Platinum PT750

Inspired by platinum, the PT750 embodies elegance, simplicity, and understated luxury. Its smooth curves and refined details reveal a timeless beauty that grows more captivating with each interaction.

Appearance

To make the 75% layout appear more slender visually, we have stretched the left and right bezels and added two meticulously designed characteristic lines to visually separate the bezels, creating a more balanced and harmonious overall proportion.

The PT750 replaces all the rigid, sharp lines with gentle curves and graceful arcs. These flowing curves soften the metal's industrial feel, creating a rounded aesthetic while maintaining a sense of strength.

Badge & Weight

We've also added a lucky clover emblem on the front badge and weight

a charming detail hoping that it brings good fortune to your work and life as it accompanies you.

Bold Use of G3 Curvature

G3 curvature is the design core and soul of the PT750, which significantly increases the complexity and cost of production but is entirely worth it for the unique appearance it creates. From every viewing angle, the G3 curvature design ensures smooth and natural lines, transforming the PT750 into a refined piece of art on your desk.

What is G3 Curvature

G3 curvature is a three-dimensional surface design featuring smooth, consistent curves that flow across all directions and angles. Widely used in high-end automotive and aerospace design, it creates flowing, uninterrupted lines. The result is a softer, more refined appearance where each viewing angle shows seamless transitions without harsh edges or abrupt breaks. This gentle design also helps reduce visual fatigue during extended use, improving both comfort and aesthetics.

Different Levels of Curvature

G0 Continuity: Two surfaces meet at a point or edge, creating visible sharp angles and non-smooth transitions.

G1 Continuity: The surfaces' tangent directions match at their meeting point, but their curvature may differ, causing slightly sharp transitions.

G2 Continuity: Both tangents and curvature match at the meeting point, producing smooth, natural transitions.

G3 Continuity: The highest level of smoothness, where surfaces share matching tangents, curvature, and rate of curvature change. This creates a perfectly seamless appearance from every viewing angle.

Some Design Cases

The rounded corners of Apple iPhones exemplify similar curvature principles, creating soft, ergonomic screen edges. This timeless design has remained visually appealing through multiple generations.

Xiaomi's new logo, released in 2021, also extensively uses G3 curvature. The design took three years to develop, blending a sense of "vitality" with "mathematical beauty."

Application on PT750

Applied to the PT750, G3 curvature creates a smooth, natural appearance from every angle. The design enhances both visual appeal and tactile comfort with seamless transitions that feel refined and silk to touch. From the top case waistline to where the bottom case meets the weight, G3 curvature delivers a consistently elegant, luxurious experience.
