With the 544 RS, we present a mechanical timepiece that brings function and form into a balanced relationship -- clearly designed, precisely manufactured and focused on the essentials. The red seconds hand coated with luminous paint for daylight visibility sets a deliberately placed accent, lending the watch its own distinct, striking yet understated identity.
The bead-blasted stainless-steel case, with a diameter of 38.5 mm, impresses with well-balanced proportions and a restrained, contemporary presence on the wrist. Sapphire crystal glass on both sides frames the case with clarity and precision, while at the same time revealing the finely crafted mechanics within.
As reliable protection against the ingress of dust and moisture, the crown is equipped with our D3-System. Clear legibility is ensured by manually applied hybrid-ceramic luminous elements. By integrating the luminous pigments directly into the ceramic component, an exceptionally high concentration of luminous material is achieved -- the prerequisite for intense luminosity and precise readability in the dark.
Conceived for confident wear in everyday life and beyond, this timepiece is water-resistant, resistant to low pressure and pressure-resistant up to 20 bar. The automatic movement, visible in all its refinement through the transparent case back, impresses with a power reserve of at least 60 hours.
In terms of design, the 544 RS follows the successful tradition of defining timepieces from our company. Its form draws on proven design elements from models such as the 144 and the 244, translating them into a deliberately reduced aesthetic. The result is a watch that combines clarity with technical objectivity and integrates harmoniously into the Collection.
