Powered by the self winding caliber 240, this reference operates with a micro rotor architecture that allows for an ultra slim case profile while maintaining mechanical efficiency. The 18k rose gold case measures approximately 34.5 mm by 39.5 mm with a thickness of around 5.9 mm, emphasizing its dress watch orientation. Its sunburst ebony black dial is finished with applied gold baton hour markers and slender hands, delivering a clean visual field. The sapphire crystal case back reveals fine finishing, including Geneva striping and perlage, while the movement offers a power reserve of approximately 48 hours.

Rather than relying on complexity, this model expresses refinement through proportion and surface treatment. The elliptical case is mathematically derived from the golden ratio, giving it a natural visual harmony that sets it apart from traditional round designs. It is a watch built for collectors who value form, balance, and understated mechanical sophistication.

Alternative Reference Context: The contemporary 5738 Golden Ellipse family includes the 5738P-001 in platinum, 5738R-001 in rose gold and 5738/1R-001 in rose gold with an integrated chain-style bracelet. The 5738/1R-001 is a separate reference, not a bracelet variation of the 5738R-001.

Dial Variation: For the specific 5738R-001, Patek Philippe documents the ebony-black sunburst dial as the factory configuration. It should therefore not be presented as having multiple standard dial colors under the same 5738R-001 reference.
