In the world of horology, the fusion of historical inspiration with cutting-edge technology often yields timepieces that are not just tools for measuring time but works of art that tell a story. The Arnold & Son Longitude Titanium embodies this, offering a COSC-certified chronometer encased in robust titanium and adorned with a dial that speaks volumes of the brand’s maritime heritage.

A Watch with a Story

NEW Arnold & Son Longitude Titanium w/Kingsand gold dial

The Longitude Titanium’s design is a thoughtful homage to John Arnold, a luminary in the world of marine chronometers. His work was instrumental in the calculation of longitude at sea, revolutionizing navigation and saving countless lives. The vertical satin finish of the dial, mirroring the bracelet’s design yet highlighted by polished edges, not only captivates the eye but also connects the wearer to the vastness of the ocean that Arnold’s innovations once navigated.

Graphic Design Meets Historical Tribute

The layout of the Longitude Titanium’s dial is a deliberate nod to Arnold’s marine chronometers. The arrangement of the power-reserve display at 12 o’clock and the seconds counter at 6 o’clock, along with the hour and minute hands, aligns perfectly with the vertical axis, mirroring the standard set by Arnold himself. This design is not just aesthetically pleasing but rich in historical significance, blending the graphic with the maritime spirit.

Inspired by Cornwall’s Colors

The choice of colors for the Longitude dials draws inspiration from Cornwall, Arnold’s birthplace. The limited edition “Kingsand” model, with its sandy golden hue, alongside ocean blue and fern green variants, evokes the natural beauty of the coastal landscape. Each color not only adds a unique charm to the timepiece but also pays homage to the natural elements that were crucial to Arnold’s work and the era of exploration he represents.
