Patek Philippe Rectangular Watches with 9-90 Caliber

The Patek Philippe reference 1593, introduced in 1944, is notable for its distinctive "Hour Glass" case shape. This design features a gentle curvature along the sides that tapers inwardly towards the center, creating a silhouette reminiscent of an hourglass. This unique case profile sets it apart from more conventional rectangular or tonneau-shaped watches of its era, making it a recognizable piece within Patek Philippe's historical catalog.

The watch is housed in a yellow gold case, measuring 23x37 mm. It is powered by the manual-winding caliber 9''', a movement known for its reliability and precision. The crystal is typically acrylic, with some examples featuring a faceted crystal at the narrowest part of the case, while others have a curved crystal. The fixed bezel frames a silver dial.

For collectors, the reference 1593 represents a distinctive design chapter in Patek Philippe's mid-20th century production. Its unusual case shape and the variations in crystal and case side profiles offer points of interest for enthusiasts. The reference appeals to those seeking a Patek Philippe with a strong aesthetic identity and a departure from standard case forms.

The Patek Philippe Calatrava reference 2442, introduced in 1948, is a notable example of a shaped watch within the Calatrava line, distinguished by its elongated, curved case design. This reference is known by several collector nicknames such as “Banana” and “Mimitabu,” reflecting its distinctive form. Its production numbers are estimated to be limited, contributing to its rarity and appeal among collectors of vintage Patek Philippe timepieces.

This particular reference was produced in rose gold, with case dimensions of 27 x 42.5 mm. The watch typically features a manual-wind movement, consistent with Patek Philippe's manufacturing practices for dress watches of this era. The crystal would have been a period-appropriate material, likely acrylic, protecting a dial that often developed appealing patinas over time.

Reference 2442 holds a significant place for collectors interested in Patek Philippe's mid-century design evolution and the brand's exploration of non-circular case forms. Its scarcity and unique aesthetic make it a sought-after piece, particularly examples with well-preserved dials and cases. It represents a specific design language from a pivotal period in the brand's history.

The Patek Philippe Calatrava reference 2471 stands out within the Calatrava collection for its distinctive shaped case, departing from the more common round designs.

It represents a period when the brand explored diverse aesthetic forms while maintaining its high standards of craftsmanship.

This particular reference features a rectangular case, often crafted from precious metals such as yellow gold.
