Peace, mercy, and blessings of God be upon you, For sale: A very rare, fully Swiss, and classic Rado Diastar 0 watch. This specific version is historically documented and 100% accurate as the world's first scratch-resistant watch. The watch has been stored with extreme care and is in like-new condition (factory condition). The watch is very clean and like new, with the movement in excellent condition and operating with high accuracy. The watch's edition is Chronometer Certified, a rare version completely different from traditional ones, characterized by extreme precision in timekeeping. The watch case is made of highly durable, shiny, and scratch-resistant metal. The crystal is made of transparent, scratch-resistant sapphire glass, cut with unique angles and geometry that reflect light in a very charming and distinctive way, characteristic of this luxury category. The bracelet is original and very clean from the reputable Swiss company NSA. This company is a legend in the world of classic watch bracelet manufacturing. NSA used to make bracelets for the most luxurious major Swiss brands like Patek Philippe, Zenith, Heuer, and Rado. Their bracelets are known for exceptional flexibility and a very comfortable ergonomic design for the wrist, in addition to a flexible clasp that slightly extends for complete comfort with wrist movement. As this company ceased production decades ago, the presence of an original NSA bracelet in this clean condition significantly increases the historical and material value of the watch for collectors. Please note that the bracelet size is somewhat small, not long. Additionally, the watch is automatic and equipped with a date complication. Although it is rated as water-resistant, it is best not to expose it to water at all, as it is a vintage watch dating back to the 1960s. It is a collector's item, not for strenuous daily use. The watch comes with a Rado box as shown in the picture. The box is new and belongs to another Rado watch, provided as a replacement for the original box which deteriorated over time and years. The watch is considered a historical piece and a fully Swiss work of art sought after by collectors of watches and valuable items, especially in this clean condition with all original parts. Asking price (firm): 6,000 Saudi Riyals. Serious buyers are welcome. Please do not undervalue the item as it is rare. Location: Riyadh. Inspection and viewing are possible at any specialized and accredited watch shop to ensure the buyer's rights and verify the movement and bracelet.
