The Constant Force Tourbillon is a limited edition timepiece from Arnold & Son that truly pushes the high precision chronometry boundaries.
Unlike other models, this unique piece offers two symmetrical barrels that switch between one another for optimal power output. The patented mechanism that supplies constant force rotates once per minute in one second increments and provides 60-second tourbillon to help average out any gravitational errors.
Basically, this watch is unlike any other. Crafted to complete perfection, the Constant Force Tourbillon is available in a 46mm 18-carat red gold case that features anti-reflective sapphire crystal and a sapphire display back.
The price tag on this little piece of luxury? Just a cool $197,500.
