When you look at the SNA411, you might be intimidated by its dial. There’s a multitude of rings around its display, each with its own functions. It looks hard to read but if you take a good look, they’re easy to workaround.
There are large, circular markings that replace numerals
. Around them is a ring with the markings for the minutes passed, allowing you to easily track time. The circles are large and full of LumiBrite
, so you’ll be able to tell the time in the dimmest environments.
In the 3 o’clock position, there is a calendar, which is useful. That being said, the calendar only comes with the day’s date. This isn’t too much of an issue as the vast majority of watches out there are like this.
You’ll see 3 sub-dials
. Two of them are for the watch’s chronograph
, and let you measure up to 60 minutes and 1/5th of a second.
The bezel has a slide rule which any pilot would find handy as it helps with calculations. If you’re not a pilot, the slide rule adds a cool design element to the watch.
The dial is completely black with the watch’s hands being off-white. There’s a pop of colour with the bright yellow of the second hand.
The SNA411 is a product from Seiko, which means it has a Hardlex crystal window. Hardlex is Seiko’s version of mineral glass and is arguably stronger. It’s engineered to be shatter-resistant
, so you’re in very good hands.
The case is made of quality stainless steel. This makes it extremely durable and keeps corrosion at bay. You’re bound to drop the watch a couple of times but thanks to the stainless steel, the case won’t get banged up.
The case isn’t too big or small. It measures 1.65 inches (42 mm) across which makes it perfect for regular sized wrists. The case isn’t too thick either. It’s the perfect width at 0.511 inches (13 mm) so you’ll be able to wear it without working your wrists out.
The case has a range of bezel indents which makes it robust. The fact that it has a crown and two other buttons on the side adds onto its design.
While on the topic of its crown, it’s fluted
so it has an extra grip.
In terms of its strap, we don’t have much to say. It’s made from stainless steel like the rest of the device, so the watch comes with a bracelet.
The bracelet has 4 links and a push to release button, so getting the watch off you isn’t a hassle. It doesn’t just have a push-to-release button, but it comes with a safety clasp
The bracelet has a 0.811 inches (20.6 mm) width which makes it just the right size.
As a pilot, you can always trust your handy SNA411. The watch is a Japanese Quartz. Quartz watches are the most accurate watch types out there.
It comes with the Quartz 7T62 mechanism which is chronograph oriented.
The 7T62 allows the centre chronograph to tick 5 times per second
which is something seen in Seiko’s more expensive chronograph watches.
At the 6 o’clock position you’ll see an alarm sub-dial. To be frank, the watch’s alarm isn’t the loudest, but it’ll wake you up.
The alarm also functions as a dial that can track the time in a separate time zone
. This is pretty handy, especially if you’re flying somewhere.
Quartz watches are known to be very accurate, as mentioned. The SNA411’s time may differ by one or two seconds every 2-3 months which is impressive
The fact that it’s a Japanese Quartz also helps with its accuracy as they’re known to be the most thoroughly built.
The majority of pilot watches on the market are water-resistant. This is especially the case with the SNA411. If your aircraft ever crashes into the sea, your watch would survive the ordeal as it can last up to 660 feet (200 m) underwater!Seiko advises you to not dive with it on
. According to them, it’s only fit for swimming and scuba diving.
The fact that its dial is full of large, circular markings that have luminous paint on them helps with underwater use as the watch will light up when swimming.
Of course, it comes with a rotating bezel. However, we’re not too sure about the number of clicks it has. If we had to, we’d speculate that it has around 120 clicks.
It’s waterproof as it has a screwed-down crown and tightly screwed case. The fact that it’s made from quality stainless steel helps as you’ll never have to worry about corrosion.
