This pre-owned Seiko Prospex Marine Master Professional 300M SBDX023 is available for purchase.

The Details:

One of the most notable characteristics of the Marine Master SBDX023 is the case. The monoblock case is just 2 pieces, the stainless steel case and the bezel. There is no case back. The case is polished using the Zaratsu Polishing Technique, a mirror blade polishing technique performed at the Grand Seiko manufacturing facility. The case is then treated with Seiko’s DiaShield coating to prevent scratches during wear. The crystal is sapphire, and the movement is a Caliber 8L35B movement based on Grand Seiko’s 9S55 movement. The dial is black with gold-colored hands, which are filled with Seiko’s own Lumibrite luminescence composition, as are the number plots and the first 20 markers on the bezel.

The Condition:

Included with this Seiko Prospex Marine Master Professional 300M Ref SBDX023 are the original outer and inner boxes, owner manual, guarantee certificate, all original hang tags, the stainless steel Seiko bracelet, and an additional Seiko black rubber strap with stainless steel Seiko buckle.
