Richard Mille RM004 42mm Openwork Dial Watch Ref# — USD 335,000

Richard Mille RM004 Split-Seconds Chronograph The RM004 represents Richard Mille's split-seconds chronograph offering, distinguished by its manual-winding movement and skeletonized dial construction. Produced from 2003 to 2010, this reference demonstrates the brand's approach to high-complication timepieces within a compact case format. The 38mm titanium case houses the manual-winding RM004 caliber, providing a 55-hour power reserve. The skeletonized dial reveals the movement architecture beneath a sapphire crystal. Water resistance extends to 50 meters, and the watch is fitted with a rubber strap. The fixed bezel maintains the case's streamlined profile. This reference appeals to collectors seeking Richard Mille's take on the split-seconds complication in a relatively understated package. The titanium construction and skeletonized dial execution align with contemporary preferences for technical displays and lightweight materials. The seven-year production run establishes the RM004 as a core reference within the brand's chronograph offerings.
