A classic explorer watch case that withstood the test of time. An excellent choice to finish a build.

This new version 2 explorer case comes complete with clear AR sapphire, sapphire caseback, screw down crown and solid brushed oyster bracelet. The bracelet clasp is also designed to have micro-adjustment without the need for removing or adding links. Additionally, explorer watch case has a water resistant of 200m.

Now in DLC BLACK EDITION!! Every visible exterior of the watch case when worn is coated with black DLC. Right down to the little screws on the bracelets and joints.

What is DLC?
Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. As the name suggests, diamond-like-carbon means that the layer is as scratch-resistant as diamonds. DLC coating has 5 times the hardness of a 316L stainless steel. With DLC being harder than steel, this means that a DLC coated watch will have a very high resistance to scratches that you will not have to worry about scratching your watch. This coating will not disappear if you accidentally do something that would otherwise leave a huge mark on some PVD-method coated watches. A feature that is highly coveted by many watch enthusiasts.

Designed to fit all of our dials (28.5mm) and original NH movements (grey dial holding spacer).

New Feature!
Ability to fit ETA2824/SW200/SW260 and ETA2893/SW330 movements. Special spacer and caseback provided.

Photos shown here are a prototype. There will be 2 significant changes to the final product:

  1. The bezel is brushed as shown in the photo here. However, the final product will have a polished bezel like the first version explorer case .
  2. The oyster bracelet endlinks will have a better 3D depth.
This is Pre-order. Please kindly place an order ONLY if you can afford to wait. Tentatively, we are only producing 100 pieces of each design.
