Description
The Jacob & Co. Oil Pump “first copy” (high-end replica) attempts to mimic the extravagant 49.5mm or 43mm rose gold case and the complex, animated oil rig scene. Key features usually include two moving rose-gold plated derrick “horse-heads” on a honeycomb grid, often activated by a pusher, and simulated piping and oil barrels.
Key Features & Description;
- Animation: Features a “derrick automaton” that moves up and down, simulating oil extraction.
- Design: Replicates the industrial look with rose gold-plated, hand-finished components, including gold derricks, pipes, and a barrel on the dial.
- Dial Layout: Typically features a honeycomb grill base, a pressure gauge-shaped power reserve indicator, and a separate subdial for time.
- Movement: Unlike the authentic Caliber JCAM33/JCAM53, replicas use automated, lower-frequency, or quartz movements to mimic the “flying tourbillon” appearance.
- Case: Large-sized, 49.5mm or 44mm, in rose gold-plated stainless steel with sapphire crystal and an alligator-style strap.
- Pusher: A pusher, typically located at 2 o’clock, initiates the animation sequence.
