    DESCRIPTION: The revised Seiko SRP309 "Orange Monster" with the new 24 jewel 4R36 mechanical automatic movement replaces the legendary SKX781 "Orange Monster" with the venerable 21 jewel 7S26 movement. Externally, the two watches are very similar, with the most notable changes being removal of minutes/seconds numbers from the watch face and use of a knurled rather than ridged stem on the new version. Internally, the changes are much more dramatic. The new 4R36 movement adds the ability to stop or "hack" the watch at any seconds position, allowing precise time setting, and it also adds the ability to hand wind the watch, both of which were missing in the 7S26 movement. Just as important, the 4R36 movement appears to have much better accuracy (ability to keep good time) and isochronism (changes in timekeeping due to state of wind and watch position), right out of the box. For those not familiar with this iconic and inexpensive timepiece, the Orange Monster is an armored stainless steel dive watch advertised as waterproof to 200 meters (658 feet). It is both rugged and reliable, but was not particularly accurate - until now. Its markers and hands rest under a domed mineral crystal on an orange watch face and are coated with a generous amount of LumiBrite, allowing them to glow perceptibly for hours after exposure to light. Hours, minutes, seconds, day and date are indicated - day and date through a window in the watch face at the 3 o'clock position. The crystal is further shielded by a sloped and very rugged unidirectional, stainless-steel timing ring whose inner ridge is lower than the outer ridge - the exact opposite of most dive watches - to protect the crystal. The timing ring moves only counter-clockwise, 120 clicks per revolution, and is very smooth and well damped in operation.Read more ›

    Bought this watch 2 months ago for a trip to Hawaii from Amazon reseller E Watch Stock, and now I can give it a proper review. To start, the new 4R36 movement can now be wound. The hacking feature allows you to stop the second hand and set it to an atomic clock if you would like. However, my copy gains about 7 seconds per day, so what's the point. What I do enjoy about the watch is the beautiful orange dial and the stainless bracelet. The watch feels as solid as a Navy destroyer. Here is my durability test: I wore it into the salty Pacific Ocean for 7 days strait, sprayed it with sticky sunscreen, and then dug moats around sandcastles in silty fine volcanic sand. Then into a chlorine pool every evening, and afterwards into a soapy hot shower. I would then take it off, rinse it and dry it with a hotel towel, and it always looked like new. The bezel still rotates with no indication that it was ever near a beach. I didn't get a single scratch on the crystal although I was banging around a concrete pool, this due to the sunken design of the glass. Now that I'm back from vacation, I actually wear this to the office, where it gets heavily complimented from co-workers wearing the standard Rolex and Breitling watches (which I also appreciate). My mother-in-law complimented the watch, so guess what... my father-in-law now wants one, but black, not orange. What else is there to say? Just get the watch, it's one of the best deals out there for a solid automatic watch that truly has some style, and allows you to go to Hawaii with the spare change. Cheers.

    I've had this watch about 24 hours now, so these are initial feelings.
    My other watch is an Omega Seamaster that is about 10 years old, it has needed to much attention recently so I have looking for a good watch to allow the Omega to enter retirement.

    The packaging was nice, appropriate for the price point. More than a plastic container to put on a shelf, less than the grand leather case of the Omega.

    Picking up the watch the first time, decent weight and size. Manly without being too much. The orange face is certainly not your dad's Rolex but if you are going far enough with this watch to read reviews you kind of like it. I kind of like it as well. The watch hands diameter are smaller for a face this size in my opinion. Real easy to read in day light or night (wow the watch glows in the dark!). Real solid and well built case. A real nice step up from the cheap watch options out there.

    It was easy to set the time, day and date once I found the right movement and language in the instruction booklet. Sizing the band might be best done by a jeweler unless you have a tool to remove the pins. (the little sleeves are super tiny, smaller than a grain of rice). I like the adjustability of being able to do more than add/remove links to seize the band.

    EDIT: I've now had the watch about a week. Lots of comments around about how bad the watch keeps time. I feel it keeps great time. Using my cell phone for the "official" time, the Orange Monster is less than 30 seconds fast in that week. I'l totally take that, my Omega was off 5 minutes I swear just screwing in the crown! Have gotten lots of comments about how great the watch looks.

    I'm loving my Orange Monster. Hope you love yours as much!
