Patek Philippe 5711 and 5146P Collection

The Patek Philippe Annual Calendar Moon Phases reference 5146, introduced in 2005, represents a significant offering in the brand's annual calendar complication lineage. This reference succeeded the popular 5035 and 5036 models, refining the aesthetic and technical presentation of the annual calendar with moon phases. It is characterized by its balanced dial layout, integrating day, date, month, moon phase, and power reserve indications in a legible and harmonious arrangement. The 5146 was produced in various precious metals, establishing itself as a core model within Patek Philippe's complicated watch collection for many years.

This particular iteration of the 5146 is presented in an 18k yellow gold case, measuring 39mm in diameter. It houses the self-winding Patek Philippe Caliber 324 S IRM QA LU, a movement known for its reliability and precision, visible through a sapphire crystal case back. The movement provides a power reserve of approximately 45 hours. A domed sapphire crystal protects the dial, and the watch is water-resistant to 30 meters, suitable for everyday wear but not for swimming or diving.

The reference 5146 appeals to collectors seeking a sophisticated daily wearable complication from Patek Philippe. Its annual calendar mechanism requires adjustment only once a year, at the end of February, offering practical convenience. The model was available with several dial variations and case materials throughout its production run, which concluded around 2020. The yellow gold variant with a silvery opaline dial offers a classic and understated presentation, aligning with traditional Patek Philippe aesthetics.

The Patek Philippe reference 5711/1A-011, part of the Complications collection, is distinguished by its white dial, offering a different aesthetic compared to other dial variations within the 5711 series. This particular configuration provides a clean and legible presentation, appealing to collectors who prefer a more understated yet refined look. It represents a specific iteration of a well-known Patek Philippe model, recognized for its integrated design.

The watch features a 40mm stainless steel case, housing the self-winding Caliber 26-330 SC movement. This movement provides a power reserve of 45 hours. The case is fitted with a sapphire crystal, contributing to its water resistance of 120 meters. The fixed bezel and integrated bracelet are characteristic elements of its construction.

This reference appeals to collectors interested in the evolution of Patek Philippe's offerings, particularly those seeking specific dial colors within established model lines. Its production run from 2019 to 2021 marks it as a relatively recent, yet now discontinued, variant. The watch's specifications align with Patek Philippe's standards for mechanical timepieces.
