Girard-Perregaux 2598: Black Dial Asia Edition Guide

The Patek Philippe Reference 2499 is a highly significant perpetual calendar chronograph, representing a pivotal model in the brand's history of complicated wristwatches. It succeeded the Reference 1518 and introduced a larger case diameter and updated aesthetic, establishing a design language that would influence subsequent perpetual calendar chronographs from Patek Philippe for decades. The reference was produced in four distinct series, each with subtle variations in dial layout, pusher style, and case construction.

This reference typically features a case crafted from precious metals, most commonly yellow gold, though examples in rose gold and platinum are known. The case diameter is generally 37.5mm, housing a manual-wind movement, specifically the caliber 13''' Q. This movement integrates a perpetual calendar mechanism with a chronograph function, offering indications for day, date, month, leap year, and moon phases. The crystal is typically acrylic for earlier series and sapphire for later iterations.

The 2499 is highly sought after by collectors due to its rarity, complexity, and historical importance. It is considered a benchmark for vintage complicated Patek Philippe watches and represents the evolution of the perpetual calendar chronograph from the mid-20th century. The variations between the four series provide distinct collecting opportunities, with each series possessing unique characteristics that appeal to different connoisseurs.

The Girard-Perregaux reference 2598 is a chronograph model that was part of the brand's offerings in the late 1990s. This reference is distinguished by its specific design elements and material combinations, positioning it as a notable piece within Girard-Perregaux's neo-vintage chronograph production. It represents a period when the brand was exploring various aesthetic interpretations for its sportier timepieces, often incorporating a blend of traditional watchmaking with contemporary design trends. The reference 2598 is distinct from the Laureato Olimpico series, though it shares a similar production era.

This particular reference typically features a stainless steel case, housing an automatic movement. The case diameter is 38mm, providing a balanced presence on the wrist. The watch is fitted with a sapphire crystal, ensuring durability and scratch resistance. The movement offers a power reserve of 45 hours, a standard for automatic chronographs of its time. The water resistance is rated at 30 meters, suitable for everyday wear but not for immersion.

For collectors, the reference 2598 appeals to those interested in Girard-Perregaux's output from the late 20th century, particularly its non-Laureato chronograph offerings. Its production numbers were generally limited, contributing to its appeal among enthusiasts seeking less common variations. The watch represents a specific design language from Girard-Perregaux, making it a point of interest for understanding the brand's evolution in the chronograph segment during that era.

The Girard-Perregaux Laureato Olimpico reference 8017 represents a notable chronograph within the Laureato collection, distinguished by its sport-oriented design and limited production. This reference was introduced in the mid-1990s, offering a contemporary interpretation of the Laureato's integrated bracelet aesthetic combined with chronograph functionality. It stands as a distinct offering from the brand during that period, catering to collectors interested in modern chronographs with a heritage connection.

This particular reference features a 40 mm case, available in configurations such as steel and rose gold or full steel. The movement is an automatic chronograph caliber, providing reliable timekeeping and stopwatch functions. The crystal protecting the dial is sapphire, ensuring durability and scratch resistance. Water resistance is suitable for everyday wear, aligning with its sport chronograph designation.

Collector interest in the Laureato Olimpico ref. 8017 is often driven by its limited availability and specific dial variants. For instance, the steel and rose gold version with a tobacco grey dial saw a production of approximately 10 units, while the full steel version with an Yves-Klein blue dial had a slightly larger, though still limited, production run of around 200-333 pieces. These production numbers contribute to its appeal among collectors seeking rarer examples of the Laureato chronograph.
