|Zenith El Primero Stratos Flyback Watch Review|
Zenith finally gets more “toolish” in the El Primero line up, with the new Stratos Flyback Chronograph. Simply put, this watch is a knock out. Drawing much of the Stratos design details from Zenith’s historical “Rainbow” series and it is the closest version to date.
What is a Flyback? A flyback function is very cool if you have not had the opportunity to play with one. Unlike a conventional chronograph, the flyback function allows you to start with a single button push, then stop, reset, and start immediately with another single push. Conversely, with a standard chronograph you typically start with a button push, stop with a button push, reset with a button push, and finally start again with another single button push. With a flyback it is 2 button pushes vs 4 button pushes on a standard chronograph to start, stop, reset, and start again.
The El Primero Stratos has a black dial, with three black overlapping chronograph subdials. The date window is done in black font, with a white wheel, located at the 6 o’clock position. The white date wheel compliments the dial by blending nicely as a hour marker. Giving the Stratos it’s masculine appearance is the ceramic dive bezel. The bezel has a slight slope inward, drawing your eyes into the dial. Most bezels (unless internal) either slope outward towards the case or are flat. Though, this watch does have a dive bezel, the watch is still only water resistant to 100m. Remember, there are lots of other variables (example: impact) that factor into water resistance besides actual water depth.
The movement is the very well respected El Primero, specifically 405B. It beats at an impressive 36,000 beats per hour, with an estimated 50 hour power reserve. This automatic movement goes further using 31 jewels, decorated rotor done in a “Cotes de Geneve” pattern, and is enjoyed through the see through sapphire case back. The beefier size, movement, and the history combined, makes the Stratos a hard watch not to like.
Pros - El Primero 405 B, history, flyback chronograph, timeless
Consideration - Be cautious in water at only 100m WR, even though it has a dive bezel
