Dial and Hands
The dial is a captivating deep blue featuring a subtle vertical brushed texture that shifts beautifully under varying light conditions. It is adorned with applied, faceted silver-tone stick indices that provide excellent contrast and legibility against the dark background. The applied Rado anchor logo sits proudly beneath twelve o'clock, complemented by crisp white typography including the elegant script reading "Slimline Square" above six o'clock. The slender silver-tone stick hands remain bright and clean. On close examination, the dial retains very strong visual impact, with only mild age-related peripheral wear and a few trace dust particles at the outer edge that are typical for watches of this period. The central display remains vibrant and clear.
Case and Crystal
The stainless steel case is a masterclass in geometric design, featuring a distinct profile with pronounced, sharp facets. The watch retains strong original finishes, with defined linear brushing across the top and bottom lug hoods and crisp transitions to the polished, angular case sides. The Rado signed crown is present and well-preserved. The faceted crystal beautifully amplifies the case's unique geometry and plays with the light. The crystal displays only light surface marks and modest edge wear from age-appropriate handling, while the case back retains legible engravings and light to moderate handling marks.
Movement
Powering this distinctive timepiece is the Rado caliber 505 manual wind movement, featuring 17 jewels. The movement is cleanly presented with diagonal brushed finishing across the bridges, gold-filled engravings, and bright rubies. Timegrapher results reflect current performance at a deviation of -48 to -53 seconds per day, indicating the movement is running and operational, offering reliable vintage performance. The balance wheel, gearing, and escapement appear visually clean and well-preserved in the provided macro imagery.
Strap
The watch is paired with a period correct black leather strap featuring a crocodile grain pattern and tonal black stitching. The strap is supple and in lightly worn condition, secured by a traditional polished stainless steel pin buckle that complements the bright accents of the watch case.
Condition
This Rado Slimline Square presents as an attractive vintage example. The case retains its striking faceted architecture and a pleasing mix of brushed and polished surfaces, with only light and honest wear from age. The deep blue dial shows mild signs of age along the periphery with minor dust, but maintains a vibrant and engaging appearance overall. The movement is clean and functional, contributing to an appealing overall presentation.
Dimensions
The case measures 30 mm in width, excluding the crown. The distinct geometric shape and integrated lug design provide a wearing presence that commands attention while remaining elegantly proportioned for a sophisticated vintage dress watch.
Remarks
This timepiece represents a fantastic opportunity to acquire a uniquely designed manual-wind Rado. The combination of the deep blue textured dial, the faceted crystal, and the sharply angled case makes it a standout piece that perfectly encapsulates the daring design language of mid-century watchmaking. It is a highly wearable conversation piece.
History
Rado has long been celebrated for its innovative approach to watch design, famously introducing scratch-resistant materials and highly unusual case shapes throughout the twentieth century. While models like the Diastar often dominate the historical conversation, elegant architectural pieces like the Slimline Square highlight the brand's versatility and its commitment to creating visually arresting timepieces that push the boundaries of traditional round watch profiles.
