The Ernst Benz Chronolunar Automatic is almost comically large on a thin alligator strap but that does not stop it from being a real attention seeker. Ernst Benz specialized in these sorts of pieces and for them to make timepieces any smaller would be anathema to their designs. The watch was designed in Michigan by Leonid Khankin and assembled in Switzerland.

The Ernst Benz Chronolunar automatic movement

This watch uses the Valjoux 7751 movement found in any number of similarly-featured watches. This includes a number of Omegas, Zenos, Glycines, and most interestingly, custom watch projects. Think of the movement like an CPU and ETA and Valjoux as Intel and AMD. Many manufacturers use the same movement in multiple watches and the wild fluctuations in price from a thousand or so nearly $10 grand, are entirely based on case-type, finish, and of course sadly the marketing. In the world of high-end watches, think of Ernst Benz as a boutique manufacturer like Alienware or Falcon Northwest.

The size of Ernst Benz Chronolunar Automatic

What Ernst Benz does best is big watches. This watch is 47mm in diameter, and the watch is almost too big for any man’s wrist. Ernst Benz has fitted all of the complications, the features in with the face style quite nicely.

The dials, face, and features

The big Gothic hands are quite readable, the register hands the 24-hour dial is unlumed, which makes the watch fairly useless as a date calculator in the pitch dark, but that can be forgiven the complexity of the dial.

What does this big watch do actually? Well, the two pushers on the sides start and stop a chronograph with sweep second, 30 minute, and 12 hour counters. the thin hand with the red tip notes the day of the month while a small window at twelve o’clock notes the month and day of the week. The register at nine o’clock shows 24-hour time AM/PM, essentially, and a running seconds.

The durability of Ernst Benz Chronolunar Automatic

In terms of durability to worry about is scratching the stainless steel case. The rest of the watch is sufficiently protected and the case is water-resistant to 5 ATM or 50 meters. It is obviously more of a “dress watch”.

Overall Ernst Benz Chronolunar review

Here comes the bad news, expect this model watch to hit about $6500 in stores, which is not that much for this type of watch but is still far out of the range of most calm, rational people. However, if you are looking for an example of the Valjoux 7751 that looks great on the wrist, this one deserves a chance.

You can find similar timepieces online and on Amazon for a few thousand, as well, if you are looking for the style and feature but not the high price. Either way, it is a fascinating artifact of the mechanical age.

Ernst Benz ChronoLunar Review
The Ernst Benz Chronolunar model is essentially with a 7751 movement. It is a large watch at 47mm wide because Ernst Benz offers four dial styles, 2 Black and 2 White with either steel or gold trim. The steel case is polished all over and has a classic timeless feel to it.
