SEIKO Prospex MarineMaster Professional 300M SBDX017

Proper tool watch, this. Featuring a 44.3mm steel case, the excellent 8L35 Automatic movement, black dial with super-strong lume, quick adjust clasp and one of the finest uni-directional bezel actions you'll find anywhere. Now discontinued, they are highly sought after for very good reason.

This particular piece is in TZ Good condition. Case shows a few scratches and swirlies from regular wear, and there are a few marks on the rear of the lugs from strap changes. It has been graded as good rather than excellent due to some tiny pin dents/nicks on the sides of the case. Please see images for full condition details.

Bracelet is full size, and still retains stickers on the clasp. Looks to have been unworn.

No known service history. Currently running at COSC timing.

Comes with outer sleeve, inner box, instruction manual, warranty booklet (blank), hang tags, Seiko rubber strap and Watch Vault cleaning cloth.

This is a highly sought after piece in great condition - don't miss out.
