Muehle-Glashuette Terranaut I Trail Automatic German watches

Muehle-Glashuette Terranaut I Trail Automatic

The new Muehle-Glashuette Terranaut I Trail (refs. M1-40-53-LB in stainless steel & M1-40-63-LB in black PVD steel) automatic wrist watch is one of several timekeepers that were fairly recently introduced into the German watchmaker’s product range. Presented in an oversized body and offering superb legibility thanks to its high-contrast color scheme, the device is a perfect choice for a person looking for a relatively inexpensive pilot’s watch.




Like the last year’s Muehle Glashuette Terranaut III Trail Automatic model, the new version of the military-styled timekeeper sports a highly legible layout that seems to be at least partly inspired by styling of Bell & Ross pilot’s watches. With a very dark blue dial and its hands and hour markers painted with beige (MG calls it ‘sandy’) luminous substance, the timekeeper is predictably easy to read even though it demands some getting used to the way the beige-colored elements of the dial fight for your attention.

As you can see on the photos, the hour and minute hands of the watch sport that famous “diamond” shape that we usually see on old-school analogue instruments gauges of historic military planes.

Designed to be easily read in any lighting conditions and even in the most stressful situations, the hands also do a very good job on this particular model.

However, this new timekeeper is presented in a more prominent stainless steel case.

Available both in pure satin-finished steel, as well as in stealthier black PVD-treated steel, the body of the piece is whole 44 millimeters in diameter and is 13.50 millimeters thick, which brings a certain presence, but also makes the watch look really huge on a normal wrist.

Well, for a military watch, which is supposed to be worn with a bomber jacket, the size is not a problem at all.

As many other chronographs that were presented by Muehle-Glashuette during the recent years, this watch is, too, powered by their Caliber MU 9408 self-winding movement.

Although based on the wide-spread ETA Valjoux 7750 chronograph ebauche, this movement is heavily modified in-house with their patented woodpecker neck regulator, as well as with the signature Glashuette three-quarter plate. Of course, the caliber also features their trademark decoration pattern.

The watch is available now at a pretty much reasonable price. The model in steel costs just €2350 and the version with black PVD coating is only €100 more expensive bearing the €2450 price tag. Highly recommended.
