A very interesting and rare piece that few know about. All Cyclos watches feature an hour hand that actually gets longer or shorter as the day progresses.
The new 24-hour dual-phase watch combines the advantages of a classical analogue display with a clear differentiation between a.m./p.m. or the day and night cycles. This is achieved by dividing the double meaning of the usual 12-hour scale into two loops. A radially adjustable hour hand follows this excentric curve and indicates thus all 24 hours clearly, although rotating with normal angular velocity.
The first production run watches have been delivered since summer 2003. The two collections available are based on two distinct design principles: the sporty "a.m./p.m." models in stainless steel cases or the elegant "day & night" models in gold cases, with dark or light dial each.
Exceptional is the elegant "Transparent Edition", which reveals the mechanical finesse of the unique dual-phase module by means of a partly transparent sapphire crystal dial.
Mechanical with automatic winding, ETA caliber 2892-A2, luxury finish (perlage, with blued screws), modified with the CYCLOS DualPhase module for controlling the length of the hour hand, certified COSC chronometer, CYCLOS logo engraved into the rotor (Geneva stripes)
Hours, by means of continual radial displacement of the hour hand on a dual-phase scale (Pascal’s spiral), minutes, center seconds hand, date at 6 o'clock
Either black or silvered finish in all versions, color differentiation of the dual-phase hours scale ("a.m./p.m." or "day & night"), with a raised outer ring for distinction of the minute and second graduations, Superluminova luminescent numerals and hands (except "Transparent Edition")
Diameter 39,0 mm, height 12,8 mm, stainless steel (sporty models), 750 (18K) yellow or red gold (elegant models), water resistant to 50m, sapphire crystal front and back
Calfskin black (sporty models), alligator-black or brown (elegant models)
