The Dark Water 300 was first conceptualized in a series of sketches in the early part of 2018. Our original designs had included a total of 9 different color combinations which we painstakingly narrowed down to 5. During our prototyping phase, we created physical copies of each of the 5 color options, but eventually decided that we would market a single black on black watch to be named the ‘Dark Water’. Over the course of the next few months, we began to showcase the first productions sample of the Dark Water 300. Our customers loved the design, but a strong contingent of fans began asking for a second blue color option. Due to the requests, we officially released the Dark Water 300 in August 2019, in both the original black on black, as well as the requested blue colorway.

These very limited model Dark Waters are almost identical to the official production models, however you will notice the following differences on the Prototype Edition dials:

- Thinner Hour and Minute Hands
- Japanese Luminova as opposed to Swiss SuperLuminova
- Different Date Window Design

Less than 5 units of each prototype color were ever assembled, making these watches extremely rare

*NOTE TO BUYERS: These are not reproductions, these are the actual original prototype watches that are now available for sale. There may be signs of wear such a small scratches on the case and or bezel. Please keep this in mind when making your purchase. All watches are in perfect working condition and come with a 1 year warranty.

To ensure both a luxurious and durable finish, the casing of the Dark Water 300 is cast from 316L stainless steel. The 43mm case has a brushed satin finish which compliments the more shiny areas of the watch handsomely. With a total height of 13mm, it feels and looks great on the wrist. The bezel of the Dark Water is anything but typical. The 12-sided, unidirectional bezel comes with a ceramic insert which provides incredible resistance against scratches and scuffs. The rim of the bezel has been finished with a high polish shine, which looks great against the brushed case.

Protecting the face of the watch, you'll find a thick piece of ultra scratch-resistant Sapphire glass. The crown, which has been signed with the Kingsbury 'K', screws down for ultimate protection against leaks. The combination of the sapphire glass, screw-down crown and stainless steel case lets the Dark Water 300 boast an impressive water resistance of 30ATM / 300M / 1000FT. 

The distinctive dial of the Dark Water 300 is what really sets it apart. The first thing you'll notice is the beautiful wave pattern that's been etched out in the center of dial. The hour markers, like on any good dive watch, are bold and sport luminous material that glows in low light conditions (when charged). The 12 o'clock position gets a double baton marking to help you easily identify the time, when working or playing in the dark. 

On the outer rim of the dial you'll find printed numerical markings that make reading the time even easier. For the minute and hour hands, we've chosen a set that are bold, thick and taper into a point, while the second hand resembles an archer's arrow. At the 3 o'clock position is a the calendar window, with a metallic border, that shows both the day as well as the date. With all the design features, you'll feel a strong sensation of quality and precision each time you look down to check the time. 

No dive style watch would be complete without some sort of luminous features and the Dark Water 300 is no exception. The Dark Water Prototype Editions used Japanese Luminova elements which appear white under normal and glows during low light conditions (when charged).

The striking luminescent hands make it easy to tell time even in the dark. To further aide in reading the time in the dark, we've added Japanese Luminova to the hour markings. This feature is not only functional, but gives the watch a unique glowing design.

Our rubber strap is custom designed for the Dark Water 300 and is made for both durability and comfort. It has been constructed from high quality silicone and features our 'Kingsbury' brand tattooed on the stainless steel buckle. The width of the strap is 22mm and tapers down to 20mm,  which adds a sleek look no matter what the environment. 

The caseback on the Dark Water is constructed from 316L stainless steel and has a screw-down design allowing for the tightest fit and best protection against water. Each caseback has been engraved with the make and model indicator of the timepiece. Featured prominently in the center of the caseback is the a sea creature's tentacle holding a trident, the mark of the Dark Water 300.

The NH36A is a Japanese movement manufactured by the famous watch maker Seiko. It’s a great movement that provide accuracy, dependability, and longevity that is used by several watch companies worldwide. This is a 3-hand automatic movement that has both a day and date indicator at the 3 o'clock position. 

The NH36A employs a winding rotor that winds the mainspring which stores energy and transfers it through a series of gears and springs, regulating the release of energy to power the watch. There is a built in hacking function that helps you set the time in the most accurate way possible. The movement runs at 21,600 BPH or 6 beats per second and has about 40 hour power reserve. In addition, it has 24 Jewels to help keep the movement running efficiently.
