Making a gen style 16710 case out of a 16570 case and TW bezel assembly

[bklm1234 17]

There are sub, YM, and Exp2 reps in gen construction. There was never a GMT II 16710 in gen construction. Just when I planned to do a gen style GMT II 16710 using the noobfactory Exp2 case and wm9 bezel assembly, the noobfactory terminated production of both the GMT II and Exp2. Sneed12 had the same idea and did one with the noobfactory Exp2 I believe.

 

With the new SL'd 40mm Exp2, it's possible to make an awesome gen style GMT II 16710 case again. It's even easier than using the noobfactory Exp2.

 

Stick a utility razor blade between the Exp2 bezel and the case

Pound on the razor blade with a mallet to open a gap

The bezel comes off, usually together with the crystal and gasket. Use a crystal press to push the crystal down and off the bezel. Don't push the crystal off from below. That ruins the gasket and possibly break the little ridge on the underside of the crystal

Now you have the bare case

Notice gen style crystal has an interlocking ridge on the underside

Here's the part why this case is easier to make a gen style GMT II case than the noobfactory Exp2 case

You can just get a 2.35mm crystal gasket and install the crystal and retaining ring. The TW sub bezel assembly is perfect for this project. With a Clark bi-directional click spring, the bezel turns both directions like a GMT II bezel should

Snap on a JewelryOutlet990 pepsi insert. CGs was trimmed. Voila, a gen style, high quality GMT II 16710. Perfect fit, perfect crystal height. Very easy.

That's the new exp 16570 that's already carried by Josh, Andrew, Angus, etc.
