Water Resistance
200 Meters (660 ft); suitable for swimming, snorkeling, and recreational diving. The screw-down crown must be fully tightened to maintain this rating.
Origin & Provenance
Swiss Made (indicated by the movement and dial marking). Sector at this time utilized Swiss-based assembly and components to bolster its 'No Limits' professional image.
Age Estimate
Circa 2000–2005. The logo style and subdial layout are definitive of early 2000s Sector 450 production.
Cultural Significance
A staple of European sport-watch culture in the late 90s, the Sector 450 was part of the trend that popularized 'oversized' and ultra-masculine tool watches before the modern smartwatch takeover.
Condition Notes
Good overall condition. Visible light scratching ('desk diving' marks) on the bezel and bracelet. The bezel shows some wear on the high points of the embossed numbers. Dial and hands appear clean. Grade: Very Good.
Value Estimate
$150 – $250 USD depending on the market. These are considered nostalgic collectibles rather than high-investment pieces, but hold value well for their build quality.
Care & Maintenance
Requires a battery change every 2-3 years. To maintain the 200m water resistance, gaskets should be checked and pressure tested whenever the case is opened. Clean the bracelet with a soft brush and mild soap to prevent grit buildup in the links.
