Beautiful Finishing

The case is masterfully done. One of the best 36mm aftermarket dress watch case out there, in my opinion. A special thanks for the great customer service. I will buy again for sure! #MyFirstBuild

Fit and finish are great, better bracelet fitment

The case is great all around, good transitions in finishing, and the improvement on the lug holes for the fitted bracelet fixes the complaints I had with the V1.

My only issue is with the eta2824/sw200 movement adapter, I wish they would provide movement holder screws along with it to mount with your movement. When transferring the eta/sw over to the provided adapter, the screws that sandwich the movement to its original holder would not fit the adapter due to lack of **** head diameter clearance to the inner sidewall of the movement holder. This could be an issue for some without proper tools or confidence in altering parts.

Amazing quality

The brushing on this case is top notch, best aftermarket case I've ever bought. All parts from this build apart from the dial were from Lucius Atelier and I couldn't be happier with all of them.

Excellent Quality Case

I really like the quality on this case (brushing/polishing/shape).
Installing the chapter ring/movement was easy because I just had to put the chapter ring on top of the dial before placing the case on the movement.

J. (Milpitas, US)
Beautiful case, but with one caveat

The fit and finish is very good; I could nitpick a tiny bit about the finishing in places nobody would ever see, but the finishing is perfect where it counts.

However, I did run into an issue where the Lucius Ateiler SKX013 chapter ring (mirror polished finish) that I had ordered alongside this case would not fit. It was slightly too big to slot in. I measured the chapter ring, and my calipers produced the expected 28.5mm outer diameter figure, so I'm assuming the case was milled a little too tight on the tolerances here-- and I'm guessing by just

Probably the best non-Explorer style 36mm case (3.5/5)

I was very lucky to get one of the last GS36 V1 cases.

- Looks really nice, I especially like the sharp, angular edges on the lugs that I feel are missing from V2
- Relatively simple mod, mostly just plug-and-play

- Has the tightest screwdown crown I've ever had - any deviation from 'perfect' alignment of crown stem and case will result in the crown being nigh impossible to use with bare fingers - a tiny application of Silicon Grease (for gaskets) alleviated the issue, but crown is still extremely tight. Most aftermarket crowns have no such issue, I really hope V2 has addressed this issue.
- Did not come with springbars
- AR coating could've been better - it's still very reflective and I feel a simpler flat or inner-domed crystal may have alleviated the issue.

- Aesthetically I prefer this over the Explorer case and the GS36V2, because it offers something more 'unique'
- Design would be perfect with perhaps a better crown with more 'wiggle room' like most aftermarket crowns, and perhaps being 'taller' larger fingers could grip it.
