Description from the seller
Seiko - Marinemaster Professional 300m "MM300" - SBDX001 - Men - 2011-Present
Lot Description:
Up for auction is a true icon of Japanese watchmaking: the Seiko Marinemaster Professional 300m, reference SBDX001. Known affectionately by collectors as the "MM300," this is a serious tool watch that punches far above its weight class, featuring a monobloc case construction and the high-end 8L35 automatic movement.
This specific example comes as a full set, including the original box, Japanese papers, manual, and the signature Seiko waffle-style rubber strap.
Condition Report:
Case: Excellent condition with minor signs of wear consistent with careful use. The monobloc (one-piece) case ensures incredible water resistance and structural integrity.
Dial & Crystal: Flawless matte black dial with high-relief LumiBrite markers. The Hardlex crystal is clear.
Bezel: The distinctive high-gloss black bezel rotates smoothly with the tactile "click" Seiko is famous for.
Movement: Powered by the Caliber 8L35, an undecorated version of the Grand Seiko 9S55 movement. It is running strongly and keeping excellent time.
Bracelet: Currently sized for a comfortable fit, the stainless steel bracelet includes the ratcheting diver’s extension clasp. Crucially, this lot includes two (2) extra original links, allowing the bracelet to be sized for almost any wrist.

Case Material: Stainless steel (Monobloc)
