Aqualung marketed contract-built watches under its own name alongside the diving equipment sold in its catalogues and dive shops. These attractive divers (also known as “Skin 666” from the last three digits in the number on the case back) used contract cases manufactured by A. Schild, with thick beveled lugs and handsome brush finishing throughout. They were powered by the sturdy, no-nonsense A. Schild/Felsa Caliber 4004 movement. The crowning glory of this watch (aside from the actual crown on the bezel at 12 o’clock) is the absolutely gorgeous radium dial, in this case in outrageously beautiful preserved condition. Featuring generous plots of Radium luminescent material and large stylized hands, these Aqualung branded watches are highly sought after by diving enthusiasts and tool watch fanatics alike.
