The Stuhrling Modulus 4064 is an exercise in controlled design and modern luxury. A brushed steel case and integrated bracelet form a continuous geometry that echoes architectural lines and urban precision. Its sunray dial — offered in deep blue, green, or black — captures light like a steel facade at sunset. Luminous hands and indices ensure clarity while the refined 10 mm profile slips easily beneath a cuff. Powered by a precision quartz movement and protected to 50 meters, the Modulus embodies the balance of art and engineering — a piece for the modern collector who values structure, clarity, and purpose.
