Mühle Terranaut I Trail Review

Mühle Terranaut I Trail Review

Mühle Glashütte is no more unusual to making intense and extraordinary jump watches, as we found in our audit of the S.A.R. Salvage Timer . Their inclinations, nonetheless, go past the profundities of the ocean and into land and air as well. While pilot watches are an extremely common thing (shockingly common when you consider the number of individuals are really pilots…), watches that are intended for land sports, by which I mean trekking, climbing, etc… are strangely more uncommon. With their Terranaut Trail line, Mühle has embarked to make looks for this very purpose.

With plans enlivened by pilot’s watches, the Terranaut’s have a controlled and appealing look with an accentuation on intelligibility. Huge hands and markers, all in khaki, are the mark of the line adding a heartiness to the range that addresses their motivation. Inside, the watches all element Mühle standard over the top development adjustment, making these a lovely extraordinary contribution. Of the three watches as of now accessible, the Terranaut I Trail stands apart a piece, as it has an especially fascinating dial and highlights Mühle’s MU 9408 chronograph development (which has a Valjoux 7750 base). Coming in at $3,335.00, the Terranaut I Trail is a remarkable watch with a particular plan, however a substantial sticker price that mirrors the custom development within.

Case: PVD Steel Movement: MU 9408 Dial: Black Lume: Super LumiNova Lens: Sapphire Strap: Leather Water Res.: 50M Dimensions: 44 x 53mm Thickness: 14 mm Lug Width: 22 mm Crown: 7 x 5 mm Warranty: Yes Price: $3,335.00


The Terranaut I Trail’s case configuration has its foundations in pilot watches. It’s a basic, straightforward plan that get’s the task finished, yet at the same time has a trace of tastefulness. At 44 x 53 x 14mm the silk/brushed PVD case is enormous however doesn’t appear to be curiously large or messed up. As with pilot’s watches, the goals behind the plan are perceivability in a functioning climate, so the scale has purpose.

From over, the case has an exemplary shape with a round and hollow focus and long, thin hauls that clear in easily. From the side, the multipart development is more evident and several highlights that amount to a more wearable watch. Similarly as with most cases, the Terranaut is separated into a bezel, focal body and case back, however the extents of the three are somewhat unique in relation to standard. Generally the focal body overwhelms the profile, yet here the three are more equivalent, with a tall bezel that chamfers towards the sapphire precious stone, a flimsy body and a delicately domed case back. The domed case back and flimsy focal body make the watch wear more slender than 14mm would suggest.

On the correct side of the case are the two chrono-pushers just as a 7 x 5mm screw-down crown. The crown is pleasantly planned and proportioned, with an effectively graspable authored side and shaped windmill logo on its end. The chrono pushers have a handcuffed plan that causes them to seem like they are screw down, however they are definitely not. The sleeve, which has a comparative begat surface, adds power to them and conceivably some insurance against hits from the side. Stylishly, I think it works pleasantly as it adds some toughness to the design.

The delicately domed case back, which is additionally PVD, is held set up by 5 little screws. In the middle is a huge presentation window, flaunting the pleasantly embellished MU 9408 development that controls the watch. Normally, this is valued as Muhle blows away the standard with their treatment of developments practically and stylishly, which contributes to a great extent to the cost of the watch.


The dial of the Terranaut I Trail has a ton of character, blending neatness in with some remarkable style and a prominently striking seconds hand. On the matte dark face are a few files and sub dials, as this is a chronograph, introduced in one or the other khaki or dim. The essential hour list is non-mathematical, comprising of slender yet strong square shapes that don’t differ fit as a fiddle or size, save where they are hindered by a sub dial. On the peripheray of the dial, outside of great importance file, is a moment/second list in dull dim, which has numerals at additions of 5, and little hash checks in between.

As with most Valjoux 7750 based chronographs, there are three sub dials; a brief aggregator at 12, a 12 hour aggregator at 6 and the dynamic seconds at 9. The chronograph aggregators are huge relatively to the dial, yet function admirably with generally speaking plan. Both are illustrated in khaki with lists comprising of khaki markers, which associate with the framework too dull dark lines and numerals. To additionally recognize these zones from the dial around, the whole sub dial has been given a silk finish, which the two causes them to seem more obscure than the encompassing regions and mirror light in an alternate manner.

The dynamic seconds subdial at 9 is a lot more modest than the chronograph aggregators, yet in addition includes a khaki boundary. The second hand, which Muhle alludes to as the “constantly pivoting capacity display” is the most special visual component of the watch. Rather than your ordinary hand shapes, they went with a symmetrical triangle that coordinates the distance across of the sub dial, and pivots about its middle. One of the purposes of the triangle has been set apart with a line, to make some feeling of a hand, however the motivation behind the triangle is more to show that the watch is dynamic. Outwardly, it is very striking, giving the watch a great deal of personality.

Text on the dial is restricted to the brand logo over the day/date window at 3 and “made in germany” in fine print around 6. The day/date is introduced in white on dark, keeping it genuinely inconspicuous. Taking into account that Mühle reconstructs their developments reasonably widely, I was somewhat astounded to see that they didn’t go the additional mile and make the content khaki to coordinate the motif.

Other than the three-sided dynamic seconds, the hands on the Terranaut are really clear, with standard shapes. The principle hour and moment are long and generally flimsy Roman blades, talking a piece to the pilot watch connotations all through, with dark edges and khaki tone lume. The chronograph seconds is a flimsy khaki stick with a three-sided tip and the chrono hours and minutes are thick fence posts. Generally speaking, the hands coordinate with the style of the watch well, looking after readability, adding some energy and being great proportioned.

The dial highlights SuperLumiNova on the essential file just as the moment and hour hands. Tragically, that restricts the chronograph work a piece and I anticipated (nay, need) the dynamic seconds triangle to shine also. By and large, the lume is normal, yet not extraordinary, similar to it was in the SAR. The blend of lumed khaki and non-lumed likewise makes for some shading minor departure from the dial. The lumed regions are paler, with a trace of green while the non-lumed are a touch pink.

Overall, I think the dial is fruitful. It’s sufficiently adapted to be special and vital, yet not so absurd as to be novel. I love the utilization of khaki and dark rather than normal white or green. The watch is the “Terranaut Trail”, and the khaki has a naturalness to it that addresses the idea of the watch. It’s additionally somewhat subtler that white or green, yet has sufficient differentiation to truly fly off the dark. All things considered, the khaki or “old radium” lume brands use tends not to be very potent.


The MU 9408 development within the Terranaut I Trail is Mühle’s reconstructed Valjoux 7750 Top. Not at all like different brands that just maybe re-beautify or manage (not to corrupt those highlights) Mühle dismantles the entire thing, resurfaces it and adds a few in-house components, a treatment they do to the entirety of their watches to fluctuating degree. On account of the MU 9408, they added house made blued screws, a Glashütte ¾ plate with perlage, their licensed woodpecker neck guideline, the programmed connect and the rotor. These highlights have practical just as stylish advantages, for example, the screws which are more erosion safe and the ¾ plate which has a removable break wheel connect for simpler support of the development and the woodpecker guideline, which adds stun insurance. Ultimately, they control the development to 6 positions, ensuring accuracy.

The adornment of the MU 9408 is excellent. Chronographs are consistently ideal to take a gander at, however the additional perlage, whirled graining, blued screws and fascinating rotor improve it all the. One thing I was astonished by was that the Mühle rotor configuration is intended to have 5 little bolts, which weren’t present on the watch we got. Practically, the MU 9408 is equivalent to the 7750, with 25 gems, day/date, chronograph work, hacking seconds, hand winding, a 48hr force hold and a recurrence of 28,800 bph. It’s an incredible development made far and away superior, so you know it’s going to last. All things considered, we saw the chronograph seconds had an intermittent falter, however that is likely atypical.

Straps and Wearability

The Terranaut I trail comes mounted on a 22mm dark Russian calfskin lash with hefty white sewing and coordinating PVD clasp. It’s a pleasantly caused tie with a delicate flexible to get a handle on right of the container. The plan includes a liberal measure of cushioning by the hauls, which has a decent look and makes the lash more comfortable. The white sewing, however not awful looking, might have been even more a cream tone to draw out the khaki in the dial, yet by and large it works. Something interesting I saw was that the lash that “new car” smell when I initially removed it from the box…which I really truly preferred. Given the cost of the watch, I would have jumped at the chance to see a second lash alternative accessible, either a wristband or something with a greater amount of a functioning game material.

Naturally, the long drags and pilot hints make the Terranaut look incredible with NATO style ties. I tossed one of our Gold NYC NATO’s with PVD equipment on there and it looked extraordinary. The yellow/khaki tones got the khaki in the dial while likewise adding differentiation to the case, and the additional mass functions admirably with the huge case design.

The Terranaut wears well for a huge watch, however it is maybe too huge for my 7″ wrist. The 44mm distance across is tempered by PVD, making it read more modest, however the 53mm haul to carry ranges over my entire wrist. The 14mm stature is entirely average, which as I said before is caused to feel more slender through savvy case plan. The vibe of the watch is essentially incredible. It has a fascinating stylish that addresses military plans while having its own special presence. The longing to make a game watch proposed for the trail comes through in the readability and khaki on dark colorway. Despite the fact that the watch is accessible in PVD or impeccable, the dark case adds to the intentionality of the general plan, as it unmistakably reflects less light.

As far as a day by day watch goes, it unquestionably is sufficiently vigorous to be a “go to” watch, however the style may restrict its adaptability. In other words, not probably fitting for dressy events, yet appropriate for easygoing to formal occasions. PVD is essentially less traditionalist, yet I think with khaki jeans and dark shoes, this watch would glance fine in an office. Obviously, with dark pants and boots, this watch will take a gander at home too.


One last thing worth referencing is that the Terranaut I Trail comes in a wonderful wooden box. Made out of lacquered hardwood with a serious shine mahogany tone, this is the sort of box you’ll keep around. The outside is itemized with pleasant joinery and simply an undeniable degree of finish. The case opens by pressing on a metal catch situated on the lower half, which is a pleasant purpose of association. Inside you have your standard set up with an opening for the watch and a pocket for archives, all in a cream shaded felt. All things considered, only an incredible presentation.


Whether you mean on utilizing the Terranaut I Trail for trekking, climbing, other game exercises or similarly as watch with chronograph work, it will surely be capable. The plan is fascinating and fun, with a tasteful that albeit natural is sufficiently novel to not feel subordinate. The turning triangle at 9 adds a great deal of character to the generally harsh plan, and is the sort of detail that can truly sell the watch. The MU 9408/Valjoux 7750 inside adds a component of fine mechanics that raises the general watch much more. It’s very uncommon to discover a chronograph at this value that has any in-house components, so that positively is an extraordinary feature.

With that said, at about $3,335.00, the Terranaut I Trail is very costly and has intense competition. The development changes go far, yet whether you wish to pay more for them is up to you. Plainly this isn’t a watch one purchases spontaneously, so the plan truly needs to prevail upon you. For me by and by, however I love the looks, yet the exorbitant cost is restricting. All things considered, the Terranaut arrangement incorporates some significantly less costly 3-hand watches, to be specific the 40mm Terranaut III, which at beginning cost of about $1,400 are considerably more enticing. Despite the fact that the three-sided seconds hand is remarkable to the chronograph, the three hands models address the land sport idea and have an overall quite clean plan as well.
