Patek Philippe Golden Ellipse Ref. 3545/2 | 18k White Gold Bracelet | Cal. 23-300 | 1970s

Description

The Golden Ellipse is Patek Philippe doing restraint at the highest level. Ref. 3545/2 sits right in the heart of that idea. Introduced at the turn of the 1970s, this reference keeps the Ellipse philosophy intact while giving it a sharper, more architectural presence.

The case measures 27 x 32 mm and wears horizontally, lending it a subtle TV shaped profile without abandoning the Ellipse’s classical proportions. In white gold, the watch feels cool, deliberate, and quietly luxurious. The integrated textured white gold bracelet elevates it further, turning the watch into a complete design rather than a case strapped to leather.

The silvered dial is beautifully judged. Light texture across the surface, black painted baton markers, slim sword hands, and a Sigma signature at 6 o’clock that confirms the use of gold components on the dial. Nothing extra. Nothing missing. Just balance.

Inside beats the manual wind Calibre 23-300, finished to Geneva Seal standards. This movement is one of Patek’s most respected workhorses, known for its reliability, thin architecture, and traditional finishing. Everything is signed, case, dial, movement, bracelet, and clasp, exactly as collectors want to see.

This is a vintage Patek that doesn’t try to impress loudly. It simply assumes you know what you’re looking at.

Historical Significance

The Golden Ellipse collection represents Patek Philippe’s exploration of proportion, inspired by the golden ratio rather than traditional round case design. Ref. 3545 was introduced in 1969 and produced in several variations throughout the 1970s, making it one of the defining references of the era. The combination of white gold, integrated bracelet, and Geneva Seal movement places this watch firmly in Patek’s high-horology lineage. For collectors, it offers exceptional wearability, design purity, and a direct link to one of the brand’s most intellectually driven collections.
