Product detailed description
ZF Factory’s Masterful Recreation — IWC Big Pilot IW501004
ZF Factory pays tribute to the iconic Big Pilot series by IWC with its meticulous reproduction of the IW501004. Fusing the bold spirit of aviation with refined mechanical aesthetics, this timepiece delivers a powerful presence and exceptional timekeeping performance.
【Movement Configuration】
•Powered by a custom-built Cal.52110 integrated movement, precisely replicating the original’s structure.
•Smooth automatic winding, stable balance wheel performance, and high timekeeping accuracy.
•Functions: Hours, minutes, seconds, power reserve indicator, and date display at 6 o’clock.
【Dial Details】
•Color: Classic charcoal grey / coal black sunburst dial.
•Hour markers: Arabic numerals with railway-style minute track, coated with luminous paint.
•Hands: Oversized sword-shaped hands with luminous filling for excellent legibility.
•Power reserve indicator: Positioned at 3 o’clock, with a bold red and white scale.
•Date display: Located at 6 o’clock.
【Case Specifications】The case features high-precision sandblasting, producing a fine matte finish that enhances the tactile feel and visual depth of the metal. This treatment reduces reflections, emphasizing the tool-watch heritage and field-readiness of a true pilot’s instrument.
•Diameter: 46mm
•Thickness: Approximately 15mm
•Crown: Oversized onion-style screw-down crown for effortless operation and iconic pilot styling.
【Strap & Water Resistance】
•Strap: Black calf leather strap, soft and comfortable, paired with ZF’s custom IWC-style folding clasp.
•Water resistance: Tested to approximately 50 meters – suitable for everyday use.
【Why This Replica Stands Out】
•Authentic proportions: Case size, dial print, and overall layout meticulously mirror the original.
•Integrated movement: Not a modified 9015 — ZF’s custom 51111 movement offers genuine back-view aesthetics and functional fidelity.
•Exceptional finishing: Luminous hands, brushed dial texture, and power reserve display all finely detailed.
•Wrist presence: The 46mm case delivers commanding wrist appeal — a true statement piece for men.
