For sale is an exceptional example of the Sector 255 Chronograph Alarm, a true gem from the 1990s, sourced from new old stock (NOS). The watch is in pristine condition, never worn, as confirmed by the close-up photos showing the protective film still on the case back and the complete absence of marks on the bracelet clasp. A piece that represents the golden age of Sector "No Limits," combining ruggedness and technical complications. • Condition: NOS (New Old Stock) - Never worn. • Movement: High-precision Swiss Quartz Movement. • Complications: Chronograph and Alarm/Alarm (a rare and useful feature). • Materials: Case and bracelet in sturdy steel, sapphire crystal. • Accessories: Includes its original vintage box (clean and well-preserved). Conditions of sale: The watch is pristine and unused; it has never been opened to avoid marking the caseback. It is sold with the original vintage battery still inside; therefore, its current functionality is not guaranteed, and it is sold for collection purposes or to be tested. Sold "as is" (inspected and approved) in the condition described above. The photos are an integral part of the description. As this is a private sale of a vintage "unused" item, returns are not accepted. A once-in-a-lifetime opportunity for collectors of vintage Sector watches to acquire a piece in factory-new condition as well as a true "time capsule."
