Known as the 'Triple Six,' the Sea-Dweller 16660 was the first to feature sapphire crystal. Early models utilized matte dials, while later versions transitioned to gloss dials, before the 16600 replaced it in 1988. This specific watch features a Mark 1 matte dial, distinguishable by the alignment of the 'F' in 'Feet' with the 'E' in 'Superlative'.
