The Louis Erard Le Regulateur (Ref. 85340AA01) represents exceptional Swiss horological craft, uniting refined case proportions, robust precision engineering, and distinctive dial architecture. Presented in verified brand new / unworn condition, this distinguished timepiece exemplifies Louis Erard’s commitment to enduring quality, ergonomic wrist presence, and unmistakable mechanical distinction.

Louis Erard Le Regulateur Architecture & Case Construction

Crafted in high-grade Stainless Steel, the exterior geometry of the Louis Erard Le Regulateur balances assertive sport-luxury contours with tailored elegance. The case measures 40mm in diameter, engineered with precise multi-angled beveling, alternating brushed and mirror-polished surfaces, and durable case seals designed to withstand daily environmental exposure. A scratch-resistant sapphire crystal with anti-reflective coating protects the multi-dimensional dial, ensuring pristine legibility in diverse lighting environments.

Every ergonomic detail on the case profile and bracelet integration has been engineered for all-day comfort. The winding crown functions smoothly with dual-gasket protection, maintaining dependable water resistance across varying atmospheric pressures. Beneath the sapphire crystal, hand-applied faceted hour markers and precision-finished hands provide intuitive readability at a glance.

The solid caseback construction protects sensitive balance assembly components against ambient magnetic fields and everyday micro-vibrations. Precision-fitted lug interfaces secure either a supple leather strap or solid link bracelet, fastened by an ergonomically sculpted deployment clasp for maximum security on the wrist.

High-Precision Movement Engineering

At the mechanical heart of this Louis Erard Le Regulateur beats an advanced Swiss mechanical caliber calibrated to stringent timing tolerances. Incorporating high-efficiency escapement components, temperature-compensating balance spring metallurgy, and shock-resistant jewel bearings, the movement provides dependable amplitude and generous power reserve. The regulation conforms with COSC Swiss chronometer certification standards, verified across multiple positions on digital timing instruments in our horology atelier.

The caliber plates and bridges are decorated with classical Geneva ribbing, circular perlage, and chamfered edges, reflecting centuries of Swiss artisanal mastery. High-tolerance gear trains and friction-minimizing synthetic rubies deliver consistent torque delivery across the entire power reserve curve.

Verified Technical Specifications — Ref. 85340AA01
