A GMT Dive Watch set for those who loves a classic GMT

Red-Black "Coke" GMT watch-building experience. Amazing for those who love Rolex GMT Master

If you notice he loves Rolex and Tudors with a two-color bezel insert (the ring outside the watch), this kit can't go wrong.

The "Coke" Red Black GMT is a classic GMT style that is very sought after. It ties in with our "Batman" Blue Black GMT in popularity but we believe the red-black is a safer option as a gift. 

This is a Seiko GMT movement watch with sapphire crystal, FKM rubber straps and even comes with a ceramic bezel (which all watch lovers love). The watch is likely the best GMT in its class and the pro-tool kit pair very nicely with such a premium-looking watch.

We have YouTubers placing this watch side-by-side with their Rolexes, as this is a beautiful, self-built GMT that doesn't even have a hint of "I'm trying to be Rolex" on the design, yet shares the same attractiveness as their GMT-Master. Moreover, this is a much better conversation starter :)

• We made the hardest step much easier!

  We know. Installing that second hand for the first time can seem a little daunting. That's why we spent a year to invent this second hand installation tool for everyone.
