Mechanical perfection is our definition of accuracy.

Through an ample, non-reflective sapphire-crystal display back, the calibre 100.1 movement reveals itself to aficionados of fine timekeeping instruments as a fusion of the arts. Subtly proportioned components in untreated German silver with different types of finissage constitute the individual levels. As was the case in Glashütte pocket chronometers, the movement consists of a main plate and a 2/3 plate precisely spaced apart with two posts and the barrel bridge. Raised gold chatons and pan-head chaton screws add three-dimensional accents. The brilliant glitter of hand-polished chamfers on going-train wheels and the edges of levers and springs resides in the depths of the movement as well.
Several innovations in the calibre 100.1 movement are noteworthy in the ways they further optimise the handling convenience and functional reliability. The newly designed Grossmann balance can now be crafted in-house in its entirety. A further modification of the Glashütte stopwork created space for the Grossmann winder with pusher.
格罗斯曼摆轮
The ATUM breathes at a calming traditional rate of 18,000 semi-oscillations per hour. The calibre 100.1 incorporates the newly designed Grossmann balance and demonstrates that rate accuracy is not achieved solely with a higher frequency. Optimised for artisanal manufacturing techniques, the design of the balance improves the adjustability of inertia and achieves high kinetic energy combined with minimised air resistance and the smallest possible mass. The number of screws in the balance-wheel rim was minimised as well. Mass screws with different head lengths are used to incrementally vary the moment of inertia. Additionally, the rim is provided with uniformly spaced bores that allow reductions in mass or contribute to the poising of the balance. The smooth cylindrical balance staff is integrated in the hub and can easily be replaced if necessary. The Grossmann balance interacts with a Nivarox balance spring which is overcoiled with a quarter arc on the inside and secured to the slotted roller with a brass pin.
格罗斯曼按钮式手动上链装置
一枚手动上链腕表平均每星期就应重新设置一次。格罗斯曼的制表师以更高的操控与功能可靠性应对这一挑战。只需轻轻拉出上链表冠，全新按钮式手动上链装置便会变为指针设定模式，并同时掣停机芯。上链表冠立刻回到初始位置，现在可以对指针进行精准设置。之后可以通过上链表冠下方的按钮重新启动机芯，无需再次拉动表冠。由此，此装置同时变回上链模式。借助这一完美的指针设定装置可以消除两种可能的故障源头：在设置流程中杂质侵入表壳，以及在推入上链表冠时误调指针。
三重阶梯式太阳纹饰
上链轮系在齿轮上带有抛光边缘倒角，由此赋予了零件最高亮度。棘轮作为轮系中最大的部件还装饰有传统的三重阶梯式太阳纹饰，与宽形条纹以及手工雕刻的整体外观和谐相融。
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
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。
