## 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: Worth the price. - 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!!

### ⭐⭐⭐⭐⭐ The perfect 200m Diver
*by L***1 on August 10, 2022*

Having followed a couple of 'influencers' on You Tube, I ordered this watch knowing that Seiko's QA has slipped over the past few years. Would I receive one with the dreaded misaligned bezel? A grey market? A knockoff instead of the real thing, especially at 25% off the list price? All I can say is this: If it's a knockoff, it sure has me fooled. Both the case back and the dial indicate the watch is made in Japan and the bezel aligns perfectly with the markers on the dial. It is a gorgeous, perfectly proportioned watch, and pictures do not do the work-of-art dial justice. Crown is large, easy to grip, and makes winding (when necessary -- this is an automatic) and adjusting the date and time a breeze. Lume is outstanding, definitely the winner of the 'lume wars' in my modest collection. I'm finicky and usually do not prefer date complications on a watch and typically do not like a cyclops on my crystal, but they are executed with aplomb on this Seiko and give it a Rolex-esque vibe while maintaining the classic Seiko style. The high-quality silicone strap is soft and supple and is thankfully not a 'lint grabber' like some silicone straps. 120-click bezel feels oil dampened and is second only to my much more expensive Oak and Oscar in quality and feel. Finally, losing less than a second per day, this Seiko is my most accurate mechanical. To sum up, I like this Seiko Prospex so much that (1) I bought an identical one for my nephew as a graduation gift, and (2) it's all but cured my watch jones (for now). If you're on the fence, have no fear. It's the real deal and it's a real winner. Definitely best-in-class at this price.
