Up for sale is my Seiko Marinemaster 300 SBDX001 with a July 2014 production date. This one has the best crown action of any MM300 I’ve owned, screws in and threads very easily. It’s been worn daily so it has scratches on the case, bezel and bracelet as you can see from the photos. There's a heavier scratch at the lower right lug you can see from the photos. Keeping good time.

The package includes everything you see in the second photo: the watch on the bracelet, extra links (missing one collar), rubber strap, inner and outer boxes, warranty card, manual and hang tag.

$1425 including PayPal fees. Lowball offers will be ignored. No trades. I will pay for insured shipping to the CONUS only (I will not ship to other countries - please do not ask if I will) and the watch must be shipped to a PayPal verified address. I have had hundreds of successful transactions on various watch forums with impeccable references and I would prefer the buyer have some references as well.
