An exceptionally clean example of the classic 40mm white dial Luminor Marina. This is an F-series production piece, dating its manufacture to 2003. It comes mounted on a vibrant, high-grade red alligator-grain leather strap equipped with an engineered stainless steel deployant clasp.

Condition: The polished stainless steel case and smooth bezel are in very good pre-owned condition, exhibiting normal, minor hairline marks and light surface swirls consistent with careful wear, but free of deep dings or egregious gouges. The sapphire crystal has two (pictured) very small scratches only seen at certain angles and lighting, and the internal date-magnifier (cyclops) provides crisp, clear legibility. The polished crown guard lever operates smoothly and locks tightly against the case.

Authenticity & Movement Health: Movement is the automatic Panerai Calibre OP III (built on the ultra-reliable Valjoux 7750-P1 base architecture). Verified for authenticity and performance: • Matching Serials: Fully intact and verified; caseback engravings (BB 107#### and edition run F0090/6500) align properly with correct factory production parameters. • Beat Rate: Timegrapher confirms a rock-solid beat rate of 28,800 VPH (4Hz), precisely correct for the OP III calibre. • Performance: Dialed into a highly stable -7 seconds per day with a strong amplitude of 260° and an absolute 0.0ms beat error. The trace line is exceptionally clean and flat, indicating healthy mechanical train performance. • Health: No signs of magnetism; amplitude and timekeeping remain steady and well within acceptable vintage/neo-vintage tolerances.
