What affects value
Exact reference, case material, dial variant, size, movement generation, condition, service history, full set and whether components are original or service replacements.
Indicative European market ranges in EUR. Exact value depends on reference, configuration, condition, originality, service history, completeness and current demand. This is editorial guidance, not a purchase offer or investment advice.
Model story.
RM 055 uses a skeletonised movement and a strongly structural case to create visual depth without a chronograph. Its apparent simplicity places greater emphasis on bridges, case condition and the relationship between movement and shell.

Buyer guide.
Check the case for chips or impact marks, verify movement stability and winding feel, and compare the watch with reference-specific factory imagery.
TimeHunter Insight
RM 055 rewards buyers who prefer openworked architecture over complication count. The condition of the case is central because it frames the entire design.
