What customers say about "Key Specs"

Seiko SRP775 Men's Silvertone Automatic Diver Watch

I have a few mechanical automatic watches so I am by no means easily impressed. This is a rock solid timepiece.
When it arrived, I wound the crown a few times, and haven't thought about it since. Wearing it keeps it running just fine.
This watch is keeping time very well, losing only a couple seconds a week. That's more than good enough for me.
Thankfully, while 45mm, it wears smaller for several reasons; the short lug length, the shape of the case, and the crown at the 4 o'clock position.
The 4r36 is a proven movement that keeps great time and will last many years to come before needing a service.

I was concerned about the size because the SKX fits me perfectly. It is perhaps ever-so-slightly larger but has more of a square feel than the SKX.
it still retains the overall look and feel of the original "turtle" shaped cushion case that gives this iconic watch it's nickname.
It's 200m water resistance rating means you can actually dive with it.
I was initially hesitant because this watch looks mighty large and the dimensions given are quite large. However, a lot of that is accounted for in the "cushion" case.
This is my first automatic. I have to say that this is a great watch. It is beautifully built and looks far better in person than in any on line photo.

What customers say about "Materials"

Seiko SRP775 Men's Silvertone Automatic Diver Watch

Not too big or too heavy the cushion case makes it just right. I am used to German automatics that are heavier even without a bracelet.
The outer ring also has a gold brilliance to it that is beautiful and easy to read.
The gilted hands and golden lettering on the dial and golden numerals on the bezel insert make this an instant classic.
It's an awesome watch that's built like a tank and yet comfortable to wear all day.
The finish and polish of the case is quite beautiful and the dial face reeks of quality.

Seiko SRP777 Automatic Diver Black Rubber Strap 45mm Watch

The SRP777 works great as a daily wear watch. It's as good looking on the rubber strap as it is on a Nato, leather or a stainless bracelet.
The case design is rugged, yet elegant. It has highly polished lower edges and inner lug area, as well a brushed upper deck running the length of the case from lug to lug.
The watch face itself is smaller than the metal cushion case that surrounds it.
The included rubber strap is soft and extremely comfortable against the skin.
It looks good on the stock band or on a leather strap or a bracelet.

What customers say about "Features"

Seiko SRP775 Men's Silvertone Automatic Diver Watch

The lumibright is wow super. In the end you are getting a lot for the money.
Love this watch but wish I had a slightly larger wrist. Alas! My wrist is only 6.25 inches, so I had to remove 5 links.
Still, I love the larger crown on this model, the gilt trim, the feel of the hand-winding mechanism, the fact that it hacks and the much heavier band.
It also glows very well in the dark, so I finally have a watch I can read in the dark.
It arrives with a band large enough for a giant, I guess to accommodate all sizes of wrists. I had to remove two links, and adjust the connection to the clasp by two holes, and it fits perfectly.

Where the SKX hour markers have a flat feel to them, the hour markers on the SRP have just enough dimension that it feels like a higher-end watch.
Seiko has added drilled lugs. This makes watch strap changes a breeze for those how like to mix it up with different straps.
The 4R36 is a hacking movement, meaning you can stop the watch on a given second by pulling out the screw-down crown.
It's also a hand wind movement which comes in handy if you need to restart it after it's been sitting for a bit.
The watch dial features Seiko's proven Lumibrite lume over the indices applied to a slightly greyed-black face which offers great legibility.
