that it's pictured with. The strap was sized for a ~6.75 inch wrist, but of course can be made shorter or longer with micro adjustments, cutting more pieces of the rubber, or clasp extender. Comes with all papers (warranty is unsigned/unmarked), box, and stock rubber strap.
Price: $1975 for U.S. buyers via Paypal. Shipping and Paypal fees will be covered on my end. Will also consider international shipping, but you will have to pay extra for that. The only watch I will consider trading this in for is a Grand Seiko Snowflake, with cash on my end to make up the difference.
Feel free to pm for any questions. Thanks!
