Patek Philippe 5975 (Pre-owned - Good) — USD 68,290 on eBay

The Patek Philippe reference 5975, a limited edition chronograph, was introduced to commemorate the brand's 175th anniversary. This model is notable for its unique dial configuration, which foregoes traditional sub-dials in favor of three distinct scales: a telemeter, a pulsometer graduated to 15 pulsations, and a tachymeter. This design choice emphasizes the pure functionality of the chronograph measurements directly on the main dial. This particular version, the 5975G-001, features an 18k white gold case measuring 37 mm in diameter. It houses the manual-wind caliber CH 27-525 PS, a movement known for its column-wheel chronograph mechanism. The watch is fitted with a sapphire crystal and offers a power reserve of 55 hours, with water resistance rated to 30 meters. The reference 5975 appeals to collectors interested in Patek Philippe's commemorative editions and those who appreciate chronographs with unconventional dial layouts. Its limited production run and specific design elements distinguish it within the broader Patek Philippe chronograph lineage, offering a specialized instrument for timing various events.
