GEERVO 41mm Mechanical Hand Wind

I like:

Movement is of the pocket watch! ST3621

Dial looks amazing.

The overall look of the watch is very easy on the eyes, very nice.

It is a strap monster, a lot of fun on many different straps!

Blue antireflective coating on the sapphire looks nice.

This watch feels a lot smaller on the wrist then it is. Very stable.

Winding up this movement is a pleasant experience. 

I don't like:

Engravings on the movement.

Black paint on the movement.

Durability of the movement problems.

Also. Thanks Mister Hello for his insightful comment under my review video of this watch. I think it is worth posting it here as well:

"Lovely piece. A few thoughts, in reply to your questions in the video! I'm a history & industrial design buff in general and watches are an extension of those two interests.

The style of numerals are called Breguet numerals. Despite the name 'Breguet' (because he introduced them), they were and are found on many other brands. They were very common throughout the late 19th and early 20th centuries on pocket watches. With wristwatches, they were fairly common until the 50s when it started appearing 'old hat', and watch companies went towards including more metal on the dial (i.e. metal indices).

If you had a pocket watch in the 19th century and it didn't have Roman numerals, then it probably had Breguet-style Arabic numerals. The only real exception are railroad chronometers, which had a simpler style of numerals that you might associate with Western movies. That's because they're American in origin. But yeah, most pocket watches had Roman numerals and if they didn't, they would have Breguet numerals. They look best printed, so they didn't survive the transition to applied indices.

As you've said, wristwatches existed but only really started being worn with the First World War. These were often converted pocket watches which were more plentiful and easier to mass-produce. So these would be quite big! Military use began in the German Imperial Navy in the 1880s, where officers were issued watches in case they weren't near the marine chronometer. Context: a marine chronometer was basically a ship clock. It was very important because the time was the only reliable way to measure longitude at sea until the invention of radar.

Pocket watches remained popular over the 20s and 30s because wristwatches were very expensive, but pocket watches rapidly fell in price. So the pocket watch was the working man's timekeeping instrument for a longtime. The small pocket on your jeans (usually on the right) is for holding a pocket watch, and jeans were workingwear when men's clothing was more specific (blue collar meant blue collar, etc).

As you might imagine, pocket watch movements don't have amazing shock resistance since they were shielded (in your pocket) and mostly stayed in the same position (upright). As for this movement, I have no doubt it's a pocket watch movement since it's so big. Compare with an ETA 2892 for example, made specifically for wristwatches, and it's self-evident. It is only recently that wristwatches started matching the size of pocket watches again.

On the movement decoration I have mixed feelings as well. The jagged lines were very common in pocket watches, especially outside of Europe. The star in the centre also recalls some pocket watches, for example from Waltham which was by no means a high end brand. You got amazing value for money back then. Look up photos of Waltham pocket watch movements - I can see several similar examples on the first page. High end Swiss watchmakers like Patek went for striping, which was much harder to execute. British watchmakers preferred sand-blasting as a rule (and generally tended to come from a clockmaking background).

The other feature of note are the Breguet hands. Again, Mr Breguet introduced these in the early 19th century but they have been used by many brands since. At the time (early 19th century), there were few styles of hands because they were frankly hard to make. Remember that everything was handmade and we didn't even have steam power or electricity. Stamping a hole in the middle led to a more interesting design, and also slim hands in general. So he created a new production process (reversing the process of cutting hands) among the many inventions credited to him. Watch hands were very thick up to that point, nothing like what we know today. Most watch hands from before Breguet's time were engraved sheets of metal, and those had a different look. Compare a 1700s pocket watch (not many have survived of course) to an 1800s for reference.

As for your watch hands being blue: yours are chemically dyed blue, but high end watchmaking ships with 'blued hands'. It turns out that if you heat steel inside an oxidising solution, it turns a rich blue colour. It's quite difficult for watch hands since they're easy to melt and hard to keep looking consistent. So it's a marker of craftsmanship if you have 'the real deal' (luxury watchmakers like Grand Seiko, Breguet use them; the most accessible I'm aware of are from Pierre Paulin on Ali, and Stowa in Germany). All this to say that blue is the correct look for what the design is aiming at.

I hope those were interesting. As for what design is it, I think you're correct. I did an image search for 'Breguet numerals pocket watch'. The first result, a Longines pocket watch, is almost exactly like this, down to the railroad track. There are a lot more though from many defunct companies. I don't know how consciously the movement was designed, but it is reminiscent of American pocket watch movements of the late 19th and early 20th centuries. I agree it's a homage to pocket watches at large. Like you, I wouldn't call it a 'brand' homage because really it's about a period before the modern notion of brands, when many watchmakers didn't bother to sign the dial, and 'marketing activity' didn't exist. In that, it is reminiscent of a period and quite faithfully at that."
