    The Seiko "Black Monster" is making watch history right in front of our eyes. Everyone interested in an automatc dive watch should look at this or its Orange, Blue or Yellow brothers as a "must have" watch. Every collector I know - no matter how expansive or selective - has a Monster in the watchbox.

    I am the owner of the Orange, Blue, Yellow, and Black Monster watches. The Blue is a "Limited Production" model - only so many made each year -- the Yellow Monster is already a legend -- only 300 made in it's Limited Edition and is no longer available through retail channels. Be prepared to bid at auction for this model.

    So - what makes the "Monsters" watches of legend...?

    The Black Monster's 42mm case is 316L stainless steel - featuring the Seiko made 7S26 21 jewel mechanical movement - not the best timekeeper in the world -- but accurate enough for most of us -- 15sec +/- daily. The movement is not able to "hack" and is not manually windable. Either you wear it every day or put it on a programmable watchwinder to avoid resetting the time/day/date. With screwdown crown at the 4 o'clock and screw-in back - the Black Monster easily is rated at 200M water resistance.

    The day/date is at the 3 o'clock and gives a good clear read - the watch face offering no magnification window. The change of day date can take up to 3 hours - not good for folks working the night shift. The plastic day/date wheels are of a self lubricating plastic and should give many years of trouble free performance.

    The stainless steel unidirectional scalloped bezel moves freely at 120 clicks to the minute. A perfect match to the sculptured case - the bezel also offers protection to the watch crystal.

    Originally written for the Orange Monster, this review holds equally true for the black version.

    From the moment you first hold this watch in your hand, you realize it is a quality timepiece. The first thing that strikes you is its large size and heavy feel, yet despite that, it feels comfortable on the wrist due to its fine balance.


    The bracelet end links (those that attach to the watch case) are solid rather than formed sheet metal like you will find on most other watches in this price range. The pins holding the bracelet to the watch are the sturdiest I have ever seen. Each of the bracelet's subsequent links is also made from a solid piece of steel, not folded sheet, each component being feather-edged to prevent it digging into the wrist. Its removable link pins are of an unusual machined pin and collar design which, though fiddly to remove and replace, nevertheless ensure that the pins remain under-flush and secure when correctly installed. The bracelet is perfectly flush on the side that contacts your wrist making it feel very smooth during wear.

    The clasp is very high quality, having both a fold over security buckle, which deploys with a satisfying click, and an Omega style double button catch. The security buckle closes onto a spring pin whose ends are spherical thus ensuring a tight fastening which should not wear with use. All in all these features add up to a watch that is very quiet on the wrist, the only faint sound coming from its automatic winding mechanism.

    Finally the bracelet incorporates a clever hidden diver's extension (to allow the watch to be worn over a wet suit).


    The watch case, back and bezel are made from stainless steel.

    I used to make fun of my friend who collects automatic watches. Then my wife got me a nice titanium automatic dive watch for Christmas a couple of years ago. It's as big as a clock and as heavy as a door knocker. Sound similar to anything we might be discussing here?

    The other day I dropped my beloved watch (made by an obscure German firm that specializes in "instrument watches"). Much to my horror, it fell off the nightstand and the hands froze. I figured I'd be without it for at least a month while the service center fixed it, so I took that as an opportunity to browse a few web sites to look for a temporary substitute. Wound up spotting this chunker.

    The Black Monster. Cool name, strong reviews, three year warranty, well known brand, unbelievable price, what's not to like? I considered its Orange Monster sibling momentarily, then decided to go with basic black.

    The Black Monster arrived today. Let me tell you, the pics on the site fail to do justice to this bad boy. It is one shiny big hunka steel, even more manly than the titanium timepiece my wife picked out. It took just a moment to set the date/time and adjust the stainless band. I put it on and really started to appreciate the heft of the thing and the huge glow-in-the-dark hands that contrast with the elegant black dial. (Must confess I have yet to try it with a dress shirt; might be a tight fit at the cuff.) I think I have a new favorite watch. Don't tell my wife.

    Epilogue: After I had placed the order for the Monster and it was too late to cancel it, I picked up my other watch--the titanium one--and much to my surprise and delight, it sprang to life! Of course, I couldn't bring myself to send the Monster back.
