Description
The Ref. 15703ST is an architectural celebration of the House’s legendary sports-luxury DNA, optimized for the depths. The 42mm case is expertly crafted from satin-brushed stainless steel, featuring the iconic octagonal bezel secured by eight polished hexagonal screws. Unlike standard models, this Diver reference incorporates an internal rotating bezel operated by a specialized crown at 10 o’clock, providing a definitive “pay-off” in terms of functional safety and a streamlined external profile.
The construction is grounded in the Maison’s legendary savoir-faire, featuring the self-winding caliber 3120. This movement acts as an “automated revenue system” of precision, noted for its reliability and its beautifully decorated 22-carat gold oscillating weight, visible through the caseback. The high-contrast black dial is designed for maximum legibility, featuring white gold applied hour-markers and oversized hands, all treated with a high-performance luminescent coating for clarity in low-light conditions.
The 42mm frame is built for a high-frequency lifestyle, offering an ergonomic fit on a black rubber strap with a stainless steel pin buckle. With a professional-grade water resistance of 300 meters, the watch is equipped with a screw-locked crown and a glareproofed sapphire crystal to withstand extreme pressure. Whether navigating the professional circles of Nairobi or engaging in maritime travel, this Diver is a definitive investment in the evolution of the luxury sports watch and functional Swiss craftsmanship.
