At 40mm, the 228235-0045 reference introduces one of the most unconventional dial materials in the Day-Date lineup, and this replica Day-Date 228235 features an Eisenkiesel stone dial set within an Everose gold configuration. Eisenkiesel, a natural quartz-based stone with iron inclusions, creates a deep reddish-brown surface with irregular veining that cannot be replicated synthetically. Each dial displays a unique pattern, giving the watch an individuality that standard finishes cannot achieve. Paired with the warm tone of Everose gold, the overall effect is rich, textured, and visually complex without relying on bright colors or high contrast.

Technical Overview

• Reference: 228235-0045
• Case diameter: 40mm
• Dial: Eisenkiesel stone with natural patterning
• Case material: Everose gold-style finish
• Crystal: sapphire with Cyclops lens
• Bracelet: President, semi-circular three-piece links
• Movement: 3235-type automatic caliber
• Power reserve: 72 hours

The 228235 shares the same 40mm case architecture as other modern Day-Date references, but the Eisenkiesel dial is reserved for select Everose models, reinforcing the connection between natural stone tones and rose gold.

Inside the Movement

The 3235-type caliber provides a 72-hour power reserve and instantaneous day-date change at midnight. Operating at 28,800 vibrations per hour, it delivers a smooth seconds hand sweep. Like other Day-Date 40 models such as the 228206 and 228238, the 228235-0045 differs primarily in dial material and external execution rather than internal mechanics. For comparison with more uniform finishes, see the 128238 chocolate dial, which uses a consistent tone instead of natural variation. The broader Day-Date range includes multiple dial types, but stone dials remain among the most distinctive.

What Sets It Apart

Eisenkiesel dials introduce a level of organic variation that changes the character of each individual watch. The mix of deep red, brown, and subtle metallic flecks shifts under different lighting conditions, creating a layered appearance that evolves throughout the day. Unlike sunray or lacquer dials, the texture here is inherent to the material itself rather than applied. The Everose case enhances these tones, producing a cohesive and warm overall look. This replica Day-Date 228235-0045 stands apart from more conventional references by combining natural stone, unique patterning, and classic Day-Date architecture into a single, highly distinctive configuration.
