Considered as Patek Philippe's most important watch of the 1990s, the reference 3970 is the heir to the 2499 and even before that to the famous and rare 1518. Watch produced in four precious metals: yellow gold, white gold, rose gold and platinum .<\/p>\n

The rarity of the reference 3971 is dictated by the sapphire crystal caseback which allows you to admire the majestic CH 27-70 caliber and by the extremely limited production, thus making the ref.3971 one of the most sought-after in the collecting world.<\/p>\n

The Silvery dial is very balanced, although a lot of information is displayed on it. The counter at 3 o\u2019clock combines the leap year indicator and the 30-minute chronograph counter. At \u201c9\u201d o\u2019clock is the subseconds and 24-hour (or day-night) display. The moon phase and date are visible in the counter at 6 o\u2019clock. Finally, the day of the week and the month are displayed in two windows at 12 o\u2019clock. The surface of the dial has been kept absolutely perfect and clean.<\/p>\n
