Louis Erard’s Golden Edition of Le Régulateur Louis Erard x atelier oï pairs a 42mm polished steel case with a gold-toned, radially engraved dial and three blue hands arranged in a regulator display. Reference 85237AA56.BVA175 is limited to 18 pieces and is listed at CHF 3,750 excluding tax. The official listing currently shows a waiting list; availability can change.
What makes the Golden Edition distinctive?
The dial is the focal point: 60 engraved lines radiate across its gold-toned surface, catching light differently as the watch moves. Louis Erard describes the collaboration as a new interpretation of Le Régulateur, using shades of gold and blue. The earlier design brief, reproduced by the brand, was “To radiate from the centre outwards.” Louis Erard’s earlier atelier oï collaboration page explains that the asymmetrical rays create reflections and contrasts, while the hands bring time into the composition.

The official specification describes the dial as “Black Or” slate grey, with matte and polished finishes. That wording sits alongside the product description’s gold-and-blue palette; the overall effect is a golden-looking dial rather than a flat, uniform gold surface. Monochrome Watches describes it as sundial-inspired.
How to read the regulator dial
Unlike a conventional watch, which usually places the hour and minute hands together at the centre, this regulator separates the indications. The short blue hour hand is at 12, the central blue hand shows minutes, and the small-seconds hand is at 6. The 60 engraved divisions form the minute track, with every fifth line more pronounced, according to Monochrome Watches.
#1 Best Overall
- Distinctive Dial Layout: The Junghans max bill Regulator features a distinctive dial design with a central minute hand, while the hour and second hands are decentralised.
- Automatic Movement: Powered by a self-winding automatic movement with a 38-hour power reserve, ensuring reliable timekeeping without the need for a battery.
- Polished Stainless Steel Case: The watch comes in a polished stainless steel case with a diameter of 40mm. The case back is secured by four screws, enhancing durability and providing a secure fit.
- Anti-Reflective Sapphire Crystal: Equipped with an anti-reflective sapphire crystal, the watch offers excellent clarity and scratch resistance, ensuring that the dial remains easy to read under various lighting conditions.
- Stainless Steel Milanaise Bracelet: The timepiece is paired with a stainless steel Milanaise bracelet, adding a touch of sophistication and comfort while maintaining the watch’s refined appearance.
- Hours: the small subdial at 12 o’clock.
- Minutes: the long central hand, read against the radial minute divisions.
- Seconds: the small subdial at 6 o’clock.
All three are blue baton hands, giving the display a consistent visual link to the blue strap while keeping the separate readings legible.

The movement’s separated indications are what make the watch a regulator; the approximate 38-hour reserve is the brand’s stated figure, not an independent performance measurement.
