Patek Philippe Calatrava 'Cortina 50th Anniversary' Ref. 5057G

Partially verified

The Patek Philippe Calatrava 'Cortina 50th Anniversary', reference 5057G, is a wristwatch produced in a limited edition of 100 pieces to mark the 50th anniversary of the Cortina Watch retailer in Singapore. It is constructed with a 36mm 18k white gold case featuring a bezel decorated with a 'Clous de Paris' hobnail pattern. The dial incorporates a mix of elements including Roman numerals in the upper section and, in the lower half, sub-dials for the subsidiary seconds and power reserve indicator, alongside a moon phase and date display. The watch is powered by the self-winding Caliber 240 movement, which is equipped with a micro-rotor visible through the case back. This reference is documented as a collector's piece featuring a blend of design elements from the Calatrava collection and the 5712 model.

Object description

Case and Bezel Construction

The timepiece features an 18k white gold case measuring 36mm in diameter. The bezel is a defining aesthetic element of this reference, finished with a 'Clous de Paris' hobnail texture.

The case construction is designed to house the movement while maintaining a profile described as ideal for a classical watch. The photos depict a polished case finish contrasting with the intricate, repetitive pattern on the bezel.

Evidence for this section
  • “بدنه ۳۶ میلی‌متری از جنس طلای سفید ۱۸ عیار”
  • “بزل طلای سفید است که با سه ردیف از طرح مشهور «Clous de Paris» یا همان الگوی میخ‌مانند تزئین شده است”

Dial and Complications

The dial layout organizes multiple functional displays within a single aesthetic framework. Roman numerals are applied to the upper portion of the dial, while the lower section is reserved for the sub-dials and complication readouts.

The dial features a subsidiary seconds dial, a power reserve indicator, and a combination moon phase and date display. This configuration is reported to draw inspiration from both the 5712 model and the broader Calatrava collection.

Evidence for this section
  • “در نیمه بالایی صفحه از اعداد رومی استفاده شده است، در حالی که در نیمه پایینی صفحه، نمایشگرهای پیچیده شامل نمایشگر فاز ماه، تاریخ، ثانیه شمار فرعی و نشانگر ذخیره انرژی با نظم و زیبایی خاصی قرار گرفته‌اند”
  • “عناصری از مدل 5712 و کلکسیون Calatrava را در خود جای داده است”

Movement and Edition Details

At the heart of the 5057G is the Caliber 240 movement, characterized by its integrated micro-rotor. This automatic movement is exposed via the case back, allowing the user to view the mechanical components.

The production of this reference was strictly limited to 100 units to honor the 50th anniversary of the retailer Cortina Watch. This limited production run is a significant factor in the piece's classification as a collector's item.

Evidence for this section
  • “در پشت این ساعت، موتور کالیبر 240 با میکرو روتور که یکی از شاهکارهای کلاسیک این برند است، قابل مشاهده می‌باشد”
  • “تولید آن به تعداد محدود ۱۰۰ عدد محدود شده است”
