This is the Rolex Sea Dweller, model 16600 that is the Rolex Submariners big brother.
The stainless steel case measures 40mm across and is 1mm thicker than the submariner and the sapphire crystal is also 1mm thicker than the submariner, making it able to go down to a depth of 4,000ft/1,220m.
With a helium escape valve, Rolex Oyster flip-lock bracelet, rotatable bezel and trip-lock crown, the Sea Dweller does not have the “bubble magnifier” window over the date, making it nice and smooth.
An incredible watch in great condition, this Rolex will be worn with pride.
