Notes:

EXD: Exchangeable X Design(It can fit different style straps)

Heavy Duty 316L Spring Bar Pins Won't Rust, Bend or Break

EXD 38mm V2

We’ve upgraded the bezel to 60 clicks. The rotation now has stronger resistance and a louder than V1, EXD 40mm will be better clicks.

For the lume, we’ve made a appearance improvement in 3D BGW9 markers.

This time, the lume blocks are directly molded with transparent resin, resulting in a more even and cleaner structure, with a crisp 3D profile.

On V1, we applied additional lume printing on top of the molded blocks, which added thickness but could slightly alter the shape.

So:

V1 lume brightness: slightly stronger due to extra layers

V2 lume aesthetics: noticeably more refined and smooth,Lume good too.

Both versions deliver excellent lume performance — V2 simply looks better crafted.
