The Audemars Piguet Calibre 4400, the New In-House, Integrated Chronograph

The Audemars Piguet Calibre 4400, the New In-House, Integrated Chronograph

Perfect Replica

The dispatch of the Code 11.59 collection is a urgent second for Audemars Piguet. There has been no item dispatch of this extent in the course of recent years for the brand. In this regard, the Code collection introduction was the ideal chance to introduce a since a long time ago foreseen advancement that was reported a couple of years prior: the Audemars Piguet Caliber 4400, an in-house, integrated chronograph development – in no way, shape or form a little accomplishment since chronographs are amazingly hard to develop.

Long anticipated, finally here!

Until now, Audemars Piguet has made a couple of very good quality chronographs in-house in the Le Locle APRP produce. Notwithstanding, the brand depended generally on rethought chronograph developments – either integrated with the Piguet-based FP1185, or particular with Dubois-Depraz modules on top of the in-house 3120 Caliber. Finally, the hotly anticipated Audemars Piguet in-house, integrated chronograph is currently here!

The Audemars Piguet Caliber 4400 chronograph is a very good quality, present day chronograph that has been five years in the making. Its development focusses on execution and proficiency, and it incorporates a few interesting specialized specificities. The advancement began only a couple a long time after the appointment of François-Henry Bennahmias as CEO of the brand. In 2013, Bennahmias gathered his item and creation groups, in a real sense locking them in a meeting room and stating, “nobody leaves the room until we have concurred on the key alternatives and established the framework for the improvement of a chronograph movement“.

Following this order, Audemars Piguet created not one but rather two developments, both 14”’ in distance across and part of the equivalent family:

  • The AP 4300, a programmed base type – utilized in its AP 4302 variation in the Code collection
  • The AP 4400, a programmed, integrated flyback chronograph – utilized in its AP 4401 variation in the Code collection

Naturally, the two developments share a great deal for all intents and purpose and offer a few components. They use a similar barrel, similar controller and common parts for the keyless works or wheel train. The look and feel know about that of the past Audemars Piguet developments, specifically with the plan of the bridges.

Chronometric accuracy was a critical factor in the improvement of these two types. For upgraded security, Audemars Piguet has decided on a cross-over equilibrium connect rather than an equilibrium cockerel. On each side, there is a screw to change the equilibrium end shake. The oscillator works at 28,800 vibrations each hour. The huge equilibrium wheel has an inertia of 12.5 mg/cmto give ideal soundness. It highlights 3 damages and 6 change loads. The enormous barrel guarantees a sound 70-hour power save. Winding is bi-directional gratitude to two reversers with metal rollers – a comparable framework was at that point utilized by Audemars Piguet for the AP4101 Calibre.

If the crown/stem activity is conventional (Position 1 for manual winding, P2 for snappy date setting set, P3 for time setting), the keyless works integrate a keen protected arrangement. An oscillating pinion drives the choice of the capacity. At the point when the crown is pulled, a wheel (that becomes inclined!) draws in with the date revision wheel or the time adjustment wheel. This design stays away from any kickback when pushing the crown back in.

The Caliber 4400

The Chronograph Caliber 4400 is a top of the line, present day development with an emphasis on execution and proficiency. This huge development (32mm) is an integrated development with a section haggle clutch.

Start-Stop-Reset – One of the primary things to get your attention on the Caliber 4400 are the three twin mallets and sledge springs. The sledges are liable for resetting the hands. At the point when the brakes are lifted, the sledges fall on heart-molded cams rotating these until the mallets come to lay on the two shoulders of the heart and immobilize it.

The three sledge springs are practically indistinguishable and situated one close to the other. Not exclusively is the capacity smooth and complete however it is truly cool to see these in activity one close to the other, which is eminently featured by the engineering of the movement.

Flyback chronograph – The AP 4400 is a flyback chronograph, which implies it very well may be gotten back to nothing and restarted instantly with a single press of the catch. This capacity permits fast retiming without the requirement for pressing pushers multiple times in progression to stop, reset and start the chronograph. However, this implies additional complexity as the reset should be worked without breaking any part, and the sledges then should be withdrawn to restart the chronograph.

Decoration – Finishings on the Caliber 4400 include straight and roundabout satin brushing, Geneva stripes and perlage – on the two sides of the scaffolds, even in the concealed territories. The scaffolds include enormous chamfers, consummately precious stone cleaned. Engravings are gold-conditioned. The 22K gold rotor is openworked with the AP logo, which offers a sublime perspective on the mechanism.

As with all Audemars Piguet watches, the watches furnished with the Caliber 4400 come with a 5-year guarantee. For more information, if it’s not too much trouble, visit www.audemarspiguet.com .
