The Chronomaster Revival A3817 is undoubtedly a welcome addition to the collection for those who appreciate one of the rarer early steel El Primero references, faithfully reproduced with all the charm and performance of the original. Through the open display case back, one of the few differences between the original A3817 with a solid steel case back and the Revival model, one can admire the legendary El Primero high-frequency automatic chronograph calibre that has remained a staple among chronograph movements for over 50 years.Ĭompleting the retro look and feel of the Chronomaster Revival A3817, two strap options are proposed: the first is the steel “ladder” bracelet, a modern remake of the Gay Frères bracelets that became emblematic of the early El Primero watches and the other is a light brown calf leather strap that will develop a patina unique to each wearer. The seconds track is done in a pyramid pattern affectionately nicknamed the “shark tooth” scale, which enhances legibility with a distinctly retro touch. The outer tachymeter scale also serves as a pulsometer, an especially handy and precise function provided by the high-frequency 5Hz (36’000 VpH) escapement of the El Primero movement. Like its ancestor of 1971, the Chronomaster Revival A3817 features a white lacquered dial with chronograph counters done in the instantly recognizable tones of grey and blue, with the running seconds counter at 9 o’clock done with blue markers, indicated by the single blue hand on the dial. Zenith waited two years after the launch of the El Primero in 1969 before introducing the iconic tri-colour dial to its sportier tonneau case, albeit with a slightly different execution in both function and aesthetic when compared to the A386. The Chronomaster Revival A3817 is crafted in the same angled tonneau-shaped case with pump-style pushers as the original, using historical blueprints and reverse-engineering to preserve the original proportions and finishes. Given that only 1000 of the A3817 were ever produced, it remains one of the most distinguished, elusive and sought-after references among the early El Primero watches. It combined the sportier steel tonneau-shaped case of the earliest steel El Primero references with the striking tri-colour dial of the A386, resulting in a unique and appealing aesthetic that continues to resonate with vintage chronograph enthusiasts. Released in 1971, the A3817 was the exception to the rule. On one hand, there were sportier models in tonneau-shaped steel cases, such as the A384, and on the other, more classical round cases in steel or gold, most notably the A386. When the El Primero calibre made its groundbreaking debut in 1969, Zenith chose to house it in two broad but distinct watch categories.
