Girard Perregaux 1966 Blue Moon Steel DLC 40mm Blue & Sunray Motif Dial 49545-11-432-BH6A Girard Perregaux 1966 Blue Moon Steel DLC…

The Girard-Perregaux 1966 collection stands as one of the most enduring expressions of classical Swiss watchmaking, drawing its name and inspiration directly from the storied manufacture's founding year of 1791 — though the 1966 line itself pays homage to a pivotal era in the brand's modern history. Defined by clean, symmetrical case design and restrained elegance, the 1966 family has attracted discerning collectors who want a serious Swiss movement housed in a watch that never raises its voice.

Reference 49545-11-432-BH6A brings an unmistakably modern energy to the classic 1966 blueprint through its Blue Moon execution. The 40mm steel case receives a full DLC (Diamond-Like Carbon) coating, transforming what would be a conventional dress case into something altogether more purposeful and contemporary. DLC is prized for its exceptional hardness and scratch resistance, meaning the case retains its matte, dark finish far longer than conventional brushed or polished steel.

The dial is the emotional centerpiece of this reference. A rich blue sunray motif radiates from the dial's center, shifting character as light catches it from different angles — a hallmark of quality dial finishing that separates fine Swiss watches from lesser alternatives. Blue indexes complement the dial perfectly, creating a cohesive, monochromatic palette that is simultaneously bold and refined. The overall effect is a watch that commands attention on the wrist without resorting to excessive complication or ornamentation.

Powering this 1966 is an automatic movement, consistent with the calibers Girard-Perregaux deploys across the 1966 line — movements developed and finished in-house at the La Chaux-de-Fonds manufacture, reflecting decades of micromechanical expertise. The 40mm diameter is a considered choice, large enough to wear with authority yet slim and balanced enough to slide effortlessly beneath a shirt cuff, making this genuinely versatile across both formal and smart-casual occasions. The leather strap reinforces the watch's dress DNA while adding a layer of tactile comfort.

For collectors and first-time buyers alike, the Girard-Perregaux 1966 Blue Moon 49545-11-432-BH6A represents a compelling entry into genuine haute horlogerie from a manufacture with over two centuries of continuous production. It offers the rarity of DLC execution in a dress-watch format — a combination few Swiss houses attempt.
