Earlier this year, Steinhart issued their new take on the concept of a “vintage-modern pilot”. Successfully blending vintage exterior with a classic caliber and modern CNC machinery, the 2018 Nav.B-Chrono 47 Baumuster B Grey Edition (ref. 106-0877) offers, perhaps, the best “value for money” ratio for those interested in buying a (relatively) affordable brand new “aviator”.
The Nav.B-Chrono 47 Baumuster: Overall Impression
No offense intended, but Steinhart enjoys a somewhat controversial reputation as a company that makes its living by selling “poor man’s Rolexes.”
Usually, they offer a combination of solidly built cases that house good Swiss Made movements, and exteriors that sometimes balance on the verge of intellectual property violation (their 2013 Ocean One Vintage is the first one that comes to mind.
However, the company is careful enough not to overstep the thin grey line.
Their timekeepers are especially popular among enthusiasts who always wanted that gorgeous Rolex with the colorful “Pepsi” bezel but never could afford one.
While the business model is frowned upon by die-hards and snobs, it has an advantage of sorts. When you spend a lifetime balancing on the shoulders of giants, you eventually acquire enough expertise to make products of your own (just ask Hyundai and Toyota.)
Their latest Baumuster B Grey is a great example of such an approach. The Germans took the classic B-Uhr, added a chronograph mechanism, and got a design that is both classic and original enough to blow (most) of competing micro-brands out of the water.
It’s A Cut-Throat Marker, Son
One of obvious competitor here is Laco: another niche brand of German origin. Their chronographs are smaller, but the brand offers lots of customization options.
While operating in the same ballpark in terms of price and exterior finish quality, it also has one advantage over Steinhart. It is one of the original watchmakers that supplied the German Luftwaffe with the original “Navigators” and “Observers.”
Steinhart, conversely, is just one of many makers of “homages.”
Some may even find the lack of “heritage” a serious drawback that undermines Steinhart’s “value proposition.”
Luckily for Steinhart, neither Laco, nor Stowa (another serious contender when it comes to affordable “pilots”) have chronographs in “Baumuster” design in their product ranges.
Also, the latest Steinharts use premium mechanisms from ETA (unlike Laco that installs Japanese calibers in their cheaper timepieces,) which is, too, a serious “plus” when it comes to value.
The 47mm Case Feels Too Big
Steinhart uses the same case design for all of their 47mm-sized cases. While looking great, they also have a design flaw that some may consider a deal-breaker.
Not Very Comfortable
The case is deliberately flat and this flatness exacerbates its overall thickness of 16 millimeters.
Another potential problem is the way the spring bars sit above the case’s “waistline.” At 150 grams, it’s not heavy on paper, but its top heavy and almost 5oz of ill-positioned weight may make the watch feel awkward on some wrists.
Together with the German brand’s official return policy (in three words, it’s difficult), buying one of these devices without trying first may become an adventure in itself.
The overall size of this thing, too, may give a rational person pause. For an overwhelming majority of customers, the Nav. B-Chrono 47 collection is just too big.
I, for example, have a 21cm (roughly 8 3/8 inches) wrist, which is just slightly above what is considered the average for men. Still, I find a watch that is larger than 45mm in diameter extremely uncomfortable, not only in terms of the “deadweight” but also in the way it constantly reminds me of its awkward presence.
So, again, if you have never experienced such a monstrosity on your wrist, think about a way of test-driving one before committing to this model.
After all, at more than $1k, the trinket is fairly expensive and, taking into account its potentially lower than normal resale value, you don’t want to lose a couple of hundred dollars trying to get rid of it.
Poor Water Restance at 50M
The gadget’s water resistance rating of just 50 meters (5ATM) doesn’t sound particularly reassuring for a sports activity watch. Steinhart explicitly states that it is “limited water-resistant, no swimming or shower.” However, I would be very careful even washing my hands while wearing this piece.
The Overall Ergonomics Is Good
If the size isn’t a problem, then congratulations are in order.
Both the “historic” oversized crown and the pair of push-pieces are also defiantly huge, which makes operating the watch a breeze. The knurled crown provides great grip even for persons with relatively thick fingers. The anodized orange “Start/Stop” buttons are wide enough for me to operate the chronograph without feeling any discomfort.
There’s nothing here really that I would want to change.
The Strap Looks Nice
Steinhart sells this timepiece on a black “vintage” leather strap.
I am not sure how long it will last, but it looks nice, especially with that cream stitching. The grey steel “butterfly” clasp makes putting the watch on easier than a simple tang buckle. Even you decided to upgrade it for something better, its standard 22mm width will make finding a replacement a lot easier compared to brands that offer their own proprietary designs.
The Mechanism: Caliber ETA Valjoux 7750
The movement here is the good old Caliber ETA Valjoux 7750 in its “Top” grade variety.
Still, even in this price range, the quality of timekeeping varies noticeably from one mechanism to another. Some lower-grade calibers may be better at keeping time than some higher-grade ones. There are, however, same major differences between the “Elabore” version (which is considered a base one for the cal. 7750 family) and the “Top” one.
First of all, the “Top” versions are adjusted in five positions (CH “dial up”, FH “dial down”, 6H “crown left”, 9H “crown down”, 3H “crown up”) whereas they only regulate the “Elabore” versions to the three most common positions when the watch is lying on its back and its sides.
The second is, of course, the finish. This one looks a lot nicer than most basic calibers sporting blued screw heads and Geneva stripes on bridges.
As with their other recent models, Steinhart tried to make the mechanism look even better by adding a gilded and sandblasted (and even partially skeletonized with the brand’s “crown” logo) oscillating weight to the whole assembly. Yet, I still think that the German watchmaker needs to invest more time and effort into designing something more appealing.
The personalized oscillating weight in its current form doesn’t add much to the gadget’s overall perceived value.
All in all, this is a great movement that, while not looking particularly stellar (and being rather noisy, but in a pleasant sort of way,) is usually good at keeping time -especially after a brief visit to a good service person- and is not very common when it comes to watches listed below €1000.
The Dial & Legibility
The main selling point of the Baumuster is the dial, which is good from any perspective.
While most chronographs are characterized by their dramatically lowered legibility compared to normal three-handers, this one does a good job at its primary function: telling time.
The sword-shaped hands are large enough to be easily read from any angle (the contrast color scheme and the sapphire crystal with anti-reflective coating help a lot,) and there is enough space on them for bucketloads of Superluminova that make the dial extremely legible even in twilight.
Some people may not like the way the Arabic numerals on the minute chapter are covered in lume in an alternating fashion, but that’s one of the key characteristics of the “historic” B-Uhrs, so there is no reason to complain here.
The orange elements on the other three hands (namely, the central chronograph seconds hand, the 30-minute totalizer at 12-o’clock and the small seconds sub-dial at 6 hours) are, regretfully, not luminous: it’s just orange paint, but the layout is still contrasting enough to be seen in normal lighting.
The only legibility issue here is the date window. Being as small as it is, it may be sometimes difficult to read. Also, given how broad the minute pointer is, it will be completely hidden from your eyes for at least four minutes every hour: something that I find a bit irritating.
Pricing & Availability
At the time of the original publishing of this review, the Steinhart Nav.B-Chrono 47 Baumuster B Grey Edition (ref. 106-0877) was available at Steinhart’s online store at a fairly affordable price of €990 (approximately $1150) with the sticker price including European VAT, but not including shipping and handling.
For those living outside the EU, the price is lower at some €832. From where I stand, this is one of the best choices for those not willing to pay five or six times more for a pilot’s watch issued by a premium brand.
