The heavy, lustrous metal lends an understated authority and significant heft to the wrist, balanced by the model&#8217;s compact, classical dimensions.<\/p>\n<p>The silvered dial demonstrates the balanced architecture that has come to define Patek Philippe\u2019s high complications. Bounded by an outer track graduated to 1\/5th of a second, the display features applied white gold faceted baton indexes and matching baton hands. Twin apertures beneath the 12 o&#8217;clock signature present the day and month, while three multi-functional subsidiary dials orchestrate the complex array of indications: running constant seconds share the 9 o&#8217;clock register with a 24-hour day\/night indicator, a 30-minute chronograph register integrates the four-year leap-year cycle at 3 o&#8217;clock, and a radial date track frames a poetic fan-form aperture for the moon phases at 6 o&#8217;clock.<\/p>\n<p>Beating within is the revered Calibre CH 27-70 Q, a 24-jewel, manual-winding column-wheel chronograph movement with an integrated perpetual calendar module, built upon the celebrated Lemania 2310 base. Finished to the rigorous standards of classical haute horlogerie, it features exquisite hand-beveled steel levers, circular C\u00f4tes de Gen\u00e8ve, and a free-sprung Gyromax balance wheel.<\/p>\n<p>The watch is fitted with a black leather strap secured by an original Patek Philippe platinum deployant clasp. Combining the prestige of a platinum case with the enduring sophistication of the reference 3970, this ref. 3970EP-021 remains a definitive collector&#8217;s centerpiece from the turn of the millennium.<\/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.
