Seiko 2nd Generation Orange Monster with new 24-Jewel Automatic Movement #SRP309K1

Seiko 2nd Generation Orange Monster with new 24-Jewel Automatic Movement #SRP309K1

The Seiko Superior SRP309 is the new, second generation Orange Monster dive watch.

It retains the essentials of the original such as the excellent bracelet, case and bezel, while changing the dial slightly and going with a new 24-jewel Seiko caliber 4R36 automatic (self-winding) movement. You will notice right away that the hour markers are shaped like shark teeth instead of the original mostly rectangular shapes. The inner sixty minute markings are no longer displayed making for a cleaner, less cluttered look.

The biggest change is on the inside. The watch is now powered by a new 24-jewel caliber 4R36 movement which now can be hacked and hand wound. Hacking is handy for synchronizing the watch with another timepiece. Just unscrew the crown. Pull it out to the 2nd position and the second hand will stop while you set the time. Hand winding lets you power up the watch manually after it has sat unworn for a few days. The movement is more accurate also compared to the caliber 7S26 used in the first Monster.

The powerful Seiko LumiBrite luminescent material is of course still used and it retains the same brilliant glowing properties that made the Orange Monster such a huge worldwide phenomenon with watch enthusiasts and scuba divers. It is a very slightly different shade of blue-green this time. Still an awesome sight in the dark after charging it with a bright light source. You will also notice a new nicely machined crown that is a bit easier to grip than the previous version.

Lug width is 20mm. Case size is 43mm. Slightly domed Hardlex mineral crystal. Concave dive bezel to help protect the crystal. Stainless steel bracelet with a dual push-button deployant clasp with safety latch. Solid screw-in case back. Water resistant to 200 meters. Day and date window. It's a fantastic bargain.

    Perfect Orange Monster

    Posted by Sal on Mar 15th 2016

    This was my first order from Island Watch. I emailed Marc questions about the Seiko SRP309 "Orange Monster" and he promptly responded. The watch arrived well-packaged and in perfect condition. It keeps the best time of any of my automatics running at +1.7 seconds per day (SPD) out of the box. Experimenting with positional variation at night, I can get the watch to run within .5 SPD - incredible! The watch looks amazing with its vivid orange, shark tooth indices, great lume, and fantastic bracelet. It must be seen in person to truly appreciate. 5 stars for the Seiko SRP309 and 5 stars for Island Watch.

    A rare case of love it or hate it

    Posted by Tomas Novotny on Aug 18th 2015

    I needed divers and my wish was for automatic ones. That narrowed down my options a bit. When I first saw Seiko New Monster watches I thought they were ugly as hell, but I remembered them for one reason or another and the design started to grow on me slowly. Eventually I decided to pick them up here on Islandwatch (the orange ones of course) and I have to say I still keep enjoying them and wear them all the time. Such a refreshing design!

    Gorgeous diver's watch

    Posted by Ken on May 28th 2015

    I am very happy with my Orange Monster. I was concerned about the weight of it on my wrist but I quickly got used to wearing it and have found it to be quite comfortable. The watch is also very accurate. I love the orange dial and find that it seems to almost glow in dimmer light (the dial not the luminous markers). The case and bezel of the watch are very nicely finished with a good balance between brushed and polished surfaces. The knurled crown looks great too. Overall I am very pleased with my Orange Monster and Island Watch. I would highly recommend Island Watch to anyone looking to buy a watch.

    Great pricing and service. This guy actually responds to email. Watches (2) arrived promptly. These orange monsters have to be the best watch value out there, what great heirlooms for my sons.
