Considered one of the most collectible grand complications produced by the maison, this reference was introduced in 1996. Its design was directly descended from illustrious predecessors, including references 1518, 2499, and 3970, yet it was elevated with a split-seconds chronograph function. By merging the perpetual calendar mechanism and a rattrapante chronograph, a pioneering milestone in Patek Philippe\u2019s storied history was set.<\/p>\n<p>Measuring 36.7 mm in 18K yellow gold, the case was designed for a balanced presence on the wrist, neither oversized nor too discreet. The crown with an integrated split-seconds button was strategically placed between two pump-style pushers on the right side, providing effortless control over the chronograph\u2019s dual-hand feature. Through the sapphire display case back, the meticulously finished, in-house manual winding caliber could be admired.<\/p>\n<p>An opaline dial was fashioned with applied 18K yellow gold Arabic indices, while small gold dots were positioned at select hours for enhanced legibility. Gold feuille (leaf) hands were selected as a nod to earlier perpetual chronograph models, including references 1518 and 2499. Two apertures at 12 o\u2019clock were reserved for day and month displays, while a recessed sub-dial at 9 o\u2019clock was included for running seconds and a 24-hour indicator. On the opposite side, a 30-minute chronograph counter and leap-year indicator were arranged at 3 o\u2019clock. The lower sub-dial was assigned to a moon phase display and a date indication, completing the wealth of complications.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><b>Patek Philippe &#8211; Bio<\/b><\/p>\n<p>Patek Philippe &amp; Co. was founded in 1839, located in Geneva and the Vall\u00e9e de Joux.
