Introduced in the late 1970s, this model incorporated the calibre 3035 automatic movement with a quickset date and increased water resistance, alongside the signature helium escape valve designed for saturation diving. Its 40 mm stainless steel case and black dial ensure legibility and durability under extreme conditions, making it a favorite among professional divers. This example is further distinguished by its Tiffany & Co double-signed dial, a rare and highly desirable feature for collectors.
