Seiko is a watch company that originated in Tokyo, Japan. This Japanese product started in 1881. It became a corporation about a century ago in the year 1917. Seiko started as a watch and jewelry shop then they produced clocks and wristwatches in 1892.

The company’s name Seiko means “exquisite” or “success” in Japanese. In the year 1969, Seiko released the first quartz, the Astron, and it is the first one in the world. Today, the Japanese company Seiko is best known for their amazing and elegant wristwatches.

The Seiko SN411 is a wristwatch that measures up to 42mm and it’s actually smaller than what its specs would suggest on its details. The slide rule and the bezel use most of the visual space, so it leaves only around 32mm for the face of the watch. It is combined with the short lug with a distance of 44mm, the wristwatch is more like a 40mm watch than the advertised 42mm wristwatch.

The case design of this wristwatch is very basic, yet it is robust. It has a simple cylindrical barrel that is polished, and it has short legs that are straight, and it has a radially brushed and styled case-back encircle that has a black chronograph dial.

Around the right side of the case, you will see the chronograph pushers and the crown. It features a unique design that is screw-down, and it allows the buttons to be close together and locked in either a closed position or an open position.

The bezel of this wristwatch has a grippy type sawtooth edge and it has a smooth bi-directional motion or action, so it makes the adjustments and the calculations as easy as a snap.

The dial on this wristwatch is intense. The combination of reflective and raised surfaces, a moving cluster of the watch’s sub-dials and the slightly-domed crystal make the dial great and interesting to look at. The wristwatch is also shinier and more sparkly than its pictures would suggest, making it the best choice for formal and for business wear.

The yellow markings ties with the bright yellow chronograph of the watch, giving it a sporty yet elegant touch that supports its water resistance of about 200M. Its internal bezel is a bit sloped, so it enhances the overall readability and it lends a bit more interest in its vision.

This watch has a steel bracelet included which makes it lean towards the dressy and classy side of the overall spectrum. It has polished center links that match the case and it sets off some of the reflective elements on the dial.
