„Thus, we mortals are immortal in the lasting works we create together.“
– Albert Einstein
As one of the most important scientists of modern times, Albert Einstein’s research changed the previously accepted Newtonian view of the world. He became world famous for his theory of relativity, and his explanation of the photoelectric effect laid what is arguably the most important foundation for quantum physics.
The course of the sun in 24 hours

The mechanical and visual highlight is the 24-hour disc, which visualizes the course of the sun on a 360° scale. The disc is embedded in a multi-layered dial and features recessed symbols for the sun and moon. The color of the sun changes throughout the day from full red (noon) to deep blue (midnight). It is particularly useful for distinguishing between day and night when setting the time, and also for selecting the correct date change point at midnight.

E=mc² – The complication of the power reserve
The automatic watch has a power reserve indicator at the top of the dial, which shows the percentage of energy remaining (Einstein’s formula E=mc²) in the mainspring of the movement. The time during which the watch runs from full winding to complete relaxation of the mainspring without any further energy supply is also referred to as the power reserve or autonomy. In the “Relativity,” this is over 40 hours.
Thanks to the smooth-running rotor, the men’s watch winds itself automatically during everyday use. Alternatively, it can be wound manually using the crown.




The men’s watch is visually striking with a diameter of 43 mm and a thickness of 12 mm, a brushed body and a polished bezel. The 316L stainless steel cases are water-resistant to 5 ATM and, depending on the model, are silver-plated or double-plated in yellow or rose gold (IPG + real gold). The large glass back is screwed on and allows a view of the mechanical movement.

The dial and hands feature a clear, technical design and are protected by scratch-resistant sapphire crystal. Slim baton hands in a contrasting color ensure excellent readability, which is enhanced by thin Superluminova tips and luminous dots. The second hand is designed in a weaker contrast to the dial in order to achieve a clear, uncluttered hand display despite the complexity of the watch.
Features and scope of delivery:
The soft suede leather strap in black, brown, or anthracite is thickly padded, finely grained, and features a KRONSEGLER crest button and a safety folding clasp. The men’s watch is delivered in a KRONSEGLER watch box with a certificate magnetic strip card, a comprehensive 24-page booklet, and a polishing cloth.
