It's a beautiful watch with an interesting dial. Very happy to have it. The band width is 20mm. The gap between the lugs is 20mm. Not 22mm stated is some specs.

Stylish, Reliable, and Smooth-Winding SEIKO Timepiece
I recently purchased the SEIKO SRPH31 men’s watch and couldn’t be more satisfied. The striking blue dial, complemented by the stainless steel case and comfortable blue nylon strap, exudes both style and durability. One of my favorite features is the 4R36 Caliber movement, which allows for both automatic and manual winding—offering flexibility and convenience. The day/date display is a practical addition, keeping me organized daily. With its 100m water resistance, this watch is perfect for everyday wear and various activities. Overall, the SEIKO SRPH31 combines aesthetics, functionality, and reliability seamlessly.

Great Budget Automatic Entry Seiko Watch
Picked this up on sale this is my first Automatic Seiko. This watch really appealed to me due to the style of the dial which includes the hours as well as the seconds. Some people say that it runs large but the watch case size is about 42.5 mm when measured fits perfectly. The glowing watch hands and indices are useful at night ,however it requires natural sunlight to be charged. The back of the watch is stunning. I also especially like wristband that is nylon on one side and leather on the other. I agree with others that the photo's don't do it justice lighting is poor in the product photos. This watch usually retails for around 300$ you can pick it up on sale for like 200$. My only gripe is that setting the date can be tricky for first time Datejust watch owners sometimes the watch would go into Spanish for the day of the month when I had set it in English. It only took a few times though to fix it. It can take some time for the day to change too which is normal just for your information.

The description of the watch in the advertisement is WRONG
I'm returning this watch right now, and I only opened it 5 minutes ago. The watch is beautiful, don't get me wrong. The thing is, I just spent good money having this nice watch sent to me, believing it was a 22mm band as it says in the description on Amazon's Website. Its actually only a 20mm band, and lug width. False advertising!!!!

I am very happy with the purchase of this watch. It is my first automatic watch. The watch case is very impressive, made of brushed stainless steel, and its size is suitable for my 7.5-inch wrist. The dial colors are harmonious and give the impression that the watch is modern and elegant. As for the watch strap, it is crafted with high professionalism, blending high-quality navy blue nylon with a soft orange leather lining that is gentle on the skin. It is a bit stiff at first but softens with time. Its thickness is compatible with the watch case thickness, and I do not recommend using any other strap, though this is my personal opinion. Among the negative points are the small date and day window, and the luminescence does not last long. Also, every two or three days there is a one-minute delay, and it needs to be reset... But overall, it is a wonderful watch, and I love it. Band width is 20 mm not 22 mm as mentioned here

This watch looks very beautifully designed in person, the way the case shape, colours, and strap work together. A lot of online watch reviews miss the point. They say things like "doesn't have a sapphire crystal, therefore not worth $xxx", like they just tick off the various features the watch does or doesn't have, and then say whether they think it is worth what you paid for it. No review I saw gave this watch credit for how much the strap has been improved over the previous model (SNK807). The new strap is a beautiful deep blue colour, comfortable, with the smooth orange surface next to your skin, and of a satisfying thickness that complements the watch thickness perfectly. The drilled lugs put an end to the problem of "clicky pins", where the pin ends can tend to move around in their sockets making a clicking noise that I find annoying. Don't worry about the stiffness of the strap when you get the watch. Just bend it back and forth a lot to break it in, and it becomes very comfortable. To cut a long story short, you are paying for something beautifully and uniquely designed here. As a graphic designer myself, I know how hard it is to come up with a design that is sharp and contemporary and original. That's what you're paying for here, and it is well worth it.

After following the instructions in the manual on how to wind the watch, the watch will not work for more than 5 minutes. The crown was winding 20-40 times, then worn for the day and the time was miraculously stopped for the majority of the day. I have several other automatic brands and they all work, while this is the only one that can not hold time. Amazon's AZ guarantee is a joke, they protect faulty products and will do nothing to help a customer.

Tenía expectativas muy altas , y revisando e utilizando este reloj un par de dias se sobrepasaron, materiales de calidad, diseño de campo, casual y algo formal, me gusta el diseño de la carátula.
