Introducing the King of the “Monsters,” the Seiko USA Exclusive Ref. SRPD29

Share this story:

The “Monster” is undoubtedly one of Seiko’s most polarizing divers. Some swear by it, and others think the watch is true to its nickname in the worst ways possible. I’m personally a fan, in that I think it’s ugly enough that it actually looks quite awesome.

The Monster’s been through a number of aesthetic and technical overhauls in the years since it first appeared, and some have been better than others. The current Monster, which most categorize as the third generation in the series, is arguably the best looking one (at least it is to me). Most notably, gone are the shark-tooth markers of the previous model, replaced here with bold, blocky ones that are a better fit to the overall design. 

For the summer, Seiko’s added another member to the Monster family, and this one is a Seiko USA exclusive — introducing the Seiko Prospex Ref. SRPD29. 

Seiko Prospex Ref. SRPD29 “Monster”

  • Case Material: Stainless steel (black ion-plated)
  • Dial: Black sunray
  • Dimensions: 42.4
  • Crystal: Hardlex
  • Water Resistance: 200m
  • Crown: Screw down
  • Movement: Seiko 4R36
  • Strap/bracelet: Steel bracelet (black ion-plated)
  • Price: $550
  • Expected Release: Available now


The semi-shrouded case measures 42.4mm across and features a black ion-plated finish that ups the aggressive factor on an already aggro design. The black sunray dial continues the monochromatic vibe, and the dial features large, LumiBrite-filled markers for that awesome nighttime glow Seiko divers are known for. The same goes for the hands, which are additionally brushed here for a little added texture and better visibility against the black dial. Finally, there’s a black plated bracelet.

For this edition, Seiko brought back the day complication to go with the date, and on top of the crystal you’ll find a long, rectangular magnifier that enlarges both day and date. Spec’d to 200 meters (660 feet), the SRPD29 is ISO rated. 

As far as the engines goes, Seiko’s equipped the watch with their cal. 4R36 automatic movement. It features 21,600 vibrations per hour, approximately 41 hours of power reserve, 24 jewels, and it hacks and hand winds. It’s a solid movement, but a tier below the 6R15 now common to the Prospex range, which explains the dip in the price here. 

Altogether, this is a cool drop from Seiko, a brand that knows its way around tough, tool divers. At $550, it’s also reasonably priced for the overall package, and I’m willing to bet this will be a popular one. I’m already seeing some people calling this one “Godzilla,” which I guess makes this one king of the “Monsters.”

The watch is available now and is exclusive to Seiko USA’s online store. Seiko USA
