More about F. P. Journe Octa Automatique Octa Automatique Reserve 18K Rose Gold

This is an 18K rose gold FP Journe Octa Automatique Reserve. It has a leather strap with a rose gold tang buckle, and a scratch resistant sapphire crystal. It has a screwed-down sapphire crystal display case back. The 40mm diameter solid two-body case, rounded bezel, and downturned lugs are polished. There is a silver dial with a Guilloche clous de Paris design in the center, painted blue Arabic numeral hour markers, blued steel Journe hands, and an outer minute track on a plain concentric reserve. It has a center hour and minutes, a small constant seconds sub dial between 4 and 5 o'clock, a large date aperture between 11 and 12 o'clock, and a power reserve indicator wedge at 9. Turning the crown in opposite directions at position 2 sets the date, and the time is set with the crown in position 3. It has a 120-hour/5-day power reserve at full wind, and it's water resistant to 30 meters/100feet. It includes a COSC certificate (Certified Official Swiss Chronometer), and the 10.6mm thick case, dial, and movement are all signed.

The automatic self-winding FP Journe caliber 1300.3 is 18K rose gold with fausses cotes embellishment. It's decorated with circular stripes on the bridges, a partly circular grained baseplate, gilt engravings, polished screw heads with chamfered slots, pegs with polish rounded ends, and the steelwork has polished chamfers and straight graining. It's constructed with 37 jewels, 293 components, and a shock absorber mechanism. It has uni-directional automatic winding, an in-line lever escapement with a 15-tooth wheel, a balance with 4 inertia weights adjusted to 5 positions, a flat Anachron microflamed spring, a mobile stud holder, a self-compensating free-sprung balance, a pinned GE stud, and a three-position crown slipping mainspring. There is an off-center bi-directional 22K gold guilloche rotor with a winding speed of 274 clockwise revolutions every 24 hours without mainspring slipping. The rotor oscillates with a frequency of 21,600 vph (3 Hz). The movement is engraved "Exclusive Power Reserve System" and "Precision Chronometer."

In 2001, FP Journe debuted the first automatic movement caliber from the Octa collection that guaranteed five days of precision timekeeping when unworn.
