Condition Report Overall: Though passed over a decade since its manufacture, this premium timepiece exhibits minimal signs of wear and has been meticulously preserved. It remains in fantastic, collector-grade aesthetic and structural condition.

The black hard-coated titanium case sides and lugs show no prominent scuffs or dings, retaining original sharp architectural lines.

The sapphire crystal is immaculate and scratch-free, offering an invisible, reflection-free view of the face. Bracelet & Case Back: The original titanium bracelet holds its rich black coated finish beautifully, free of notable scratches or fading, and the three-fold push-button clasp operates tightly and securely. The screw-down case back shows only minor, negligible hairline handling marks, while the central ASTRON earth icon remains perfectly sharp and well-defined. Functions: The GPS satellite synchronization, solar charging, stopwatch functions (start/stop/reset), and the calendar quick-setting are currently running properly and tracking with flawless precision. 4.
