机芯

机芯

持续的创新与完善是格罗斯曼传统的组成部分。因此,年轻的格罗斯曼表厂持续进行众多自主开发。贝努动力储存腕表机芯采用贝努系列著名的经典100.2型导柱机芯,带有2/3夹板、阶梯式摆轮凸轮,以及格罗斯曼典型的微调螺丝。

它具有MORITZ GROSSMANN GLASHÜTTE I/SA品牌机芯的所有标志性特征与手工艺细节。此外,更增添了全新的格罗斯曼摆轮、经过进一步改进的格拉苏蒂棘轮、按钮式手动上链装置,以及动力储存显示。

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.

黄金套筒

黄金套筒

轴承宝石——白色蓝宝石水晶——安装于凸出的黄金套筒中。与所安装的、分别由手工退火的钢质螺丝一起,它们突显于夹板表面上方。这一凸起式布局以传统格罗斯曼腕表为蓝本,由此可以拆卸并清洁单独轴承宝石,而不会在组装时对夹板造成伤害。

手工雕刻

手工雕刻

2/3夹板上的所有镌刻,以及擒纵轮板和摆轮凸轮上的镌刻都由手工完成。
