ZRC Securicode Diver 300 Men’s Luxury Swiss Watch | 39mm CuSn8 Bronze Case with Black Ceramic Bezel, Black Guilloché Dial and Brown Vintage Leather Strap – Limited Edition of 200 (SC39463)

Securicode: A 120th Anniversary Tribute to the 1958 Legend

The ZRC Securicode Diver 300 Bronze (SC39463) is a remarkable horological achievement, launched to commemorate ZRC’s 120 years of pioneering Swiss engineering. This specific model is a faithful yet modernized reinterpretation of the legendary 1958 Securicode—a watch that laid the foundation for the French Navy’s diving equipment. Unlike the standard steel editions, the SC39463 is a Limited Edition of only 200 pieces worldwide, making it one of the most sought-after references for South African collectors. It represents a “retro-chic” philosophy where the ruggedness of professional diving meets the refined aesthetics of luxury horology. For the enthusiast who values historical narrative and technical exclusivity, the Securicode Bronze is an unparalleled choice.

Visual Audit: Bronze Patina and Ceramic Precision

Our visual audit confirms a striking interplay of “living” metal and high-tech ceramics. The 39mm case is forged from CuSn8 Bronze, a marine-grade alloy that will oxidise over time to create a unique, dark patina based on the wearer’s environment—making every watch truly one-of-a-kind. This is contrasted by a Jet Black Ceramic Bezel Inlay, which is virtually scratch-proof and provides a permanent, deep lustre. The dial is a masterpiece of texture: a Double-Thickness Guilloché Brass Dial in deep black, featuring applied faceted indices. The handset is the iconic “Magnum” type, filled with high-performance Super-LumiNova® for surgical legibility. The lollipop seconds hand and the discrete date window at 3 o’clock ensure the dial remains balanced and functional without compromising its vintage-inspired symmetry.

Technical Specifications

Mechanical Functionality: The Sellita SW200-1 Elaborated

Behind the screwed steel case back lies the Sellita SW200-1 Elaborated calibre. ZRC has opted for the “Elaborated” grade, which is superior to the standard version found in many luxury watches. This movement is specifically adjusted in three positions to achieve a tighter accuracy rating of +/- 7 seconds per day. Beating at 28,800 vibrations per hour (4Hz), it features 26 jewels and a 38-hour power reserve. A key technical innovation is the Programmed Deformation Case Back. As the watch descends, the pressure actually increases the hermetic seal of the case back against the gasket, a design inspired by submarine airlocks. This allows the SC39463 to be rated for 300m while successfully passing pressure tests down to a staggering 800m depth, ensuring total security for professional divers and coastal adventurers alike.

The South African Connection: Resilience and Style

The ZRC Securicode SC39463 is perfectly suited for the South African lifestyle. The 39mm case diameter provides a “goldilocks” fit—substantial enough for an active day at the coast, yet slim enough (13.4mm) to fit under a blazer for a dinner in Cape Town. The Brown Vegetal-Tanned Leather strap is particularly noteworthy; it is moisture-resistant and designed to age alongside the bronze case, enhancing the “vintage explorer” aesthetic. For those living near the Atlantic or Indian Oceans, the bronze’s natural resistance to saltwater corrosion makes it a practical, high-performance material. The Blue Anti-Reflective Coating on the 2.9mm thick sapphire crystal ensures that even under the harsh South African sun, the dial remains perfectly legible with zero glare.
