S23635J1 PROSPEX Watch 1000M Quartz Diver's
The S23635J1 watch incorporates all the important features and innovation that made the original 1975 mechanical model and the 1986 quartz model so popular with the professional diving community. Water-resistant to 1,000 metres and helium-resistant, a requirement for saturation diving, it incorporates the famous one-piece titanium case with its protective outer casing guard that makes its shock resistance so outstanding. The outer protection is made of zirconia ceramic, a material that is seven times harder than steel, thereby further enhancing its resistance to impact. The watch comes with two extra-strong silicone straps - one black and one blue-grey - so it can be worn either over a wetsuit or directly on the wrist. Limited to 1,200 pieces worldwide.
