The Rocail brand represents the height of early 20th century Swiss luxury and microengineering, renowned for finishing highly complex multicomplication movements primarily using foundational ebauches from speciality manufacturers like Le Phare. This magnificent grand complication piece unites astronomical, calendar, timing, and acoustical mechanisms inside a single pocket watch frame. It uses an advanced triple case layout where the solid gold outer lids conceal a specialized inner glass exhibition dust cover. This allows enthusiasts to safely observe the coordinated dance of the repeating hammers, calendar wheels, and chronograph switch levers in real time.
