SEIKO PROSPEX SBDC081 GREEN SUMO

This is the SBDC081 — the Sumo that decided green was the new black. Same hulking presence, upgraded guts, and a sunburst green dial that actually looks good getting wet. It’s a proper dive watch that wears like a statement: serious engineering, unmistakable colour, zero apologies.

Key Features

• Caliber 6R35 Automatic (with manual wind & hacking) — modern Seiko powerplant with serious stamina.
• ~70-hour power reserve — leave it on the dresser Friday night and it’ll still be ticking Monday morning.
• Green sunburst dial — catches the light, fades to deep forest in shade; it’s the “Hulk” flex done right.
• Sapphire crystal (with AR on some releases) — far tougher than old mineral; keeps the dial crisp under glare.
• 45 mm stainless case with strong finishing — big, bold, but ergonomically Sumo-shaped so it wears surprisingly well.
• 200 m / 20 bar water resistance — true diver spec; screw-down crown and sealed case = confidence in saltwater.
• Robust bracelet & clasp — solid-links bracelet with secure-lock diver’s clasp and extension; built to stay put.
• LumiBrite on hands, markers & bezel pip — actually useful glow, not party tricks.
