Descriptions :
ROLEX Stainless Steel "SEA-DWELLER" Diving Watch with Date & Gas Escape Valve. Ref.16660.
Dial :
Signed and Original Black Dial appears to have been slightly aged all round but is not bad at all as all the lettering are still very visible. Date at 3:00. Applied hour markings. Signed "ROLEX OYSTER PERPETUAL DATE" at 12:00 & "SEA-DWELLER 4000FT/1220M SUPERLATIVE CHRONOMETER OFFICIALLY CERTIFIED" at 6:00. Hands are all in Excellent/Mint condition. I will say the aging on dial was caused by sun-light.
