機芯

機芯

持續的創新與完善是格羅斯曼傳統的組成部分。因此,年輕的格羅斯曼錶廠持續進行眾多自主開發。貝努動力儲存腕錶機芯採用貝努系列著名的經典100.2型導柱機芯,帶有2/3夾板、階梯式擺輪凸輪,以及格羅斯曼典型的微調螺絲。

它具有MORITZ GROSSMANN GLASHÜTTE I/SA品牌機芯的所有標誌性特徵與手工藝細節。此外,更增添了全新的格羅斯曼擺輪、經過進一步改進的格拉蘇蒂棘輪、按鈕式手動上鏈裝置,以及動力儲存顯示。

THE ESCAPEMENT

THE ESCAPEMENT

The newly developed, asymmetricarm escapement has a smaller lever swing angle and a longer fork, which streamlines unlocking and improves the impulse behaviour.

Moritz Grossmann was already aware of the unwanted sticking effect of lubricants and countered it by minimising the contact surface between the escape wheel and the pallets. He did this by using pointed-tooth escape wheels that were commonplace in England, but we achieve the effect with a club-tooth escapement and particularly slender pallets. This significantly reduces the difference between the two impulses. The galvanoplastic production of the escape wheel allows small steps of merely 0.03 mm depth at the bottom sides of the teeth, so the capillary effect retains the oil better.

THE INDEX ADJUSTER

THE INDEX ADJUSTER

The adjustment function allows the oscillator to be tweaked very conveniently without necessitating its removal. The micrometer screw is easily accessible when the caseback is removed.

The cantilevered balance cock features a rotatable stud holder that is normally secured with the clamping screw which is visible on top of the cock. Thus, the micrometer screw can be used to sensitively calibrate the pointer and to accurately adjust the watch. As soon as the clamping screw is loosened, the pointer and the stud holder can be jointly turned to allow the beat to be set with the precise Grossmann micrometer screw without affecting the rate.

THE WHEEL TRAIN

THE WHEEL TRAIN

In this movement as well, the mainspring barrel is suspended between bearings on both sides. With the screwed ratchet wheel, the hollow barrel core is integrated in the train bridge and can thus accommodate the upper jewel bearing of the mainspring barrel. Here, too, its chaton assures that the ratchet wheel is centred. The going train features a classic centre wheel and a seconds subdial at 6 o‘clock.

The train wheels are made of ARCAP, a copper-nickel-zinc alloy finished with polished chamfers and circular graining to assure long-lasting beauty and brilliance.

黃金套筒

黃金套筒

軸承寶石——白色藍寶石水晶——安裝於凸出的黃金套筒中。與所安裝的、分別由手工退火的鋼質螺絲一起,它們突顯於夾板表面上方。這一凸起式佈局以傳統格羅斯曼腕錶為藍本,由此可以拆卸並清潔單獨軸承寶石,而不會在組裝時對夾板造成傷害。

手工雕刻

手工雕刻

2/3夾板上的所有鐫刻,以及擒縱輪板和擺輪凸輪上的鐫刻都由手工完成。
