| Schwungmasse /Schwingmasse rotor / oscillating weight
Explanation:
Ernst, Dictionary of Industrial Technology, gives "rotor" or "oscillating weight" as a translation for Schwingmasse in watches. IMO. Schwingmasse and Schwungmasse are one and the same thing.

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the flywheel.

Uninterruptible power suppliesEdit
Flywheel power storage systems in production as of 2001 have storage capacities comparable to batteries and faster discharge rates. They are mainly used to provide load leveling for large battery systems, such as an uninterruptible power supply for data centers as they save a considerable amount of space compared to battery systems.[30]

Schwungradspeicherung ist eine Methode der mechanischen Energiespeicherung, bei der ein Schwungrad (in diesem Zusammenhang auch „Rotor“ genannt) auf eine hohe Drehzahlbeschleunigt und Energie als Rotationsenergiegespeichert wird. Die Energie wird zurückgewonnen, indem der Rotor induktiv an einen elektrischen Generator gekoppelt und dadurch abgebremst wird.
Benutzt werden sie meist zur Ausgleichung von Spitzenlasten, Glätten von Leistungsspitzen, Rekuperation bei Elektrofahrzeugen und auch als Anlage zur unterbrechungsfreien Stromversorgung in Krankenhäusern und Industrieanlagen.

Anm.: Schwungmasse ist die gesamte Trägheitsmasse eines rotierenden oder schwingenden Schwungrades, hier der Unruh (balance-wheel). Deshalb kann man beide Begriffe hier gleichsetzen.

20 hrs confidence: (oscillating or excentric) weight or balance (wheel)
Explanation:
In my 1st answer I referred to the physical and mechanical terminology. But horlogists have a different terminology. First a remark to the context "Der Sichtboden aus Saphirglas gibt den Blick auf das mit «Côtes de Genève» verzierte Uhrwerk frei und präsentiert zudem die Schwungmasse, die zum ersten Mal in der Geschichte des Hauses in tiefem Rot lackiert ist.". It is ambiguously acc. MHO. It may refer to the oscillating weight used to wind up the watch or to the balance (wheel).
See what an oscillating weight is:
An oscillating weight axel is the small pinion that supports the oscillating weight in an automatic watch. The weight rotates with the motion of your wrist and the axel supports the weight and is normally held in place with a jewel.

Oscillating weight for automatic watch
Abstract
Oscillating weight for automatic watch movement, having a massive peripheral ring in the shape of an arc of circle, a connecting element connecting the peripheral ring to the weight's pivoting center, wherein the connecting element is set with a plurality of stones.
https://patents.google.com/patent/US20120243387
A mechanical watch uses an oscillating weight to ensure its functionality. It is a component that rotates freely inside the watch which creates energy that is preserved by the spring barrel through kinetic energy (movements made by the watch-bearer). This enables the functioning of watch as long as it is being worn.

Oscillating weight (Rotor)
Masse oscillante ou rotor
In a self-winding movement, a heavy metal disc that turns freely in both directions to wind the mainspring.
https://www.hautehorlogerie.org/en/encyclopaedia/glossary-of...
Unter einer Automatikuhr (Automatic) wird eine mechanische Armbanduhr verstanden, bei der die Feder bei Armbewegungen des Trägers durch einen Rotor in kleinen Schritten selbständig aufgezogen wird. Frühe Modelle von Automatik-Armbanduhren waren teilweise mit einer Pendelschwungmasse (umgangssprachlich auch „Hammerautomatik“) anstatt eines Rotors ausgestattet.
Der Rotor, der zumeist kugelgelagert ist, bleibt bei Bewegungen des Uhrgehäuses aufgrund seiner Massenträgheit und der Schwerkraft im Raum stehen. Hierdurch wird ein Drehmoment auf den Aufziehmechanismus ausgeübt. Typischerweise wird die Feder bei beiden Drehrichtungen (bidirektional) aufgezogen. Liegt die Drehbewegung des Gehäuses in der Achse des Rotors, so beruht das Prinzip allein auf dem Trägheitsmoment des Rotors (im Foto in der oberen Hälfte zu sehen). Dies funktioniert also auch in der Schwerelosigkeit. Bei Drehbewegungen senkrecht zur Achse des Rotors kommt die Exzentrizität desselben zum Tragen: Der Rotor ist zumeist nur halbkreisförmig ausgebildet, daher fällt sein Schwerpunkt nicht mit seiner Achse zusammen.
https://de.wikipedia.org/wiki/Automatikuhr
An automatic or self-winding watch is a mechanical watch in which the mainspring is wound automatically as a result of the natural motion of the wearer to provide energy to run the watch, making manual winding unnecessary.
:
A self-winding watch movement has a mechanism which winds the mainspring using the natural motions of the wearer's body.[1] The watch contains an eccentric weight that turns on a pivot. The normal movements of the watch in the user's pocket or on the user's arm cause the rotor to pivot on its staff, which is attached to a ratcheted winding mechanism. The motion of the watch is thereby translated into circular motion of the weight which, through a series of reverser and reducing gears, eventually winds the mainspring.
https://en.wikipedia.org/wiki/Automatic_watch
and what a balance is:
Balance
Balancier
A circular, moving part which oscillates on its rotational axis. It is coupled to the balance-spring which gives it the to-and-fro motion through which it divides time into strictly equal parts. Each to-and-fro movement ("tick-tock") is called an oscillation, and each oscillation comprises two vibrations.
A circular mass (rim) held by spokes. Combined with the spiral it forms the regulating organ of the watch.
https://www.hautehorlogerie.org/en/encyclopaedia/glossary-of...
Jede mechanische Armbanduhr hat als Schwingkörper eine Unruh. Diese schwingt mit einer durch die Spiralfeder vorgegebenen Schlagzahl, bei klassischen Uhren 18.000 Amplituden pro Stunde (entspricht 2,5 Hz), bei modernen Uhren meist 21.600 (3 Hz) oder 28.800 (4 Hz) Halbschwingungen in der Stunde. Einige Schnellschwinger erreichen gar 36.000 Halbschwingungen in der Stunde (5 Hz), z. B. die Longines Ultra-Chron, die Gyromatic Chronometer HF von Girard-Perregaux und el Primero von Zenith.
https://de.wikipedia.org/wiki/Armbanduhr
A balance wheel, or balance, is the timekeeping device used in mechanical watches and some clocks, analogous to the pendulum in a pendulum clock. It is a weighted wheel that rotates back and forth, being returned toward its center position by a spiral torsion spring, the balance spring or hairspring. It is driven by the escapement, which transforms the rotating motion of the watch gear train into impulses delivered to the balance wheel. Each swing of the wheel (called a 'tick' or 'beat') allows the gear train to advance a set amount, moving the hands forward.
