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.
