Classic With A Twist.
There are watches that follow rules, and then there’s the Ellipse. Introduced in 1968, Patek Philippe’s Ellipse line was never about symmetry or playing it safe—it was about balance, proportion, and that mysterious sweet spot between a circle and a rectangle. Based on the Golden Ratio (yes, that thing from your high school geometry class), that ancient formula for beauty that somehow makes everything look just right. It became one of Patek’s most iconic shapes, a kind of quiet rebellion against the round.
This reference, the 3598, brings a bit of edge to the story. Literally. The top and bottom of the case taper to soft points, giving the familiar ellipse silhouette a subtle, distinctive shift. It still wears like an Ellipse but with a sharper point of view.
It’s from the 1970s, a decade that knew how to dress up, and it shows. The case is a hefty 18k yellow gold jumbo, measuring 30 x 35mm. It wears like a confident nod to vintage elegance, without ever feeling delicate. The deep blue sunburst dial is exactly the combo collectors and enthusiasts pine for—blue and gold, the power couple of the Ellipse family.
Inside is the manual-wound Caliber 16-250, ticking away with 18 jewels and a whole lot of history. And let’s not skip over the crown. That oversized, emblem-stamped gold crown doesn’t just look good—it feels good to turn. Satisfying in the same way a really well-designed volume knob is. If you know, you know.
You also get the original matching Ellipse buckle in 18k gold, a touch that makes the whole experience feel considered from top to toe. Continuity in design is rare. The buckle matching the watch isn’t just a bonus—it’s part of the whole thesis.
This is one of those pieces that doesn’t ask for attention, but gets it anyway. Clean, confident, slightly unconventional. The kind of watch that makes people lean in a little closer.
And for those who know the Ellipse line, this 3598 is the one that makes you pause. It’s a classic, but it doesn’t feel like it's trying to be one. It just is.
This watch is in excellent condition.
The case retains its original lines albeit some light markings from wear.
The dial, crystal and hands are mint.
The case back has light tool markings near the opening, very minor.
