200 Meters (660 Feet). Suitable for recreational diving, swimming, and snorkeling. Due to the age of the watch, water resistance cannot be guaranteed without a fresh pressure test and gasket inspection.

Age Estimate
Circa 2000-2005. The typography and '450' series numbering were most prominent during this period.
Cultural Significance
Represents the transition of the Italian watch market into professional-spec sports watches. During the 1990s and early 2000s, Sector was a major competitor to brands like TAG Heuer in the European market.
Condition Notes
Fair to Good. Visible surface scratches on the bezel and bracelet. Some scuffing on the high-polish areas. Dial and crystal appear clear, but lume may have faded. Bracelet shows signs of moderate wear and 'desk diving' marks.
Value Estimate
$100 - $250 USD depending on kit (box/papers). Value is primarily sentimental or functional; Sector watches from this era are considered reliable 'affordable vintage' rather than high-end investment pieces.
Care & Maintenance
Battery replacement every 2-3 years. If used for swimming, the gaskets should be pressure tested annually. Clean the bracelet with a soft brush and soapy water to prevent grit buildup in the links.
