More about Zenith A386 Vintage El Primero Tri-Color RARE SS

This is a vintage c. 1969 stainless steel Zenith El Primero Chronograph A386. There is a solid screw-down case back and round chronograph pushbuttons. The 37mm diameter solid two-body case, hooded lugs, and flat bezel are polished. The original silver dial has applied steel faceted luminous baton indexes, skeletonized white baton hands with luminous inserts, and a red center chronograph hand with a rectangular luminous indicator around a minute/one-fifth second scale. A quick set date aperture window is 4 and 5 o'clock. There is a perimeter tachymeter to 500 UPH, and inside on a plain black reserve is a 1/10th second ring. It has distinctive tri-color subsidiary dials, including a running seconds indicator at 9 o'clock, a 12-hour chronograph register at 6 o'clock, and there is a 30-miute totalizer at the three o'clock position. It has a 50-hour power reserve at full wind, and the 12.8mm thick case, dial, and movement are all signed.

This Zenith El Primero A386 has a mechanical automatic self-winding high beat El Primero caliber 3019 PHC chronograph movement. It's rhodium plated, and it's constructed with 31 jewels, 135 components, an Incabloc anti-shock device, and a straight-line lever escapement. It includes a monometallic balance, a self-compensating flat balance spring, and an index regulator. It has a dry molybdenum-sulfide based lubrication system, and an embellished tungsten carbide weight segment. The mechanism oscillates at a frequency of 36,000 vph (5Hz).

The Zenith El Primero Chronograph A386 was introduced in January of 1969, and c. 2,500 examples were produced until 1971. Because it beats at a frequency of 36,000 times per hour – twice that of the standard 28,800 vph movements, the seconds hand seems to glide rather than tick.
