In this insightful post, WatchProSite's 'this_hobby_of_hours' introduces his latest acquisition, the Girard Perregaux Ref. 2499 with a striking black dial. He highlights the watch's ideal 38mm cushion case size and shares detailed imagery. This article delves into the nuances of GP's neo-vintage cushion-cased chronographs, offering valuable context for collectors exploring these often-overlooked references.






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.
Fits your wrist well
Love that case shape ))
Any idea which movement is inside of it?
2499 as well? This version was commissioned by the sultan of Oman. The crest of the royal family. I’m researching further. Small batch.
Finished and refined by GP of course. Best of both worlds… reliable and easy to service. And not just “plonked” in the case. GP refinished it all and also refines.
Yes, for those who know ++
