## Description

Seiko SRPG21 Prospex Special Edition Automatic Diver Watch. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and winning design. Inspired by Seiko’s most iconic diving styles, this distinctive Special Edition features deep 3D-pressed design in a striking black dial for increased legibility underwater. For reliable timing in rough waters, the 23-jewel automatic movement beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 41 hours, and can be wound manually or automatically. Featuring a magnified date calendar and LumiBrite hands and markers, the dial is framed by a black ceramic uni-directional rotating elapsed timing bezel. In stainless steel, with secure screwdown crown and caseback, anti-reflective sapphire crystal and deep blue silicone strap, this high-intensity timepiece follows ISO standards for scuba diving. Water-resistant to 200 meters.

Review: King of $500 Divers (UPDATED) - I was looking at sub-$1000 divers for a couple of months. Ended up going down the Seiko rabbit-hole and discovered the King Samurai. The list of features at this price shocked me: Sapphire Crystal, Ceramic Bezel, Bright (if somewhat short-lasting) Lume, 200m, White Dial. Nothing in this price range (aside from Baltic) came close. Plus there's something cool about this chunky, old-school Seiko aesthetic. It's not trying to be a Rolex Sub or a Tudor or Omega. It's very workmanlike in its design -- ESPECIALLY if you pair it with a Crafter Blue dive strap. For an extra $65 or so you can take this good watch and make it look great. I've had this beast for less than a week and have already dinged it slightly -- however this is one of those watches that looks better with some character. I smiled when I saw the little dent. Added Bonus: my watch arrived with a "Made in Japan" dial and a perfectly aligned bezel. Three cons so far: 1. Seiko 4R movement runs around 10 seconds fast per day and only has around 40 hour reserve (at this price that's reasonable) 2. Screw down crown can be a bit gritty at times 3. Gripping the bezel isn't easy with the stock strap and very tough with the Crafter Blue upgrade. Overall I'm thrilled with this stylish yet blue-collar diving beast. Guess we were made for each other :) UPDATE: As much as I LOVED that Crafter Blue strap from an aesthetic perspective -- the rubber irritated my skin so much that I went back to the original Seiko strap. I'm so glad I did. The experience reminded me of just how comfortable these Seiko rubber dive straps are. No irritation whatsoever and the band expands nicely during times that my wrist swells. So yeah, this watch is even better value because you can't go wrong with the included strap.
Review: Seiko King Samurai - seriously one of the best! - One of the best Seiko watches for men’s! It’s a daily wear and should last! Different styles and different ways of admiring a face plate! It’s your choice! I am a watch enthusiast since I purchased my own watch at 15! 40 plus years later! I have many watches and they all have a story! Rolex is out of my budget but I can tell when I find one that is worth the price! This one is a keeper and lifted my spirit! Size is perfect! I added a bracelet from Long Island Watch.com. Pinping the watch!

This is a very quality watch. Feels solid and very comfortable on the wrist. The face is really intricate and aesthetically appealing. Size isn’t too big or overbearing, sits just right. So far the accuracy is great. I’m really happy with the purchase. The shipping was FAST!!
