El Primero Automatic A386



Iconeek is proud to extremely proud to introduce here what we call in the collectible watch market, a graal watch !, the original and highly sought after Zenith A386 El Primero, from 1970

The reference A386 is synonymous with the launch of the groundbreaking El Primero chronograph caliber in 1969.

Introduced at the Basel fair in 1969, the Ref. A386 was one of the first self-winding chronographs. The other two were of course the Caliber 11, and the Seiko 6139. Anyway, it was definitively the first automatic chronograph with high frequency, 36’000 alt/hour. In the Zenith collection, it was furthermore the only model available in stainless steel with a round case. Furthermore, the model was the only one fitted with much sought after intercrossing and multi-colored registers. The model was also the only one to feature a 1/10th second  division to highlight the fact that the movement was accurate enough, with its high frequency 5Hz,  to measure the 1/10th second. The El Primero Ref. A386 has become  extremely hard to find and is without any doubts the first choice for whose collect Zenith’s watches or High frequency 1970s vintage chronograph. According to the book Zenith, by Joël Duval the model, ref. A386, was produced between 1969 and 1972, a total production of 4500 examples in stainless steel. According to the book Zenith, by Manfred Rössler, Edition Damiani, only 2,500 examples of the A386 reference were produced between 1969 and 1971.

Rare, made in small quantities, well-powered with its column wheel high beat cal. 3019, the Zenith A386 has become an absolute classic. The kind of watch who immediately attracts the collector’s eyes.  The watch is a true classic, which is why Zenith reissued it several years back.

Versions of the A386 model:

The model can be split into three production runs:

– The Mark I, early production series, with case no. 538DXXX to 539DXXX, estimate range in the 200 to 400, with thin sub dials hands, plain (or smooth) case back, no groove on the lugs, slightly different design from the two other mark, dial with letter P (from CHRONOGRAPH) and letter C (from AUTOMATIC) perfectly superposed, winding crown set with  a four pointed star inside a circle inside case back engraved and centered, as follow, by order of appearance from top to bottom  « Zenith, Swiss Made, Acier Inoxydable » (no Spillman number)

– The Mark II,  such as the present watch, with case no. 706DXXX to 708DXXX, made between 1969 and 1970, with a bit larger sub dial hands, plain (or smooth)  case back, groove on the lugs, dial with letter P (from CHRONOGRAPH) and letter C (from AUTOMATIC) perfectly superposed, winding crown with four pointed star and a circle (on our model has a later crown), inside case back engraved and centered, as follow, by order of appearance from top to bottom  « Zenith, Swiss Made, Acier Inoxydable, SP 1205 » , such as the present watch.

Many dials on the A386s have been replaced, and service dials feature long tails on the end of the “O” in « El Primero ».


Why the model is actually so popular? because it was well-born. An incredible design combined with a multi-colored dial, rarely seen at the time, with the oversized intercrossing registers, and famous movement, the A386 is one of the most iconic wristwatches of the 20th century. Made in 1970, our model has a two-body construction,  a large 38 mm diameter stainless steel tonneau-shaped case with round chronograph pushers in the band, flat polished bezel, brushed pointed lugs,  a screwed case back, an hesalite crystal. Never subject to any polishing, the outer case back is clearly engraved with the serial number « 707D331 ». The inside case back is engraved «  SP1205 Zenith, Swiss Made, Acier Inoxydable » . « SP » stands for « Spillman ». Spillman is the case manufacturer for the A386 and other El Primeros. The size between the lugs is 19 mm. The case has only superficial scratches and has kept the original and unrestored profile of the faceted lugs that make it wear so nicely on the wrist.

Under the slightly domed plexi crystal, the dial is just stunning. A five-tone dial opalin silvered with black graduated ring, three guilloche subsidiary dials for the light grey constant second at 9, the grey 12-hour register at 6, blue 30-minute register at 3, luminous white hands with black tips, red central chronograph hands with luminous square tip, aperture for the date between 4 and 5, applied faceted rectangular steel indexes, with luminous coating, outer tachymeter scale. The indexes show a natural dark patina, consistent with age. Under the screwed case back, we find the famous caliber 3019PHC, automatic, certified chronometer, with high frequency and column wheel chronograph mechanism. The El Primero movement is to Watchmaking, what the Concorde was to Aviation, well in advance for his time and build to last. The movement remains today one of the most accurate chronograph, still in production, for its age.

With its big size, suitable for almost everybody, incredibly striking design, unmatched history, technical importance, great wearability,  the model has become legendary.  The tri-color dial, the early high-beat self-winding movement, the sharply angled case,  the great wearability of this watch all make it one to own, especially if you’re a vintage chronograph lover. The model has set the statement Zenith’s actual dna. Launched in 1969, the El Primero models continue to be one of the most popular Zenith watches still sold by the brand today. the El Primero movement is actually declined into 23 versions. The exact same model is illustrated in Zenith, by Joël Duval, édition Albin Michel, pages 318 & 319. The model is also illustrated in Zenith, by Manfred Rössler, Edition Damiani, page 249. Dial, case and movement are signed.
