The screw down case back has a nice etched logo of scuba diver diving through the ocean and all the pertinent information such as sapphire crystal and the water resistance.


As the name would apply, the Master Explorer 1000 is rated to 1000m water resistant. I myself am not a professional diver, but I would have no qualms about going swimming or getting this wet. The case is  very well constructed and just seems like it could withstand a lot of abuse.

The dial of the Deep Blue Master Explorer is what sets this watch apart from other divers on the market. Deep Blue refers to this as a cool grey dial, which pertains to the hue, but really I think the name was a perfect fit as this dial is just flat out COOL! The dial is enamel with a sunburst effect, and as Deep Blue calls it, a unique Burst dial. You can see the pattern that was done to the dial, making it very unique indeed.


In certain light the dial looks greyish/black, change the light angle and it looks a light grey with other times a brownish hue. To give a little bit of contrast, Deep Blue went with a yellow second hand which is subtle but just enough to give the dial some color pop.

The hands and applied markers are done in a stark white lume paint, with the markers outlined in chrome. As you can see the hour markers are raised, giving a nice 3D effect to the dial.  Personally, there is not one thing on the dial I do not like. It is unique, eye catching, and you will notice yourself checking out the dial and the way the colors seem to change. Then realize you forgot to check what time it was.

Above the dial you have a sapphire crystal with a very clear AR(anti-reflective) coating. This crystal is top quality. No glare at all when in the sunlight or taking photos. The flat crystal does raise above the bezel though. This is the one thing I wanted to point out, as it is a pet peeve of mine. Exposing the crystal that much above the bezel does make it possible for you to chip or scratch if hit the right way. When a crystal is flat, it should always be seamlessly inset below the bezel. I see no reason to have it stick out above the bezel.


The bracelet is a 24mm wide at the lugs and tapers to 22mm at the clasp. The clasp is your standard flip lock dive clasp with a diver’s extension. Unfortunately, they only have 2 micro adjustment holes. This is  something that always aggravates me, because it makes it hard to get a perfect fit. The bracelet end links are very solid and fit well up against the case. The links are solid and thick at 4mm.  This model does use friction pins to remove the links, though. Many Deep Blue models use screws to hold the bracelet together, but this being a sub $500 model, they went with friction pins. It is relatively easy to size though, and the pins did come out with ease.

I've been an avid watch lover since the age of 7. Watches are not only my hobby but a passion. My favorite style used to be dive watches, but field or non bezel watches have been growing on me. When I'm not reviewing watches I am either cooking or with family and friends.


  1. Blue Master Explorer seems to me an excellent watch with in $400 range of watches

  2. Great review. What’s the crystal diameter? Do you think I can pull it off with my 6.5″ wrists?
