Measuring 44mm in diameter and 17.7mm thick, the case is crafted in 18k yellow gold with a titanium caseback and a scratch-resistant sapphire crystal. A unidirectional ceramic bezel and screw-down crown complement the water resistance rating of 3,900 metres (390 bar), reflecting the Deepsea's purpose-built depth capability.
The blue lacquer dial is fitted with yellow gold hands, displaying hours, minutes, and a running seconds hand alongside an instantaneous date with rapid setting. The stop-seconds function allows for precise time synchronisation. Power comes from the Rolex calibre 3235, an automatic movement running at 28,800 vph with 31 jewels, COSC-certified, and offering a 70-hour power reserve.
Worn on an 18k yellow gold bracelet, this reference 136668LB is presented with its original box and papers, with disclosure noted as 2024.
