Jimjenkins shares his personal experience with the Patek Philippe 5550P Advanced Research, a timepiece that sparked considerable discussion upon its 2011 introduction. His detailed observations on the dial's dynamic appearance and the watch's understated profile offer valuable insights into living with this technically advanced perpetual calendar. This article explores why the 5550P, with its innovative Oscillomax technology, continues to be a compelling choice for collectors seeking both horological advancement and daily wearability.
The Patek Philippe Reference 5140 is a perpetual calendar wristwatch, succeeding the highly regarded Reference 3940. It maintains the classic Patek Philippe perpetual calendar layout, featuring day, date, month, leap year, and moon phase indications. The 5140 was introduced with a slightly larger case diameter than its predecessor, reflecting contemporary preferences while retaining a traditional aesthetic.
This reference is powered by the ultra-thin self-winding Caliber 240 Q, known for its micro-rotor construction which allows for a slender case profile. The movement provides a power reserve of 48 hours. The watch is presented in 18k white gold, rose gold, or yellow gold cases, measuring 39 mm in diameter, and is fitted with a sapphire crystal. It offers water resistance to 30 meters.
The 5140 appeals to collectors seeking a modern perpetual calendar with a direct lineage to Patek Philippe's established complications. Its production run from 2006 to 2019 saw various dial configurations, including opaline and silvery finishes. The watch is typically paired with a leather strap and a deployant clasp, consistent with Patek Philippe's classic offerings.
I can't say no more, you just described the perfect feeling to own this beauty
Now, silicon or no silicon? That is a question some brands, which used to use both silicon and no silicon escapements, start to think about. The no lubirification system is a very good point. But some watchmakers told me that you can adjust a movement with a conventional escapement, which is much more difficult with a silicon escapement. Or did I get it worng? About fiability, well, I didn't hear nothing which could be problematic about silicon escapements. Two of my Watches have one, and so far
